This assembly built by a runtime newer than loaded runtime

edited August 2010 in Photon Server
Im following the instructions in the Blank Photon Server Setup PDF, but receive the following error when i attempt to start the server:
2876: 16:27:53.658 - CService::OnException() - Exception: CManagedHost::RunApplicationInNewDomain() - Failed to run application: "BLBServer", "BLBServer.BLBServer" - Could not load file or assembly 'BLBServer' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

any suggestions much appreciated.


  • scratch that. I had not noticed when i created the Class Library .NET project that it had defaulted to .NET framework 4.0, needed to be 3.5
