Execute a method of a different namspace by dynamic code in C# winforms

Question

I am implementing a dynamic code execution in C# which allows users to write their own c# for that particular application.

I am using C# code compiler for executing the dynamic codes. The C# compiler reads the code file and construct the code in new namespace (a complete new code), compiles and runs it. In other view the base application host all these.

I have few methods that are present in host application that I want to be executed by the dynamic code. Is there any way by which the method of other namespace or application can be executed?

Could you force the author of your script to implement an interface, or you could even wrap their code with your own implementation..

Something like

public interface IMyApplication
{
      void DoSomethingInMyMainApp();
}
public interface IScriptKiddie
{
      void Init(IMyApplication app);
}

Then your l33t scripters can write

public class MyScript : IScriptKiddie //< you could emit this yourself
{

     public void Init(IMyApplication app) //<could emit this yourself if scripter knows app keyword
     {
          app.DoSomethingInMyMainApp();
     }
}

and in your app you can provide a concrete implementation of IMyApplication to pass into the class when you have compiled, constructed the class then pass into Init method.
