Feature: Make `[assembly: Attribute]` work with virtual methods that don't have an override about aspect-injector

[pamidur]

Sorry for delay,
this is interesting feature request that was actually requested several times by now.
Could you please drop a source code sample where it does not work with comments where it should work? It would help immensely!

Third party NuGet Assembly1

namespace Assembly1;

public class Base
{
    public virtual Foo()
    {
    }
}

My project Assembly2

MethodTimerAttribute.cs

using AspectInjector.Broker;
using System;

namespace Assembly2
{
    [Aspect(Scope.Global)]
    [Injection(typeof(MethodTimerAttribute))]
    [AttributeUsage(AttributeTargets.Assembly | AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
    public class MethodTimerAttribute : Attribute
    {
        [Advice(Kind.Before)]
        public void OnEntry([Argument(Source.Name)] string methodName, [Argument(Source.Type)] Type declaringType)
        {
            Console.WriteLine($"Before {declaringType}.{methodName}");
        }

        [Advice(Kind.After)]
        public void OnExit([Argument(Source.Name)] string methodName, [Argument(Source.Type)] Type declaringType)
        {
            Console.WriteLine($"After {declaringType}.{methodName}");
        }
    }
}

Program.cs

namespace Assembly2;

[assembly: MethodTimer]

var ok = new DerivedMethodTimerWorking();
ok.Foo(); // MethodTimer is working

var notOk = new DerivedMethodTimerNotWorking();
notOk.Foo();  // MethodTimer is not working

Derived.cs

namespace Assembly2;

class DerivedMethodTimerWorking : Assembly1.Base
{
    public override Foo()
    {
    }
}

class DerivedMethodTimerNotWorking : Assembly1.Base
{
    public Bar()
    {
    }
}

I would like that MethodTimer would work in DerivedMethodTimerNotWorking.Foo even though it is not overriden in Assembly2 and the virtual method source is in NuGet Assembly1

What I tried to do was to add public override Foo() to DerivedMethodTimerNotWorking with Mono.Cecil but it doesn't compile / build in my Blazor project.
