title: Visual Studio 2019 does not recognize tsconfig.json
body: <p>I just installed Visual Studio 2019 and tried it with my current solution. It seems like it ignores the <code>tsconfig.json</code> file, while it worked in VS 2017.
  In Visual Studio 2017 in project properties: TypeScript Build, it shows:</p>
  <blockquote>
  <p>One or more tsconfig.json or jsconfig.json files detected. Project properties are disabled.</p>
  </blockquote>
  <p><a href="https://i.stack.imgur.com/Yh7Fp.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Yh7Fp.png" alt="enter image description here" /></a></p>
  <p>This works good and compiles the files according to my <code>tsconfig.json</code> file.</p>
  <p>Now the newly installed Visual Studio 2019 behaves differently. It does not show that sentence and I have to configure all the settings in the project properties. It seems like it does not recognize my <code>tsconfig.json</code> file at all.</p>
  <p>How do I get VS 2019 to use the <code>tsconfig.json</code> instead of the project properties?</p>
