    I have developed an application using Entity Framework, SQL Server 2000, VS 2008 and Enterprise Library.

    It works absolutely fine locally but when I deploy the project to our test environment, I am getting the following error:

    "Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information."

    I couldn't find where this error message comes from and why? is it from my application or from database?

    Any clue?

    Thanks,
    Any clue?

    I believe I resolved this issue but I don't remember how exactly!

    I think there was a wrong assembly copied over to my test environment.
