title: Changing a table in DBML file throws error
body: <p>I had to add a new column to my table so I did that in the database and then I removed the table from the dbml file and readded the one with the new column. So the column I added was (_isActive bit null allowed) and this messed up my designer file. It has added a duplicate definition of some of the attributes like: private bool <em>isActive and other one as private System.Nullable @</em>_isActive; Also added additional stuff. I had to delete the designer file and reload it with old one. How should I go to make this change in the dbml file?</p>
