    Is there any way to work around this issue? I am unable to seed my database.

    Thanks

    If you hit F5 enough, it will go away eventually. When the first one appears, I have been disabling that type of exception until the application has started and then restore it again.

    The exception does not appear to be causing any problems with actually running the application.
