title: Why doesn't Exec Command work in a .csproj for netstandard2.0?
body: <p>I'm busy moving my code from .Net Framework libraries to .netstandard2.0 libraries. So far it's going pretty well, but now i'm stuck with the  in the .csproj file. </p>
  
  <p>The existing project file has this defined</p>
  
  <pre><code>  &lt;Target Name="Rebuild"&gt;
      &lt;Exec Command="echo Now Rebuilding the package" /&gt;
    &lt;/Target&gt;
  </code></pre>
  
  <p>the actual command executes an exe that generates a bunch of xml classes based on an xsd. </p>
  
  <p>I cannot get this to work in a .netstandard2.0 project? </p>
  
  <p>I've searched everywhere but i cannot find a reason for this not working...</p>
