.NET Core is a new version of the .NET Framework, which is a free, open-source, general-purpose development platform maintained by Microsoft. It is a cross-platform framework that runs on Windows, macOS, and Linux operating systems.

.NET Core Framework can be used to build different types of applications such as mobile, desktop, web, cloud, IoT, machine learning, microservices, game, etc.

.NET Core is written from scratch to make it a modular, lightweight, fast, and cross-platform Framework. It includes the core features that are required to run a basic .NET Core app. Other features are provided as NuGet packages, which you can add to your application as needed. In this way, the .NET Core application speed up the performance, reduce the memory footprint, and becomes easy to maintain.

Key Terminologies in the Architecture of .NET Core

The key terminology in the architecture of .net core is as follows:

Let us see the key terminologies in the architecture of the .Net Core.

Core CLR: Core CLR is the Common Language Runtime optimized for multiplatform and cloud-based deployments. This, along with .Net Native Runtime, forms the foundation of all. Net-based platforms.

.Net Native Runtime: Also referred to as Managed Runtime, .Net Native Runtime contains the native windows based libraries. This also contains Ahead Of Time (AOT) compilation instead of the erstwhile Just In Time (JIT) compilation. This improves the performance of the applications. The .Net Native Runtime and the Core CLR are the layers that contain implementations of primitive types as well as generic collections in .Net. These layers hardly change and are constant throughout the various .Net stacks. The various .Net stack APIs, thus, share the same implementations.

Unified BCL: The Unified Base Class Library, also referred to as CoreFX, consists of the basic classed that form the core of the .Net Core platform.

App Models: On top of the BCL, sit the various App Models that developers leverage to develop platform-specific applications. Currently, .Net Core has the ASP .Net Model for web development and Windows Store Model for windows application development.

There are some limitations with the .NET Framework. For example, it only runs on the Windows platform. Also, you need to use different .NET APIs for different Windows devices such as Windows Desktop, Windows Store, Windows Phone, and Web applications. In addition to this, the .NET Framework is a machine-wide framework. Any changes made to it affect all applications taking a dependency on it. Learn more about the motivation behind .NET Core here.

Today, it's common to have an application that runs across devices; a backend on the web server, admin front-end on windows desktop, web, and mobile apps for consumers. So, there is a need for a single framework that works everywhere. So, considering this, Microsoft created .NET Core. The main objective of .NET Core is to make .NET Framework open-source, cross-platform compatible that can be used in a wide variety of verticals, from the data center to touch-based devices.

.Net Core is a platform on top of which there are frameworks such as ASP .Net Core and Universal Windows Platform that leverage and extend the features of .Net Core.

Let us look at the features of .Net Core that make life easy for developers.

Cross-Platform and Architecture: .Net Core follows the principle of build-once-run-anywhere. Thus, it is cross-platform. It supports Windows, macOS, and Linux platforms. You can build your application on any platform and run it on another. Also, an application built in .Net Core is consistent in its behavior across any architecture such as x64, x86, or ARM.

Command Line Tools: .Net Core comes with easy-to-use command-line tools for those who like to code black and white. These tools are handy for local development as well as for continuous integration of code in repositories.

Flexible CI/CD: .Net Core supports Continuous Integration and Continuous Deployment. Thus, you only need to worry about code logic. Rest is all handled by the .Net Core platform.

Languages and IDEs: .Net Core applications and libraries and can be coded in C#, F#, and Visual Basic. This is further supported by integration with your favorite IDEs such as Visual Studio, VS Code, Sublime, Vim, etc.

Compatibility and Support: Compatible with .Net Framework, .Net Standard, Mono APIs, and Xamarin. Being open-source, it has great support from the community as well as from Microsoft.

APIs: .Net Core exposes APIs for many general-purpose as well as high-performance scenarios. On one hand, there are APIs for primitive data types (bool, int, etc.) and Collections (Lists, Dictionaries, etc). On the other hand, there are APIs for high-performance types such as Vector and Pipelines.

.Net Core is truly cross-platform. This is Microsoft’s future platform for integrated development environments for the devices of the future. .Net Core focuses on Web, Windows Store, and touch-based devices.

.Net Core will greatly help you in making applications that cater to the future needs of devices and platforms. The design principles of .Net Core ensure that you follow the best practices of development. There is a rapidly growing need for a more robust and interactive application experience, be it web-based or mobile-based. This, in turn, drives the need for an improved, simpler, and developer-friendly platform. Gone are those days when an application developed in one platform would not work on another platform. Today demands to develop applications that are built once and run everywhere. .Net Core is built upon this ideology and learning it would help you create better applications for modern devices.

