Add AspNetCoreApp to referencing Framework

Question

I have a .NetCore Project, and want to use Kestrel webserver. To do so, I need to add the aspNetCore framework. How can I do this, ans in which file? Thanks, Thomas.

I looked at the *.csproj file, but there is nor target framework in it.

Answer 1

add to <projectname>.csproj
....
  <ItemGroup>
      <!-- Add ASP CORE -->
      <FrameworkReference Include="Microsoft.AspNetCore.App" />
  </ItemGroup>

That's it.
