How do I set Visual Studio to always build and debug when F5 is pressed? [duplicate]

Question

It used to do this, but now if I don't build the solution first before pressing F5, it uses the last built program.

I must have messed up a setting somewhere I think.

Answer 1

1. Open the "Tools" menu, and click "Options".

2. Expand "Projects and Solutions".

3. Click on "Build and Run" tab.

4. In the "On Run, when projects are out of date" dropdown, select "Always build".

Answer 2

You are probably working on a multi-project solution:

• Get properties of your solution (right click → Properties)
• Click on "Configuration Properties".
• Tick the "Build" check box for the project that is not compiled properly.
