Visual Studio Debugging/Building

Question

I have a solution that has a plain old asp.net website and a winforms app.

I have the winforms app set as my startup application.

When I press (CTRL+)F5, it just runs the app without building. So, my changes aren't built into the program.

What should I do to fix this?

EDIT

I don't want to have to go to the build menu and then debug. I want a single step.

EDIT 2

This is VS 2008 SP1

Answer 1

I had to go into the properties for my solution and select the projects that I want to include during builds.
