linq to object - Method not found

I am trying to use a simple LINQ to Objects query.

When I try to run my application I get the message:

System.InvalidOperationException was unhandled
  Message="An error occurred creating the form. See Exception.InnerException for details.  The error is: Method not found: 'Void sharatTashlumimWS.paymentDetailsManager.set_ReleaseDate(System.Da开发者_如何学编程teTime)'."
  Source="WindowsApplication1"

If I put this code in an ASP application it's run good.

My linq statement is:

Dim query = From m In movies Select m

---

Look at the InnerException

InnerException: System.MissingMethodException
       Message="Method not found: 'Void sharatTashlumimWS.paymentDetailsManager.set_ReleaseDate(System.DateTime)'."
       Source="WindowsApplication1"

Based on the exception given, it looks like it's never even getting to your query -- something is going wrong in setting up Form1, probably in constructing the table of movies.
