This is one of the things that having a preprocessor is useful for. You could define a macro that swallows exceptions, then with a quick script add that macro to all lines.

That's a wrong approach. C# isn't C++. **Forget about header files**.
If you want the class summary, just open the **Object Browser** in Visual Studio. It will give you the signature of all the methods within your classes. |
I don't think you can do header files like you can in C++.
Check out the partial keyword for both classes and methods. I just learned about them yesterday, so I haven't really used them, but they might help you accomplish what you're trying to do. |

There are several methods, such as using the processor ID to generate an "activation key."
