A null reference exception is almost always something to do with your
code. They are also relatively easy to debug, with access to the code.
All you have to do is look in the debugger where the program stopped
and see what's null and why.

Of course, since you didn't post any code, never mind a
concise-but-complete code example that reliably reproduces the problem,
there would be no way for anyone else to suggest what might be wrong.
But you should be able to figure it out yourself.

If you're unable to, for anyone else to provide any specific information
you'd need to provide more information than you have so far. Such as
the code example I mentioned above.
