The designer encountered an error while loading the table definition?

Question

I\'ve problem with Visual Studio 2012 Ultimate.

I inserted a \"Sql Server Database\", and when I try to \"Add new table\" after a while I get this problem

Answer 1

Use "SQL Server Object Explorer" instead "server explorer" but close all the database connections that appear in the server explorer.

From the SQL server object explorer add the local SQL server and that's it, works like a charm.
