Keep getting "tsc.exe" exited with code 1 : <p>As soon as I add a tsconfig.json file to my Visual Studio 2015 web solution I get the above error. </p>

<p>Also this stops the compiler from re-generating js files even when I set "compileOnSave": true.</p>

<p>When I double click the error it takes me into the Microsoft.Typescript.Targets file which contains a lot of issues such as Unknown Item Group "TypeScriptCompile". In the error list these appear as warnings but they are there whether I have a tsconfig.json file or not.</p>

<p>Is there any way of solving it or getting more information on what the problem is?</p>
