Today morning when I tied to run my project I get "The start URL specified is not valid" error". I just install the newest Azure SDK.

In IIS Manager I see this, I can't start, restert website.

Why I can't run my project, any ideas? I have no logs in Event Logs. I use VS2015 Ultimate.

It could be a short answer but I too had this problem after deleting IISExpress folder inside this path

"C:\Users\{username}\Documents"

after reading this article.

but I solved this problem by doing these steps.

1)Run Visual studio as Administrator

2)Uncheck Override application root Url

enter image description here

then run just hit launch project.

I was playing w/ things and I guess I accidentally cleared this setting. Different from other answers here, but the message does say 'Start url...' I set it back to 'localhost:4300' and was back plodding along.

Just restart your visual studio will do. Everything will be fine after that.

All I had to do was restart Visual Studio 2017 CE.
