Visual Studio does not recognize Unreal Files

Hey there, I just set up Unreal and Visual Studio on my working computer but I can’t get it compiling. When I open my solution file it looks as if Visual Studio could not find the UE files:

What I have done so far:

  • deleted .sln, .vs, Binaries, Saved and Intermediate and recreated the Visual Studio files
  • reinstalled Epic Games Launcher and Unreal Engine
  • double checked if everything I need in Visual Studio is installed (Game development with C++, Windows 8.1 SDK, Unreal Engine Installer)
  • manually installed Windows 8.1 SDK
  • used the UnrealVersionSelector.exe as described in the answer by ZimaXXX [here][2] because at the very beginning my .uproject file was not detected as an Unreal project

Nothing of the above helped me to solve the errors shown in the picture. Is there anything else I can try to do?
