I'm afraid that .NET Reflector cannot work with this assembly as it appears to have been protected with a tool that's made it so that decompilers cannot open it.
Apologies as I realize this is not the answer you were hoping for-please let me know if you have any further questions!

But you can explain detail that tool develop by Microsoft Visual C# so why .NET Reflector can't open it?
