"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Check your project settings. You're using a library with the wrong .NET version. Either you're building your migrated project in a newer version, or you load a library dynamically without checking its .NET version.
