Answer 1

If could be of help I have a little update. As explained in the previous issues, after I've seen the problems with 1.8 I tried to uninstall it and reinstall 1.7 to continue to work to my projects, but even the installation was ok I had different problems compiling these asp.net 5 apps. I tried repairing vs, uninstalling and reinstalling 1.7 and 1.8 in any order without any changes. In the end I checked the directory C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\TypeScript and I found that at the end of the uninstall of every version of typescript I have this

search for this folder and delete At this point I tried to remove this directory completely and retried to uninstall typescript 1.7.6. and now it works fine. I tried doing this cleaning up and installing 1.8 beta, but I continue to have the same problem, but at least now I can work on asp.net 5 projects. I think that the problem rolling back to previous version was unable to overwrite at least the TypeScript.Tasks.dll generating an inconsistent behavior. Could be possibile that to make work nightly builds of 1.8

and the error TS5042 solve. I hope this help you.
