Set a [Breakpoint](https://msdn.microsoft.com/en-us/library/vstudio/k80ex6de(v=vs.100).aspx) and check what is null. There is no difference between breakpoints in C# and VB.Net – Reza Aghaei Oct 29 '15 at 00:13
@RezaAghaei Thanks it worked. I was just passing a silly null :) – Muhammad Noman Aslam Oct 29 '15 at 00:24
