Visual Studio 2017 How to create a individual setup grouping 3 applications .net

Hello,

How is it possible to create only one setup.exe file which regroups 3 applications vbnet?

I know how to do this for a separate application, via publish.

Here I have an application AppA which starts an application AppB which starts an application AppC. They are all Windows applications forms.

I tried to group these 3 applications into a solution, but I can't see where I can create an setup.exe for a solution.

Any idea? Do I have to use an external software? Which one?

Thanks

Pierre
