    I recently updated a popular windows phone app to use many of the nice Telerik features.  It is a great improvement and people love it.  However, I have reports from a few people that the app is no longer as stable as it used to be, which has me worried.

    Here is a stack trace I got via my error reporting mechanism this morning.  I am wondering what might cause a MethodAccessException here and how I might address this issue?  Funny, it seems the MethodAccessException was thrown during an attempt to throw some other type of exception.


    Type: System.MethodAccessException

    Message: Attempt to access the method failed: System.ThrowHelper.ThrowInvalidOperationException(System.ExceptionResource)

    Hello Paul,

    Thanks for writing and for choosing RadControls for Windows Phone.

    From the stack trace it is clear that this issue happens in our list box control. However, it will be difficult for us to determine the reason for the exception without reproducing it on our side. We have never received reports for similar problems in DataBoundListBox and therefore it will be great if you manage to gather some more information about the scenario in which the exception occurs and share it with us.

    Let us know if we can further assist you or in case you have any questions.

    Thanks for your time.

    All the best,
    the Telerik team
