title: In ASP.Net Core, no suitable runtime works with package reference Microsoft.AspNetCore.App version 2.1.0-rc1-final
body: <p>Summary
  I need to reference the new everything metapackage Microsoft.AspNetCore.App version 2.1.0-rc1-final to compile, but no suitable runtime is found.</p>
  
  <p>I tried installing .net core runtime 2.1.0-rc1 but this installed the <strong>.net core</strong> runtime Microsoft.<strong>NetCore</strong>.App and didn't install the <strong>aspnet</strong> core runtime Microsoft.<strong>AspNetCore</strong>.App. Where can I find it or what setting do I need? 
  Setting the runtime framework to the 2.1.0-preview didn't work:
  2.1.0-preview2-final</p>
  
  <h2>Technical details</h2>
  
  <p>I've tried to get rc1 to run on more than one project and I don't understand why a runtime doesn't exist from the sdk installation. <code>dotnet --info:</code></p>

  To install additional .NET Core runtimes or SDKs:
    https://aka.ms/dotnet-download
  </code></pre>
  
  <p>In my Csproj:</p>
  
  <pre><code>  &lt;ItemGroup&gt;
      &lt;PackageReference Include="Microsoft.AspNetCore.All" Version="2.1.0-rc1-final" /&gt;
    &lt;/ItemGroup&gt;
  </code></pre>
  
  <p>But when I run, the runtime won't accept the any of the runtimes I have installed. Is a compatible runtime not included in the RC candidate sdk and if not can I force it to run on another runtime. If not, how are other people running release candidates?</p>
  
  <pre><code>C:\Users\stick&gt;dotnet "C:\Users\stick\source\repos\Docs\aspnetcore\performance\caching\memory\sample\WebCache\bin\Debug\netcoreapp2.1\WebCache.dll"
  It was not possible to find any compatible framework version
  The specified framework 'Microsoft.AspNetCore.All', version '2.1.0-rc1-final' was not found.
    - Check application dependencies and target a framework version installed at:
        C:\Program Files\dotnet\
    - Installing .NET Core prerequisites might help resolve this problem:

    - The .NET Core framework and SDK can be installed from:
        https://aka.ms/dotnet-download
    - The following versions are installed:
        2.1.0-preview2-final at [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
