Mixed mode assembly is built against version 'v1.1.4322'

Question

Hello! i've included a directX player in c# .net 4.0 app that is included here ( answer2 ) . The problem is that when i try to initialize the object ( i.e. Player mPlayer=new Player()) this error occurs :

Mixed mode assembly is built against version 'v1.1.4322' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

Anyone knows what it can be?

Answer 1

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.
