title: How do you suppress this warning in VS: "The type of schema applied to the document is not supported"
body: <p>This morning I created an MSTest project in C#, and for one of the JSON resources, Visual Studio is showing this warning:</p>
  <pre><code>The type of schema applied to the document is not supported
  </code></pre>
  <p>However there's no option available in the tooltip that allows you to suppress it.  So then I started looking for a specific code or something to look for in the project settings; however <a href="https://docs.microsoft.com/en-us/cpp/error-messages/compiler-warnings/compiler-warnings-c4000-c5999?view=msvc-160" rel="noreferrer">Microsoft's apparently full list of compiler warnings</a> doesn't list this one, for whatever reason.  Since this is a test project, I could probably just suppress all warnings across the board and be fine, but that's still not ideal.</p>
  <p>Is there a way to suppress this one surgically, ideally in a way that applies throughout the project?</p>
