Unable to connect to web server 'IIS Express'.

by Damir Dobric

As a Visual Studio developer, you might probably very often get following error:

Unable to connect to web server 'IIS Express'.

There are many resons why this can happen. It happen mostly when changing something in the configuration. Anyhow, I found following workaround.

Close VS and delete the .vs folder, that is in the root of your solution.

Hope this helps.
