Why can't two methods be declared with the same signature even though their return types are different? [duplicate]

Answer 1

There's nothing from stopping you from calling your method without "capturing" the return type. There's nothing from stopping you from doing this:

myClass.MyMethod();

How will the compiler know which one to call in that case?

Edit: Adding to that, in C# 3.0, when you can use var, how will the compiler know which method you're calling when you do this:

var result = myClass.MyMethod();
