I get an error

Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

What shall I do?

You need to add an app.Config file and set useLegacyV2RuntimeActivationPolicy to true.

This is required to use mixed mode CLR 2 assemblies in a .NET 4 application.
