The ASP.Net Web Configuration Manager is not anymore available in Visual Studio 2013. If you need to run it in your development server or machine, the steps below would be of great help. Before doing these steps, ensure that your sites are running on .NET Framework 4.0 or higher.
1. Open the command prompt. Note: You need to open it not as an administrator.
2. You need to be in the IIS Express folder (E.g. C:\Program Files\IIS Express>) and paste the following prompt without a quote:
“iisexpress.exe /path:C:\Windows\Microsoft.NET\Framework\v4.0.30319\ ASP.NETWebAdminFiles /vpath:/ASP.NETWebAdminFiles /port:8089 /clr:4.0 /ntlm"
Note: Use other port number if 8089 is already assigned.
3. Finally, paste this URL in your browser witout a quote:
"http://localhost:8089/asp.netwebadminfiles/default.aspx?applicationPhysicalPath= C:\Users\drmindweb\Documents\Visual%20Studio%202013\Projects \QualityModule\&applicationUrl=/"
