If you create a standard JavaScript/Node.js project, and then later Add New Item->TypeScript file, it should make the necessary changes to the project to support TypeScript. Same if a TypeScript file gets added some other way (add existing file, drag & drop from explorer, right-click include in project).
If we don't do that automatically, we could have a command that does it. Worse case, we document how to do it. Example of what they need to change:
```
<TypeScriptSourceMap>true</TypeScriptSourceMap>
<TypeScriptModuleKind>CommonJS</TypeScriptModuleKind>
<EnableTypeScript>true</EnableTypeScript>
```
