问题
I'm currently having two projects with typescript 1.1 that are opened in visual studio 2013 with typescript 1.8 installed. VS asks to upgrade which I did but now I get the following error: Unknown compiler option 'listemittedfiles'. Anyone has had the same?
回答1:
It seems inside the project we had this line hardcoded
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\TypeScript\Microsoft.TypeScript.targets" />
That way even though it was upgraded to 1.8 it still tried to use w/e was installed in that folder. (This is a very old project that needs maintenance...)
Next to that I've removed the hardcoded path in the Path system environment variables so that tsc.exe now points to the NPM version.

If the above answer doesn't work for you, I suggest to take a look to this other answer which addressed that same issue on Visual Studio 2015 Update 3 and above:
(to summarize it, installing TypeScript 2.0 from this official link might fix the messed-up MSBuild cfg and solve the issue).
