Another System.NullReferenceException #37

Open brutaldev opened 7 years ago

brutaldev commented 7 years ago

Sometimes Smocks randomly fails all Run calls and never recovers again. Changing the static method names in the Setup calls makes it works again for a while until it breaks again. Changing names back to their original makes things work again...

System.NullReferenceException : Object reference not set to an instance of an object.

Happens for me when I try mocking DateTime.Now and DateTime.Today in combination with netstandard 2.0.
