ASP.NET Core IIS error: HTTP error 502.5–Process failure

After enabling .NET Core on my web server I was finally ready to run my ASP.NET Core app. Or at least that was what I thought… When I opened my browser IIS welcomed me with the following error message:

clip_image002

After enabling stdout logging inside the web.config of my ASP.NET Core app I saw following error:

The specified framework 'Microsoft.NETCore.App', version '1.1.2' was not found.

  - Check application dependencies and target a framework version installed at:

      C:\Program Files\dotnet\shared\Microsoft.NETCore.App

  - The following versions are installed:

      1.0.4

      1.1.1

  - Alternatively, install the framework version '1.1.2'.

That is great and meaningful error message. I downloaded the latest runtime version 1.1.2, installed it, and was good to go!
