Make DynamicMethod invokable "directly"

[TahirAhmadov]

Hi all, code like the below currently fails:

var dm = new DynamicMethod(...); // emit some IL
var type = module.DefineType(...);
var mb = type.DefineMethod(...);
mb.GetILGenerator().Emit(OpCodes.Call, dm);

type.CreateType().GetMethod(...).Invoke(...); // exception: Unable to import a global method or field from a different module

Looking at the code, there is GetMethodTokenNoLock method and it doesn't support DynamicMethod at all. Is there some underlying limitation which prevents this from being a viable scenario? If not, can it be fixed, please? :)

Currently I end up having to create a delegate, store it in a static field somewhere, and then call the delegates Invoke method - which basically calls the DynamicMethod indirectly. Not only it's make work, but it's also a delegate invocation which is probably slightly slower than a direct call the DynamicMethod.

That link is broken?

It pings the area owners of Reflection.Emit, and can be used by .NET team members and community triagers (I am the latter). I will open an issue, hope it gets more attention.

Opened #68791.
