Does .Net 4 use the built-in MarshalByRefObject methods?

Question

I have code based on methods not on the line:

internal class MyClass : BaseClass { // should not be inlined public void DoSomething(int id) { base.Execute(id); } } public abstract class BaseClass : MarshallByRefObject { [MethodImpl(MethodImplOptions.NoInlining)] protected void Execute(params object[] args) { // does a stack walk to find signature of calling method } } 

Of course, this only works if the DoSomething method is not built-in. That is why the base class comes from MarshallByRefObject , which prevents the embedding of public methods.

This has worked so far, but I got the stack from the .Net 4 server, showing that stackwalk reached the DoSomething call.

Is .NET-inline smarter and discovers that MyClass is internal and has no chance of replacing its proxy?

The comments here indicate that you also need to specify NoOptimisation to achieve what you want.
