Generally speaking, you don't - because one console doesn't share well with three apps: the inputs and outputs would get mixed up and it just wouldn't work.

However, it is pretty simple to create a "master app" that causes the other three to open.

Create a new app, and use Process.Start[^] to execute the other three, then close the "master app". If you add references to the other three projects, then the executables will be copied to the EXE folder from your master app so they are easy to find.

Solution 2

Take a look at: GitHub - Fody/Costura: Embed references as resources[^] and ILMerge is a static linker for .NET Assemblies.[^]
But these probably won't allow you to merge different solutions.

I am not trying to merge the different solutions what am trying to achieve is to be able to combine the 3 projects into one. In each of the project is a program.cs class which which I intend to rename to program1.cs, program2.cs, program3.cs and there after create a new program.cs that will refernce or link the others.

If it is a console application, make a menu and use ReadKey to get user input, then execute the code you want. If it is Winforms make a main form and run the form you want from there.
