title: Jetbrains Rider: [MSB4057] The target "build" does not exist in the project
body: <p>When I create solution in Jetbrains Rider EAP 21 I get "<em>(with missing packages)</em>" error in Solution Explorer window.</p>
  
  <p>Then, I try to build project and get <strong>[MSB4057]</strong> error.</p>

  <p>Despite this, I can run the project through Terminal:</p>
  
  <pre><code>dotnet restore
  dotnet build
  </code></pre>
  
  <p>... and get following information:</p>
  
  <pre><code>Hosting environment: Production
  Content root path: *path*
  Now listening on: http://localhost:5000
  Application started. Press Ctrl+C to shut down.
  </code></pre>
  
  <p>dotnet --info command result:</p>
