C/C++ is nothing like C#. Beyond the most basic syntax level, they just don't compare.
Hmm well then that might be a problem as well. One of the reasons I was looking forward to learning C# was because it's easy-to-use with graphics and I thought it would be similar to C++ (which I'm also using for something else).
I also like making games/tools from scratch - no engines or wrappers like Blitz languages.
