I always get this error whem trying the "Reverse Mapping" button.
I have checked the web.config and everything seem to be right....
<add name="kobenhavn" connectionString="data source=BWWSQL;initial catalog=kobenhavn;persist security info=True;user id=kobenhavn;password=xxxxxx" providerName="System.Data.SqlClient" />
I have now tryed many times with different names, databasen and even both with VS 2008 and VS 2010...
Is this a know bug?
