Nullable field not saving null

Facing a strange problem with EF at the moment. I have a table in database with nvarchar(MAX) data type and is a nullable field. While updating the entries in the table when I assign null to this field its not saving that null, rather keeping the old value intact. But saving the empty string in it works.


Any solution or guidance will be really appreciated.

Have tried google and tried
