title: How to prevent Visual Studio's tsconfig detection from detecting tsconfigs in other projects?
body: <p><strong>TypeScript Version:</strong> </p>
  
  <p>1.8.30.0</p>
  
  <p><strong>Issue</strong></p>
  
  <p>We have a solution with a number of web projects. We recently made a new project which used a tsconfig.json file. </p>
  
  <p>This affected other projects to believe they had a tsconfig.json file, overriding our project typescript settings for those projects.</p>
  
  <p>"One or more tsconfig.json files detected. Project properties are disabled."</p>
  
  <p>I've checked and the project file itself does not contain any reference to any tsconfig.json files nor does the project folder contain a tsconfig file.</p>
  
  <p><strong>Reproduce</strong></p>
  
  <ol>
  <li>Create two new Web Api projects in same solution.</li>
  <li>Add a typescript file to each project and accept that they are converted into a typescript project.</li>
  <li>Add a tsconfig.json to the second project.</li>
  <li>Open properties for the first project and go to the TypeScript Build Tab. Observe "One or more tsconfig.json files detected. Project properties are disabled."</li>
  </ol>
  
  <p>How do I prevent a Visual Studio 2015 project from finding / detecting tsconfig.json files that are in another project folder?</p>
