  <p>Strangely, there is no tsconfig.json/tsconfig.json file. There is only a tsconfig.json file.</p>
  
  <p>My tsconfig.json file is: </p>
  
  <pre><code>{
    "compilerOptions":{
        "target" : "es5",
        "sourceMap": true,
        "rootDir": "src"        
    }
  }
  </code></pre>
  
  <p>Visual Studio has stopped transpiling my TypeScript. How can I resolve this issue?</p>
  
  <p>Excluding tsconfig.json resolve the issue... but is there another way?</p>
  
  <p>Is it because of this message?</p>

Your project may be using TypeScript language features that will result in errors when compiling with this version of the TypeScript tools.
