I have installed Visual Studio Community Edition on Windows 10 with IIS Express 10.0
When I created a new web project using provided template of Asp.NET Core 1.1, project did not launch in any browser , In event viewer I get following error.
Application 'MACHINE/WEBROOT/APPHOST/TESTAPPLICATION' with physical root 'D:\Projects\Aspnet Core1.0\TestApplication\TestApplication\' failed to start process with commandline '"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\Extensions\Microsoft\Web Tools\ProjectSystem\VSIISExeLauncher.exe" -debug -p "C:\Program Files\dotnet\bin\dotnet.exe" -a "exec \"D:\Projects\Aspnet Core1.0\TestApplication\TestApplication\bin\Release\netcoreapp1.1\TestApplication.dll\"" -pidFile "C:\Users\DELL\AppData\Local\Temp\tmp8A1D.tmp" -wd "D:\Projects\Aspnet Core1.0\TestApplication\TestApplication"', ErrorCode = '0x80004005 : 0.
Note in my other machine with Windows 8.1 there is no issue with same configurations and projects run successfully there in Visual Studio 2017.
The main issue was My machine already had Visual Studio 2015 Community Edition with updates side by side of Visual Studio 2017.
I removed it and then I tried to remove all individual program beginning with word Core (SDK and runtime etc).
Then I remove .NET Core Command-Line Interface (CLI) Tools after that Visual Studio 2017 worked like a charm.
