Unable to launch Visual Studio because the port is in use

I was developing happily using Visual Studio 2010 .Suddenly it started sowing an error message reading 'Unable to launch Visual Studio because the port 1160 is in use'. I was not sure why it happened suddenly. Whenever I hit F5 it shows this.

I have tried different ways to get rid of this .
Restarted VS
Changed the port in IIS

But nothing worked . Finally found a solution as given below:

Solution

Simply end all Webdev.WebServer.exe processes  . This error happens when one of the visual studio processes (webdev.webserver.exe) is still running and locked. The webdev.webserver process(s) should end when you close your browser or app but for some reason it dont.

Next to the clock, in the task bar  there's a list of icons which can be seen  if you click on the triangle icon that is next to the flag icon. Find  an icon with tooltip "ASP.net development server - port ###". Right click and select "stop"!




Otherwise you can start the task manager and find for the ASp.Net development server process and select 'End Now'

Both options will do the trick!!

Happy Coding !!
