C# 7 Local Functions: are attributes / aspects allowed?

Question

C# 7 introduced local functions (which is great!). Suppose I have the following code:

    using System;
    using PostSharp.Aspects;

    namespace AspectCS7
    {
        class Program
        {
            private static void Main()
            {
                [MyAspect]            
                void LocalFunction()
                {
                    Console.WriteLine("Hello Aspect!");
                }

                LocalFunction();
            }
        }

        [Serializable]
        public class MyAspect : OnMethodBoundaryAspect
        {
            public override void OnEntry(MethodExecutionArgs args)
            {
                Console.WriteLine("Entering Aspect");
            }
        }
    }

This code shows compile-time errors. Is it possible to apply attributes to local functions?

Answer 1

Attributes were allowed on local functions at one point. There are some examples on the web of local functions using attributes, however they're not allowed anymore.

Update: Here is an ongoing discussion on this topic: https://github.com/dotnet/csharplang/issues/794.