The .NET Core platform is not like its predecessor .Net Framework. It is a new .NET stack that is optimized for open-source development and agile delivery through NuGet. While the .NET Framework was designed to be cross-platform, it was largely a Windows-only platform. .NET Core is truly cross-platform. Microsoft is looking to be future-ready and .Net Core is a very fruitful step towards that. It is recommended for interested readers to deep dive more into .Net Core by reading Microsoft Developers blogs. For those who are keen to start building apps in .Net Core, the best way is to start with a shell project in .Net Core in Visual Studio.

Today in this blog, we will discuss the .NET core overview.

Overview of .NET core

ASP.NET is a web development platform, which gives a programming version, a complete software program infrastructure, and various offerings required to build up robust internet packages for computers, as well as cell gadgets.

ASP.NET works on the pinnacle of the HTTP protocol and makes use of the HTTP commands and guidelines to set a browser-to-server bilateral communique and cooperation.

Asp.Net is part of the Microsoft .Net platform. Asp.Net packages are compiled codes, written the usage of the extensible and reusable components or gadgets present within the .NET framework. Those codes can use the whole hierarchy of classes in the .NET framework.

Let’s see some major features of ASP.NET in detail to build a better application.

Overall performance is continually a critical characteristic for any of the applications or software. Due to its ASP.NEt middle and kestrel internet server, it’s remarked because the fastest and short net application framework is to be had within the market. Because of its new kestrel web server, it's miles more speedy and lightweight. Also, it has the advantage of asynchronous programming models. All other such things as python, java, JSP, PHP use an interpreter. But, compilers are quicker in comparison to interpreters. Compilers take all the code and assemble it at a time. So it's miles fast because asp.Net uses compiler-based total generation.

As we say it supports cross-platform means it supports Windows, macOS, and Linux. So if we create an ASP.NET application then we can directly deploy it on these platforms.

Asynchronous programming styles at the moment are carried out in ASP.NET frameworks classes and third-birthday celebration libraries.  Why asp.Net is faster, because of its wide use of asynchronous styles in kestrel frameworks. But, a maximum of the programs spend lots of time anticipating database queries, net services name, and its input-output operations to finish.

If we are creating the application then we will use IDE i.e visual studio. It provides a rich development environment by which we can easily drag and drop the components (radio buttons, checkboxes, etc.) and create the application.

The framework is language independent that is developers can use various languages like C#. So it’s easy for a developer to make its application by language which they know. We can create a dynamic web application using any of the languages.

Sockets are used to create client – server-based Applications. By socket normally we can create web-based client-server applications. These provide back and forth communication of the browser.

NET supports a very great feature that is ACTION FILTERS. These filters are used to implement error handling, authorization, caching, or any custom logic which we would like to implement. There is a logic been implemented which will be executed before and after controller action. To implement this logic Action filters are used.

We host the net utility and it can be accessed from anywhere globally. So language, date and time format, quantity format, the currency must be exclusive for exceptional areas or countries. Asp.Net supports globalization so that extraordinary countries’ clients or humans also can recognize and they can get the right of entry to this application. Asp.Net customizes our software for one-of-a-kind languages with the help of aid files. These files act as a principal repository wherein all the texts are placed.

As it helps the .Net framework so it's going to provide safety for our software. Applications have their identity, so earlier than strolling this .Net will test the identity of those objects. It'll additionally take a look at the running device safety. Due to its pre-utility configuration and feature of integrated windows authentication, our evolved software is secure and at ease. With integrated windows authentication and consistent with-utility configuration, your programs are safe and secured.

It provides support for HTML5 form types. There the new controls are available in HTML5 like email, URL, Number, RNGE, Date pickers (week, date, month, time, DateTime-local, etc.), color, and search.

This includes ASP.NET web forms. HTTP services are easily consumed and built with the help of ASP.NET Web API.

In this blog, we will discuss the Top Features of ASP.NET



Features of ASP.NET

ASP.NET versions are the different releases of the ASP.NET framework shipped over time beginning from 2002 till date, the framework has stepped forward extensively from its first ASPNET version consisting of various and really interesting capabilities delivered over time, which made the layout and improvement of net applications easier and quicker and with the different versions it progressed its website protection enforcing specific protocols for information encryption.

.NET comprises various versions, following are the top 13 ASP.NET Versions as given below.

