I have created a c# project and then added another project to it.the issue is the first project only consists of class libraries.while the second project has a console application where i have called main().I now want to remove the 2nd project and call main() in one of the class libraries. but when i do this every time i get error no valid main.

What I have tried:

" call main() in one of the class libraries" class libraries do not have a "main" function for you to call and even if they did, you don't call the main function at all.

In order to be an EXE file, an assembly must contain one (and one only) Main function which is declared as static - if it does not have such, it is not a valid executable, it is a class library and cannot be executed (it should have a .DLL extension instead of .EXE).
You cannot execute DLL files directly: you need to set your EXE file project (the one with the Main method) as the "Startup project" for the solution.
Open the Solution Explorer pane, and right click the project containing the Main method.
From the pop-up menu, select "Set as Startup Project". The project name will be shown as bold.
