sqlConnection.ServerVersion' threw an exception of type 'System.InvalidOperationException'

NOTE: I'm running this on my dev machine. When it runs on live web server, all is well. It is unique to my system.

NOTE: recently upgraded from Sql Server 2005 to 2008

This could possibly be caused by a difference in your web.config between the live server and your dev machine. Have you checked that the connection string is properly specified?

Found problem. There was a space in the front of the connection string.
