'Delegate 'System.Action' does not take 0 arguments.' Is this a C# compiler bug (lambdas + two projects)?

Question

Consider the code below. Looks like perfectly valid C# code right?

//Project B
using System;
public delegate void ActionSurrogate(Action addEvent);
//public          


        

Answer 1

    public static void ThisWontCompile()
        {
            ActionSurrogate b = (Action a) =>
            {
                a();
            };


        }

This will compile. Some glitch with the compiler its unable to find the Action delegate without parameters. That's why you are getting the error.

public delegate void Action();
public delegate void Action();
public delegate void Action();
public delegate void Action();
public delegate void Action();
