Can't perform Create, Update or Delete operations on Table because it has no primary key

Question

I\'ve been trying to insert row in the table having an identity column RequestID (which is primary key as well)

    HelpdeskLog logEntry = new HelpdeskLog {          


        

Answer 1

As the the table has the primary key in SQL Server, re-addthe table in the linq2sql designer.

If that were not the case, you can configure which properties are part of the primary key by hand on the designer.
