Yeah in C# it has quite a few uses.

I'm working on a background fun project where there's a base class that is for olde style CPU emulation. Where you can derive a class from the base class and essentially design 8bit style CPUs.

I have a separate class as a generic Assembler that will work with any of the created CPUs. But, to be able to do that I need to be able to get information about instructions, arguments, opcodes, registers etc from the derived class.

So the assembler is instantiated with Assembler\ and then it uses typeof to instantiate the actual CPU class being used to get all the information.

So, that's just an example of when you'd use something like this.
