Error: 1. Solution exception:Object reference not set to an instance of an object.

Hi Elcin,

first of all thank you for the @it.
I tried to use it but I alway get errors, so I downloaded your example file from the hydrashare http://hydrashare.github.io/hydra/viewer?owner=elcinertugrul&fo...
but it gives me the same error, I have the newest .NET installed
do you have any sugessions what can be the problem ?

Kind regards

Peter
