In the 458 build, GetConnection() contained the following code: return (IDbConnection) ((ICloneable)_templateConnection).Clone();
The built-in providers (SqlClient, OleDb, etc.) implement the ICloneable interface. There a some 3rd party providers that do not. The exception you're seeing is most likely being caused by your provider not implementing ICloneable.
