A property is supposed to mimic something like a field in that it typically should perform little (or at least very quick) work. Otherwise, you have to create an object of that type or use the standard reflection API solution. In trying to accomplish with as little code as possible, getter and async feels like the perfect combination. The copy that gets returned will therefore have an OpenGL object name that has been Thanks for contributing an answer to Stack Overflow! To call a function you must use the following protocol: first, the function to be called is pushed onto the stack; then, the arguments to the function are pushed in direct order; that is, the first argument is pushed first.

I appreciate the feedback on my answer; I'd really love for somebody to provide an example where this deadlocks so I can see it in action, This sounded right for my situation, but when I added GetAwaiter().GetResult() the whole app locked up never to be used again (instant 100% deadlock) I can't fully explain that, but if I can think of a small sample case I'll do it.

(good old async delegates). public class myClass { public void Foo(T item) { Console.WriteLine(typeof(T).Name); } } Then you can implement an Extension method like: Consider the following sample code - inside the Example() method, what's the most concise way to invoke GenericMethod() using the Type stored in the myType variable? Calling a generic method with a type parameter known only at runtime can be greatly simplified by using a dynamic type instead of the reflection API. If you. Well, I agree for common uses of reflection. If you have a long-running property its much better to write it as a method so the caller knows it's a more complex body of work.
