Answer 1

unable to connect to configured web server

For me it worked out when i uninstalled skype and visual studio ,then deleted IIS folder from documents.....And again installed visual studio first then installed skype....Try it out...

Answer 2

This happened to me.

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

I was able to fix it by deleting the auto-generated IISExpress folder, which is usually located at %userprofile%/Documents, e.g. C:\Users\[you]\Documents\IISExpress.

When I ran the project again, it created a new folder with a valid IIS config file and I could run the debugger.

Answer 3

This happened to me in a Web Site Project. The solution was to close the solution, delete the project's .vs folder and rebuild.

Answer 5

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

I tried many of the other suggestions to no avail, but this worked a treat.

Answer 6

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 no.

It will work !! Happy Coding

Answer 7

The reason might be Skype using some ports which are configured in your project. Quit Skype and try again.

Also I noticed that if I delete the %userprofile%/Documents/IISExpress folder, then IISExpress will show a popup notification specifying exactly which program is blocking it from starting.
