Can I redirect .NET method calls to a new method at runtime?

Question

Suppose I have the following .NET classes:

public class C
{
    public void M()
    {
        ....
    }
}

and

public class

Microsoft has created a managed equivalent to Detours called Moles. The only thing I'm not sure of is the licensing; it is intended for testing (as part of Pex).

Dependency injection requires modifying the source; PostSharp requires modifying the binary; but Moles can be done dynamically at runtime.
