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 I was using Windows 8 and Windows Firewall was blocking WebDev.WebServer.EXE

So I went to the settings of Windows Firewall > Allow an app through Windows Firewall > Add new and browse to C:\Program Files (x86)\Common Files\Microsoft Shared\DevServer\11.0 Then select WebDev.WebServer to allow.
