• Visual C# Overloading = operator

  Is it possible to use = operator to copy one object to another much like in C++ (using already created copy constructor), so if I write MyObject A = new MyObject(); MyObject B = A; A and B wouldn't point to same object but actually point to two different objects (that have the same state, but are infact different). I understand that it cannot be done OOTB because overload of = must be static method, but I'm interested is ther ...Show All

• Visual Studio Team System Possible to detect use of enum.ToString()?

  Does anyone know if it is possible to detect the use of an enum's "ToString()" method The reason I ask is because we have started obfuscating our code using Dotfuscator, and of course because that renames the enums, it plays merry hell with any use of enum.ToString()! It'd be great if FXCopy could detect such usage. Also, I guess we'd need to detect enum.Parse() and other reflection-style access. Any help would be much appreciated! ...Show All
