I am debugging codeplex simple project. I am using
- VSTS 2008
- C#
- Windows Vista x86 Enterprise.
I have not modified any code of this codeplex project, and just press F5 to run VideoPlayerWeb project.
The current issue I met with is error message —
Unable to connect to ASP.Net Development Server.
Here is my screen snapshots when clicking F5. Any ideas what is wrong?


I had this problem with VS 2010, and it was as simple as terminating the “WebDev.WebServer40.EXE” process. Although the icon was no longer showing in the system tray, the process was still running.
