Answer 1

Problem : you are running the same project/program always.

Solution 1:

Select the project you want to run.
Right click on it.
Select Debug Option
Select Start new instance.

Solution 2:

Select the project you want to run.
Right Click on it.
Select Set as startup project.
Now run the project.

EDIT: when you right click on the Project( not on Solution) you will get following ContextMenu from there you can find above mentioned options to proceed further.

Answer 2

Note that you don't have 2 different programs open in the tabs but instead 2 different files each one belonging to a different project. When you hit run / F5 Visual Studio doesn't decide what to run based on the selected file. Instead it will attempt to run the project which is currently labeled as the start up project. Hence simply changing the active tab won't have any effect on what is run.

If you want to change the project which is being run then right click on the target project and select "Set as Startup Project". The project which is currently the startup project will be displayed in bolt text

Answer 3

Right click on the project that outputs "hello cat" and click "Set as StartUp Project".

In Visual Studio a solution may hold none or many runable applications. The project with the bolded text is the project that will run when you click "Start".
