In VS 2013, you get an error message when you try this:
The class frmInformation can be designed, but is not the first class in the file. Visual Studio requires that designers use the first class in the file. Move the class code so that it is the first class in the file and try loading the designer again.
There is a good chance that you get this message as well.
It's a restriction on how the VS designer works, is all. Embed your new class within Form1 or add it at the end of the file instead of the start (or better, put it in it's own file so it is easy to find)
