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?

.net-4.0 c#

The way I fixed this error was by changing the 'configuration' node on my app.config from this:

<startup>
   <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>

to this:

<startup useLegacyV2RuntimeActivationPolicy="true">
   <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
