c# – Publish and run ASP.NET 5 MVC WebAPI Service on IIS 8.5

In the last days I tried to publish a new created ASP.NET 5 WebAPI Webservice on an IIS 8.5.
But after publishing the Webservice didn’t started. I received the following error message:

Installation Server:

• Add at least the following server roles: Web Server (IIS) and ASP.NET 4.5

  – Get a list of all currently installed DNX versions:
  dnvm list
  – Install the DNX version 1.0.0-rc1-update1 x64 or any other version depending on the publishing settings in Visual Studio.
  dnvm install 1.0.0-rc1-update1 -arch x64
