Here are the steps
1. 'Website' Menu in your visual studio ide.
2. select 'Start Options'
3. enable 'Use Custom Server' radio button.
4. Enter any URL you desire similar to 'http://localhost:8010/MyApp'
Note1: you can use any port number not only '8010' but not designated port numbers like 8080(tcpip),25(smtp),21(ftp) etc.,
Note2: you can use any name not only 'MyApp'
This solution should work unless your WebDev.Webserver.exe is physically corrupted othewise you have to look for any other approach.
