How to send a null value to a not null column in ASP.NET with LINQ

my problem is this:

• I have a table in SQL Server that have a NOT NULL Column that uses a SEQUENCE as default (NEXT VALUE FOR SeqDefa), that column is not the PK from the table.
• I building a web form in ASP.NET that does a CRUD in that table, when i want to send a null value in that column to use the default in that table i get an error. that's because LINQ says that you can't send a null value to a not null column

how can i fix it?

can i get the sequence´s next value from LINQ in my form? there's another option than changing table column from not null to allowing nulls?
