title: Do you have to have .net core installed on a system before using self contained apps?
body: <p>I'm using Visual Studio 2019 to publish a self contained .net core 2.1 app. Many files are emitted during the publishing (application files as well as core libraries). </p>
  
  <p>But there is no dotnet.exe included in the published files. Without a dotnet.exe I can't launch the published app!</p>
  
  <p>So I'm confused. Must you have a system wide .net core installed to use self-contained apps, and if so, then you're app certainly isn't self contained.</p>
