Why doesn't F5 rebuild the project before running it in Visual Studio?

Question

If I press F5 , my project starts, but it does not “see” any changes that I made. I need to do a manual (re) assembly before pressing F5 to make it work.

It worked well previously. Any idea what I need to change?

Answer 1

Is it possible that you configured the "Build and Run" settings to "Never build"?

To check, follow these steps:

• In the Visual Studio IDE, open the Tools menu and click Options.
• Expand the "Projects and Solutions" heading to the left.
• Click Create and Run.
• In the “On” combo box, when the projects are out of date, make sure that you have the option “Always build” .

Answer 2

Also:

• Right-click on a solution in the solution explorer.

• Click "Properties."

• Go to Configuration Properties → Configuration on the left side of the window.

• Select the Create check box on your project line.

Answer 3

Another reason (which I had) may be dependent.

In Solution Explorer, right-click Startup Project - Build Dependencies - Project Dependencies.

If the project you are working on is not defined depending on the startup project, it will not be created when you run F5 / run.

Answer 4

Well, for some reason, all of the above solutions do not work for me, so I did the Pre-Build event (Right-click Project → Properties → Build Events), where I delete the bin and obj folder before the build.
