How to solve "Unable to connect to the configured development web server on" in vs2015? p.s I've checked the answers of similar questions and it didn't help.
This image is from visual studio 2015 where every time i try to view the website in browser this window pops up
I've finally solved the problem, it seems that I was missing the right of using the server (or something like that) Any way you can find the solution in this link How to solve “Microsoft Visual Studio (VS)” error “Unable to connect to the configured development Web server”
It seems that once higher version of VS installed at the system and after that working on vs lower version ,Just Delete the IIS express folder created in .../documants it will run
Running Visual Studio 2015 as Administrator working fine for me