This is the very first version of ASP.NET introduced in 2002. The 1st version was introduced along with Visual Studio.net. It was based on object-oriented programming and supported inheritance, polymorphism and others, type safety, and DLL Class Libraries. These class libraries helped in building more robust web applications with more features than simple HTML rendering.

The second version was introduced in 2003. This release was primarily targeted for support for ODBC and the database. This feature was used by mobile application developers for better web rendering. Another feature introduced with this release was automatic input validation. One of the main features of the ASP.NET framework is the security it provides. Any site in ASP.NET has security aspects as Authentication, Authorization, Confidentiality, and Integrity. The use of authentication is the process of checking if the user can access the web page while authorization is the process of defining which parts of the web page, the user can access. This authentication in ASP.NET can be done in four ways and Custom Authentication.

The third release introduced in 2005 was a significant development in previous versions with many new features. In ASP.NET 2005, there can be different data controls like Grid View, Form View, and Details View plus navigation controls. This release also introduced Master Pages, Themes, skins, web parts, and many more. It also supported 64-bit processors and full pre-compilation.

The ASP.NET 3.0 was released in the year 2006, with very important features as the Windows Presentation Foundation, Windows Workflow Foundation, Windows Communication Foundation using which ASP.NET websites can be hosted, and Windows CardSpace, which uses APS.NET for login roles.

The 3.5 version was released with Visual Studio 2008 and Windows Server 2008. This version came with support for LINQ and inbuilt ASP.NET AJAX. It also included more intuitive data controls such as ListView, Data Pager, etc. This version was used many to improve the user experience.

The Visual Studio 2008 Service Pack 1 included this release. The significant feature included support for maintaining browser history in a website developed using the ASP.NET AJAX application. Also, it included a feature of combining multiple JavaScript files into one for the sake of easier download.

Introduced in 2010, it includes features like Meta Data and Meta Description added in the Page Class of the aspx page, which helps in improving the search of your website on the internet making it SEO friendly. This version also introduced the parallel extensions to support parallel computing used in multi-core distributed systems.

The ASP.NET 4.5 version was shipped with Visual Studio 2012 version. It has some very exciting versions making the developed websites more scalable and faster with innovative data controls and easy-to-use validations.

The visible studio 2008 carrier p.C. 1 protected this release. The sizeable feature protected aid for retaining browser records in a website advanced the use of the  asp.Net ajax software. Additionally, it protected a feature of combining a couple of javascript documents into one for the sake of a less complicated download.

Introduced with the visible studio 2015 it has entity framework model 7. This model presents http/2 assist while walking on home windows 10. It additionally gives API with async calls making it thread-secure. Http/2 is a chief alternate release over the usual HTTP protocol used in the international huge net. The modifications in internet APIs also make this launch greater thrilling and are used till now by using the builders. The culture info.Current culture and culture info. The current cultural properties of the Thread class can be examined and written as nicely.

Shipped in the year 2017, it provides support for TLS protocols, it also included windows 10 update. The TLS (Transport Layer Security) protocols primarily provide privacy and data integrity between the communicating parties. Many applications such as Web Browsing, Instant Messaging, Voice Over IP use the TLS protocol service.

This version was shipped with the Windows 10 Fall Creators Update. The main feature of this release was the support for the SHA -2 (Secure Hash Algorithm). With support for TLS in version 4.7 and SHA-2 in version 4.8, the web applications now become more secure as they use cryptographic Hash Functions in data encryption.

The 4. Eight models of the ASP.NET is the modern-day version of the framework launched in 2019. This version blanketed upgrades over jit and NGEN compilers. This release presents enhancements for WCF offerings, also large improvements over the web bureaucracy, and automation upgrades for WPF. This version offers aid for updates in the ZLIB, a facts compression library. Asp.Net four.8 presents inbuilt features for compression and decompression of the files.

Some of the models supported by ASP.NET are:

NET Web Forms: This is a framework for building modular web pages, UI for these pages is processed at the server-side.

NET MVC: Helps in building web pages using a model–view–controller design pattern.

NET Web Pages: This is the framework that adds dynamic code and data access logic directly inside the HTML tags.

NET Web API: Introduced to build web API using the .NET framework.

