Is there a reference implementation of tsconfig.json being used in Visual Studio? #6504

This is probably related to #6317 but not exactly the same.

Having not used Visual Studio for a while I've just come back to it and been trying to use tsconfig.json in a standard ASP.Net MVC 5 project. For reasons that aren't clear to me the tsconfig.json doesn't appear to be being detected by Visual Studio in the way I would hope. There doesn't appear to be a reference implementation that I can refer to of how tsconfig.json should look in a Visual Studio project. Here's my assumptions / experiences:

• tsconfig.json is included with a Build Action of "Content" and a Copy to Output Directory of "Do not copy"
• tsconfig.json can sit in the root of the Visual Studio project (alongside package.json etc)
• you can't stop Visual Studio forcing these options upon your csproj:

  <PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Debug|AnyCPU'">
    <TypeScriptTarget>ES5</TypeScriptTarget>
    <TypeScriptJSXEmit>None</TypeScriptJSXEmit>
    <TypeScriptCompileOnSaveEnabled>False</TypeScriptCompileOnSaveEnabled>
    <TypeScriptNoImplicitAny>False</TypeScriptNoImplicitAny>
    <TypeScriptModuleKind>None</TypeScriptModuleKind>
    <TypeScriptRemoveComments>False</TypeScriptRemoveComments>
    <TypeScriptOutFile />
    <TypeScriptOutDir />
    <TypeScriptGeneratesDeclarations>False</TypeScriptGeneratesDeclarations>
    <TypeScriptNoEmitOnError>True</TypeScriptNoEmitOnError>
    <TypeScriptSourceMap>False</TypeScriptSourceMap>
    <TypeScriptMapRoot />
    <TypeScriptSourceRoot />
  </PropertyGroup>

It's non-negotiable; you take them out it'll put them right back in next time you edit your project properties in VS.

I've kind of given up on tsconfig.json in Visual Studio now as I think I'm somehow missing the point. It would be great if there was an example implementation to refer back to. I notice that there doesn't seem to be a File -> New Project experience for tsconfig.json which is a shame.
