The error message most likely means you're running an older version of the .NET framework than the DLL you are trying to load. wwdotnetbridge (latest version) is compiled for .NET 4.5.2 which means it can run any 4.x version. But if you try to load an assembly created for 4.6 or you are running the 4.0 version of the runtime (or worse the 4.0 client runtime) the CLR will fail to load.

Make sure you have at least 4.5.2 installed.