ASP.NET Versions

ASP.NET Framework is a platform for web development, which gives a programming model, all-inclusive software infrastructure, and several services that had to create strong net packages for non-public computer systems for all cellular gadgets. It operates on all the HTTP protocols and utilizes the commands of HTTP and strategies to set up reciprocal communique from the browser to the server and collaboration. It's miles a part of Microsoft.Internet platform as ASP.NETt programs are gathered codes generated utilizing the extendable and reusable factors or objects existing inside the ASP.NET framework. These codes may be utilized in the whole hierarchy of levels in it. For instance, ASP.NET application codes will be produced within the following languages which include c#, j#, JScript, and visible simple. It could also be applied to generate reciprocated and net applications operated through information throughout the internet. It contains ample controls like the buttons, text bins, and labels for compiling, configuring, and managing the code to build HTML pages.

It elongates from the model of communication, which is driven through the event to the web applications. It works as a browser submits a form on the web to the server web, and it returns a complete page of mark up or the HTML page in answer. Then, every user activity from the end of clients is sent to the server for the stately procedure. Finally, the procedure of server the client action output and provokes the results.

Presently, a stateless protocol is HTTP. It assists in saving the data concerning the status of the application, which comprises of Page state and Session state. The page state is the client state, for example, the content of numerous input areas in the web form. The session state is the combined information gathered from numerous pages the user hit and worked with, for example, the comprehensive session state.

Here is an example to clarify the concept as the user adds the product in the shopping cart along with all the products added to the cart through the product page along with their prices mentioned differently on other pages, then goes to the cart for total pricing. That much information is only be tracked through HTTP from numerous pages. Both the session state and server end infrastructure tracks the data gathered globally in one session.

The .Net framework could also be utilized to build both applications based on Form and Web. In addition, web services can be developed employing the .Net framework.

Advantages and Disadvantages of ASP.NET Framework

The advantages and disadvantages of ASP.NET Framework:

Comprises of some of the unique characteristics

Enhanced methods should be for the security of applications.

Documentation is not precisely up to the mark.

NET Core is not good enough as certain fundamental things such as Data Access might not provide you with an assumed hundred percent.

Porting ASP applications from one server to another is costly.

ASP.NET Framework

I have heard about "principal based security", "role based security", "component centric security", and in .NET, I get to know that the Code Access Security (CAS) is kind of a "origin based security". So are there any other security models? And what technically do they mean? Could someone give me some explanations, or point me to some reference? 

How many kinds of "Security Models" are there?

I have an asp .net core web api which uses JWT to authenticate the user. I want to allow 2 ways to access it

React web app, I will have a react web app that will be the UI and of course will make requests to the api, in that I will store the jwt as an http only cookie.

Open api, the user can get a token and make requests via postman for example to my api, in that I will use Authorization Bearer token in the headers.

My question is, what is the best practice to do such a thing, I read some solutions like creating a middleware that will transfer the cookie to a header etc. But I really want to know what is the most recommended approach here?

Authenticate JWT from cookie and from Authorization bearer

Sometimes adding a WCF Service Reference generates an empty reference.cs and I cannot reference the service anywhere in the project.

Sometimes adding a WCF Service Reference generates an empty reference.cs

Microsoft now has .NET Core, .NET Framework and Xamarin (Mono) in its family.

It seems to be a lot of overlap here. What's the difference between these types of .NET Platforms? When should I choose to use .NET Core in my project, instead of .NET Framework or Xamarin?

What's the difference between .NET Core, .NET Framework, and Xamarin?

Can't find anything relevant about Entity Framework/MySQL on Google so I'm hoping someone knows about it. 

Using MySQL with Entity Framework

I'm trying to understand if there's a way to know if a notification is correctly sent to the Sentry cloud. The reason is to show to the user the feedback.

SentryId id = SentrySdk.CaptureException(ex);


and I don't see any exception or notification fired if the notification is sent or not (eg: no internet connection) to the cloud.

if it fails id will be equal to Guid.Empty. If it succeeded it will have a non-empty Guid. SentryId is a thin wrapper struct around Guid and has an implicit operator to Guid.

As for logging. Sentry has the concept of a Diagnostic Logger that should allow you to capture more detail on those failures

"Exception succesfully sent to server" event

  Recently in an official .NET Framework Blog It become introduced that .NET Core is going open source. 

  Mockingly, the author mentions that what .Net middle is might be defined within the subsequent put up.

What is ".NET Core"?

We have got an EXE and a DLL that reads/writes to an sq. Server database. The EXE and DLL run on the user's computer.

We would love to hook up with sq. Server database the usage of included protection, but not with the person's home windows identification, as a substitute with a home windows service account. In this manner, we don't want to provide the customers write get entry to to the database.

