You are describing making a class library project. Compiling is the right term. We thought you meant compiling a standalone program, which is certainly possible without the command line interface.

You can do DLL's too but it (as described above) you have to either open an existing DLL project or tamper around with the wizards. Its not an add-in or anything like that its more like revealing a feature that was undocumented

Assuming that its legal to do the wizard thing, then you only have to copy them once and then run the wizards as and when needed. Assuming its legal of course.

And since MSDN tells you how to create wizards yourself, then just make one identical to the packaged one et voila.
