title: How to make Visual Studio Code show really all TypeScript type errors?
body: <p>In my TypeScript/React project, "react-scripts start" shows type errors that are not shown inline in my Visual Studio Code IDE.
  Most types errors are actually shown inline, but not all.
  What could be the reason for that? How can I make Visual Studio Code show all errors directly?</p>
  
  <p>VS Code setting "typescript.validate.enable" is set to true</p>
  
  <p>My tsconfig.json:</p>
  
  <pre><code>{
    ...
    "compilerOptions": {
      ....
      "noImplicitAny": true,
      "strictBindCallApply": true,
      "strictFunctionTypes": true,
      "strictPropertyInitialization": true,
      "strictNullChecks": true,
      ...
    }
    ...
  }
  </code></pre>
