ASP.NET : "Only one usage of each socket address (protocol/network address/port) is normally permitted"

You might get an error "Only one usage of each socket address (protocol/network address/port) is normally permitted" when trying to run an ASP.NET application. This might happen when you either have muliple apps using the same port in Casinini web server or when you have many ASP.NET apps running simultaneously.

For a workaround, use the following steps:
1. Close the ASP.NET solution in Visual Studio.
2. Navigate to the folder containing the Project file of the ASP.NET application.
3. Right click on the Project file of the ASP.NET project (the one with extension (.csproj))
4. Do a Find for "" tag. Change the value to "False".
5. Rename the "" also with a different number if you wish.
6. Save the file and close it.

Now open the ASP.NET solution again and try to run your app. You'll now be able to run the application without the error quoted above.

Cheers!
