Answer 1

It happened to me.

For me, the reason was a bad IIS configuration file.

I managed to fix it by deleting the automatically generated IISExpress folder, which is usually located in %userprofile%/Documents , for example. C:\Users\[you]\Documents\IISExpress .

When I started the project again, it created a new folder with a valid IIS configuration file, and I could start the debugger.

Answer 2

This happened to me in a website design. The solution was to close the solution, delete the project .vs folder and rebuild.

Answer 3

I had to move the solution folder to a new location. i.e.: from C: \ Documents and Settings \ David \ Desktop \ MySolution to C: \ SourceCode \ MySolution

I tried many other suggestions to no avail, but it worked.

Answer 4

you can change the default development server port no in Project (right click) → Properties-> web-> use visual studio web server-> use specific port-> and enter 1000 or any port number.

It will work !! Happy coding

Answer 5

The reason may be Skype using some ports that are configured in your project. Log out of Skype and try again.

I also noticed that if I delete the folder% userprofile% / Documents / IISExpress, then IISExpress will display a pop-up notification that will indicate which program is blocking it from starting.

Answer 6

when debugging a website, the error was pooping unable to connect configured development web server

I successfully resolved this error.

1) first remove iis 8.0 from our system 2) download iis 10.0 from https://www.microsoft.com/en-us/download/details.aspx?id=48264 3) now open a new project and check it.

4) if it still doesn’t work, check the iis manager setting on this open website by default and open authentication and enable basic, form and Windows authentication.

5) right-click on the default website and select the permission to edit to add the full control to the iis user, if it is missing, add it.

and check your project again. hope this helps you.

unable to connect to configured web server

For me, this happened when I deleted Skype and Visual Studio, then deleted the IIS folder from the documents ..... And again installed Visual Studio first, and then installed Skype .... Try it ...

Answer 8

I don’t like this answer myself because it doesn’t explain anything, but ... I found that I had to perform a complete reboot of TWICE in order to start VS again. This is probably due to windows doing dodgy updates.
