I\'m running Visual Studio 2017, version 15.0.0+26228.9
When I\'m trying to create a new project via File > New > Project... in Visual Studio 2017, I\'
1/ open control panel -> program and future - > IIS Express -> select Repair
2/ Refresh some time -> open Visual Studio
This 's about IIS Express in your computer . you only need to repair it in control panel is ok .
I tried and success.
