When trying to pass a whole project to another PC, when I run it, I get this error! Already try to change the port in Properties / Web and still continue with the same problem.
Along with your .SLN file there is usually a hidden folder called .vs , delete it.
To do so, follow these steps:
In this folder, IIS Express configurations are saved, which when they move from one computer to another, can cause the problem you are having.
Delete or rename the folder that is automatically created from IISExpress in C: \ Users \ YourName \ Documents \ IISExpress When you run the application, Visual Studio recreates it and it should work for you
