Steps to reproduce
I used this official ASP.NET and this articles to upgrade my ASP.NET Core 1.0 app to 1.1. The app compiles fine but when I run the app using F5, I get the following error
Error:
HTTP Error 502.5 - Process Failure
Common causes of this issue:
The application process failed to start
The application process started but then stopped
The application process started but failed to listen on the configured port
Further technical details
Operating system: Windows 10
Visual Studio version: 2015-Update 3 (with latest updates)
NOTE:
My app is on development machine(windows 10) running on default built-in IIS express. No server or migration to a different sever is involved.
Windows Event Log:
Failed to start process with commandline '"C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\Web Tools\ProjectSystem\VSIISExeLauncher.exe" -p "C:\Program Files\dotnet\dotnet.exe" -a "C:\DotNet2015\src\ABCTest\bin\Debug\netcoreapp1.1\ABCTest.dll" -wd "C:\DotNet2015\src\ABCTest" -wbe Global\Build30603dd4-5933-4547-8aff-af488d42458c -lse Global\Launchf9d250ad-37e9-4e5b-8375-46f63c747deb', ErrorCode = '0x80004005'.

回答1:
You need to install the Current
release from https://www.microsoft.com/net/download/core
回答2:
Did you install the 1.1 runtime? When you update your references, it doesn't auto install it.
回答3:
I found same problem but my target frame work is netcoreapp2.0 and I solved it by using Self-contained deployment without third-party dependencies per Microsoft document following.
See here solution
