Try to fix rewrite for self file extension method

[builder-main]

Hi, let's try to make a rewriter for extension methods. It would allow to avoid ambiguous call compilation errors :

public static class SomeClass {

  public static void MyExtension(this string myString){  ... }

  public static void MyMethod(){  "someValue".MyExtension() } //Will cause an ambiguous call in the compiler

  public static void MyMethod(){  MyExtension("someValue") } //This works and is the current workaround.
}

Thanks - I think extensions are also part of other feature. Off top of my head there were some more issues with that unfortunately.

I think especially for rewritten code where YourType would end up YourType__Patched_ and extension method will complain.

We could probably cast it to (ProperType)(dynamic)variable. That's a hack for compiler as your variable is still of old type, same approach is used for something else already (I think for 'this' rewritting)

Is it not possible for rewriting extension methods yet now? Currently I’m working with one ECS framework of Unity, and it uses extension method almost everywhere :(

sorry, I've not had a chance to get to it. I could point you in the right direction if you want to give that a try
