title: VS2019 - MSBuild SdkResolver fails to run when using C#
body: <p>I'm trying to get started with c# (I've been using VS for C++ without issue) and whenever I try to open a C# Project I get this error:</p>
  <pre><code>The project file cannot be opened. The SDK resolver &quot;Microsoft.DotNet.MSBuildSdkResolver&quot; failed to run. Illegal characters in path.
  </code></pre>
  <p>The .csprj only has 7 lines!</p>
  <pre><code>    &lt;Project Sdk=&quot;Microsoft.NET.Sdk&quot;&gt;
  
    &lt;PropertyGroup&gt;
      &lt;TargetFramework&gt;netstandard2.0&lt;/TargetFramework&gt;
    &lt;/PropertyGroup&gt;
  
  &lt;/Project&gt;
  </code></pre>
  <p>I tried swapping the <code>&quot;</code> for <code>'</code> but got the same error.</p>
  <p>Running VS2019 with <code>/ResetSkipPkgs</code> prevents this issue from happening and the project loads fine. However I can't find the source of the issue.</p>
  <p>Does anyone else know what could be causing this? I'd like to be able to work on C# projects without running VS via commandline every time!</p>
