title: Problem with Entity Framework after adding column to DB table
body: <p>I needed to add a new NVARCHAR column to a table in my DB. So I added the column, and then fired up Visual Studio to update the EDMX-file for the Entity Framework.</p>
  
  <p>I ran update model from database on everything, which only resulted in "data reader is incompatible"-errors. So I renamed the whole table in the DB, updated EDMX from database, renamed the table back to the original name, ran update again, and then created new function imports for all affected stored procedures. But I still get the same error:</p>
  
  <blockquote>
    <p>The data reader is incompatible with
    the specified '[Model].[Entity]'. A
    member of the type,
    '[Column]', does not have a
    corresponding column in the data
    reader with the same name.</p>
  </blockquote>
  
  <p>I've looked around a bit, and this seems to be a common error if the column name is different in the database and framework. This is however not the case, they have the same name.</p>
  
  <p>I can access the column in the code via [Entity].Context.[Column], so I don't quite see what the data reader is complaining about.</p>
  
  <p>I've run out of ideas, so any help welcome.</p>
