I think it's way better to use something like:
	Assembly a = Assembly.LoadWithPartialName ("System.Data");
	Type t = a.GetType ("System.Data.SqlClient.SqlConnection");
	...
because I guess your code is going to break with the next (or different
versions) of the CLR where the exact same version may not be available.
