VS2010 Ultimate - Unable to launch ASP.NET Development Server

Question

I've worked with ASP.NET once before and had a project where it was potentially useful, so I started creating an ASP.NET website as part of a solution that contained several C# class libraries.

I'm using Visual Studio 2010 Ultimate Edition and Windows 7 Professional x64. The issue is that when I try to debug my website project, I get the following error message:

Unable to launch the ASP.NET Development Server

There's no other information (it seems a popular variant is the "port in use" error).

Interestingly, I can run single pages on the application by right-clicking on the ASPX and selecting "View in Browser". This does not allow me to debug into my breakpoints, though.

I have no clue what the problem could be. I'm running VS2010 in Administrator mode. One of the questions that popped up here suggested I uncomment the "127.0.0.1 localhost" line from my HOSTS file, which I did, and restarted VS with no luck. I also tried both setting a static port for the web server to run on as well as let it dynamically generate one. Both do not help the situation.

Any help?

Thanks.

Answer 2

The problem was I had a InstallShield Lite project which was apparently causing problems. Once I unloaded that project, I can launch the development server in debugging mode.
