Answer 1

As the error suggests, you cannot run a class library type project. Check properties of your project and see what type of application it is.

Answer 2

To fix this issue, do these steps:

Right click the Project name in Solution Explorer of Visual Studio Select Set as StartUp Project from the popup menu Re-run your project, it should work!

If it did not work, be sure that you have set your start page. If your project is C# Windows Application or C# Console Application, try this:

Right click the Project name in Solution Explorer of Visual Studio Select Properties Select Application tab In Output type drop box, select the correct application type of your project Re-run your project.

Change the Output Type under the Project > Properties to that of a “Class Library”. By default, this setting may have been set to a “Console Application”
