We'll serialize the object, and the immediately deserialize it back to an object and then return it. This way its a brand new object (not another reference) and its an exact copy.

It's apparently something from C++, and in C# it doesn't exist. Read more about it here: http://msdn2.microsoft.com/en-us/library/ms173116.aspx Summary: While creating a new object, in its constructor, you pass in an object of the same type. The constructor will then copy the passed object into itself, making an exact copy. No idea if C++ supports this by default, unfortunatly C# doesn't. But perhaps with some reflection, you can create this yourself. I just learned this myself a few days ago, it’s called a copy constructor.
