AddressAlreadyInUse Exception

I am new in learning C# Service Client Application. I made one project, the problem is that whenever I run it it shows the following exception:

Address Already in use Exception: HTTP could not register URL http://+:80/Temporary_Listen_Addresses/6c2d8437-020f-4267-b93b-450ef3546b04/ because TCP port 80 is being used by another application.

But the same project works fine in my sister's laptop.I don't know what is the reason but I am somehow sure that there is nothing wrong with the project.


Your port 80 is in use. Another application on your computer is using it.

Maybe you are running a webserver?

If you are, maybe your project should be hosted there instead. If not, you can simply use another port.

Actually the problem was that Skype was running on this port.After ending Skype process,the exception disappeared
