Entity framework 4 - Table with Identity column addition

votes

I have a table defined in a SQL Server database as follows

Columns

  1. MID Int foreign Key
  2. MRUOMID Int foreign Key

All columns in this table are foreign keys and referring to other entities.

I wish to add an Identity column to this table. If I do so and update the EDMX model from the database, I get the following error.

problem in mapping fragments starting at 7462. You must specify mapping for all key properties.

I need an identity column to be added which I can refer to in my Entity model further.

Please let me know on this issues.

Thanks.

While updating, make sure you include the foreign keys too.
