'.NET: Introducing Generics in the CLR,'bloggerForm','scrollbars=no,width=475,height=300,top=175,left=75,status=yes,resizable=yes: "Generics are an extension of the CLR type system that allow developers to define types for which certain details are left unspecified. These details are specified when the code is referenced by consumer code, making for enhanced flexibility. Jason Clark explains how."

How do I debug a custom action/installer class?

You can use one of the following methods:
Add a call in your code to System.Diagnostics.Debugger.Launch. This method opens Just-In-Time debugging and allows you to attach a new debugger to your code.
Add a call in your code to MessageBox.Show("Debug Me"). When the message box is shown, use Visual Studio to attach to the MessageBox process. Then place breaks (for Visual C# projects) or stops (for Visual Basic projects) in the code.
Set your debugging preferences to start InstallUtil.exe (which is located in \winnt\Microsoft.net\Framework\version) and pass it your assembly as a parameter. When you press F5, you hit your breakpoint. InstallUtil.exe will run your custom actions the same way that MSI does.
