After upgrading (or trying to upgrade) to BugNet 1.6 I get the following error. I have searched the forums here and internet to no avail. I have made sure that .NET version 4.5 and 4.5.1 are installed, BugNet is using IIS App pool with .NET 4.0 selected. Cannot find what is causing this error.

Assistance would be appreciated