Integrated security requires that the SQL Server is running on the same computer as IIS and that all application users are on the same domain so that their credentials are available to IIS. The following areas of the application need to be configured:

Configure the ASP.NET application so that Integrated Windows Authentication is enabled and Anonymous Access is disabled.

The web.config file establishes the authentication mode that the application uses and that the application will run as or impersonate the user. Add the following elements to the web.config file:

SQL Server Integrated Security with a service account not the user's account

I'm seeking to one hundred% recognize the styles of structure in the. Internet global. The repository's most important code of the repository sample as far as I realize is commonly created inside the infrastructure layer, for facts get entry to, no longer best to databases but other cases as properly. Nowadays, I have the most effective visible it being used to get right of entry to to the database, however, I would like to look if feasible, multiple different examples for whilst the usage of a repository magnificence.

Proper now, for example, I am building an application that does HTTP requests to multiple different APIs. I have a website/center layer and an infrastructure layer. What will be the first-class exercise in this case for the HTTP requests class? Need to there be repositories for the HTTP requests verbal exchange training? Or is there some other pattern to comply with within this situation?

If possible and someone ought to give some greater distinct cloth on this subject I'd be thankful. I've searched a lot and all I'm able to discover is constantly the same database simplest related repository get entry to.

Not sure what is the best practices for this kind of a usecase, but recently I have build something similar. So basically I have folder named externalRepositories inside Infrastructure project which contains mainly three things (per host):

SomeHostHttpClient - maybe not necessarily in your case, but I'm using it for authentication, retries in case of 401/403 and logs requests/responses

SomeHostExternalRepository - handles api requests for a host, checks the response and deserializes object.

SomeHostMappingService - used to map from response dto to entity with additional requests to db for references and so on. Probably this should be inside external repository as private merhods and repo should return entities, I just wanted to separate these two by their responsibilities. But now it introduces some confusion and additional knowledge of implementation

Not saying that it is the correct solution, just sharing my experience within this topic.

.NET Repository Pattern and Http Requests

I have some code that makes a name to a 3rd-birthday party web carrier this is secured the usage of x.509 certifications.

If I name the code without delay (the usage of a unit take a look at) it works without any troubles.

Whilst deployed, this code might be called via a WCF service. I have introduced a 2d unit take a look at that calls the WCF service, however, this fails with a cryptographic exception, the message "keyset does no longer exist" when I came away on the 1/3-birthday celebration web service.

I presume that that is because my WCF provider will be trying to name the 1/3-birthday celebration web service the usage of a specific person than myself.

Cryptographic Exception 'Keyset does not exist', but only through WCF

I am used to growing a. Internet framework console application and exposing an upload(int x, int y) characteristic thru a WCF service from scratch with magnificence library (.Internet framework). I then use the console application to proxy name this characteristic inside the server.

However, if I exploit console app (.Internet center) and a category library (.Net core) the machine. The service model isn't available. I've completed a few googling but I have not found out what "replaces" WCF in this example.

How do I disclose an add(int x, int y) feature within a category library to a console software all inside? Internet core? I see gadget.Servicemodel.Net, and when you consider that this is attempting to be a moving platform do I ought to create a restful carrier?

What replaces WCF in .Net Core?

I get the error below when looking to use gitversion with AWS code built in a . Internet framework wcf task.

"it looks like the branch being examined is an indifferent head pointing to dedicate '1fa20bd'. Without a right branch call, gitversion can't decide the construct version"

I am the usage of 'full clone' within the code build motion

Does Git Version support in AWS Code Build?

I have a big pdf record which I need to split into a couple of pdfs or chunks before I upload to the server(every other WCF carrier). I've approached to send massive files(>2 Mb) to the server with the aid of splitting them more than one pdfs or one pdf into chunks. Can anyone tell me this is a way to attain? I found the articles the use iTextSharp however it is a deprecated one. I do not use certified ones. Will we have any viable manner to obtain this?

I've followed the following article. However, they've used iTextSharp that is a deprecated one.

Split large PDF file in to multiple pdfs in C#

I have a simple internet provider call, generated using a . Internet (c#) 2. Zero windows app, through the net provider proxy generated via visual studio, for a web carrier additionally written in c# (2. Zero). This has labored for numerous years and continues to accomplish that on the dozen or so locations where it's far running.

The URL of the web provider makes use of SSL (HTTPS://) -- but this has been running for a long time (and maintains to do so) from many different locations.
