where is Web Site Administration on visual studio 2015
I experienced the same issue. You can get to it via IIS or as I did, I copy it to a development folder for future use. Here are two options...
1. Launch the Web Site Admin Tool using a command window:
Open a Command Window running it as a Admin
Change the folder to IIS Express:
cd C:\Program Files\IIS Express\- Run the following command to start up IIS Express:
iisexpress.exe /path:C:\Windows\Microsoft.NET\Framework\v4.0.30319\ASP.NETWebAdminFiles /vpath:"/ASP.NETWebAdminFiles" /port:8082 /clr:4.0 /ntlm
- Access the Admin Site via the following URL: http://localhost:8082/asp.netwebadminfiles/default.aspx?applicationPhysicalPath=C:[YOUR SITE PATH HERE]\&applicationUrl=/
2. Launch the Web Site Admin Tool using IIS: You can try running the site from the Windows folder but after a couple of issues I just moved it to another folder. The steps below cover that process.
Copy the Admin Site from the following folder: C:\Windows\Microsoft.NET\Framework\v4.0.30319\ASP.NETWebAdminFiles
Change the web.config to allow any user to access the site
Setup the site in IIS. Set the Authentication as shown below. Use the following URL to manage your ASP.NET site.
http://localhost/ASPNetAdmin/default.aspx?applicationPhysicalPath=C:[YOUR SITE PATH HERE]\&applicationUrl=/
