Why ASP.NET Web Configuration Tool wouldn’t open from VS Web Developer Express 2012?

I had to play with ASP.NET Web Configuration Tool from VS Web Developer Express 2012 for an issue.

So I went to Website menu and selected “ASPNET Configuration” but it wouldn’t open. So I opened my classic Visual Studio 2005 Pro and it worked fine.

After looking over again and again I realized the configuration tool from VS 2005 opened in IE. When I looked at my VWD Express, I had Firefox selected as default Debug browser.

When I changed it to Internet Explorer, the Configuration tool opened just fine.

So I went to VS 2005 Pro and set Firefox as Default Browser and it did open the tool in Firefox.

So I am not sure if this is a know issue with VWD. I couldn’t find any reference to this issue on the web.

Hope this helps.
