I solely work with web applications, so I have virtually no real experience with Windows Forms designed in .NET. I'm reading up on assemblies, and there are two types; static, which comes in .dll form, and exectuable, which comes in .exe form.

Somewhat academic question, but: How do value types like Int actually work? I've used Reflector on mscorlib to find out how System.Int32 is implemented, and it's just a Struct that inherits from System.ValueType.
