Unable to connect to ASP.Net Development Server issue

Question

I am debugging codeplex simple project. I am using

• VSTS 2008
• C#
• Windows Vista x86 Enterprise.

I have not modified any code

Answer 1

In my case, when I had the ASP.NET Development Server crash, one thing that worked was to change the port for the project.

I suspect what happened was when the web server crashed it did not release a lock on the port. Even though it was not running in Task Manager, something was blocking a new instance of the web server from starting again on the original port. Changing the port was a decent enough work around. I could have rebooted, but who has time for that, right?

Details: Windows 7 x64, VS2010, .NET Framework 4.0, ASP.NET web site using the built in web server to VS2010.

BTW, I would be a little cautious with replacing the WebDev.WebServerServer.EXE as suggested in other posts. If that file has been corrupted then you have bigger problems with your OS.
