Performance Tuning for .NET Core

That's where delegation comes in. You wrap each public method of Foo in another class call MyFoo and then fix the one method you care about. With C# and R# it's a simple matter of:

Create a new class

Create a private variable:

private Foo _foo

Click on _foo

Resharper menu -> Generate Code -> create Delegating members.

But you can't pass that into places that accept Foo because MyFoo isn't of the type Foo so that's a non-starter is most cases.

Secondly this code generation solution is just re-implementing inheritance again poorly and with the above mentioned limitation. I fail to see how code generating a proxy is any way better than (or significantly different from) inheritance.

Hopefully the code was written to depend on interfaces and not hard coded types.

So if you implement an interface and then use code generation to create proxy from a "parent class", congratulations you just reinvented inheritance. What's the difference?
