After installing Preview 1 of the tooling, TypeScript errors aren't shown

[michaelaird]

After installing Preview 1, any TypeScript compilations stopped showing detailed error messages. In particular, they wouldn't show up in Task Runner Explorer when running gulp tasks.

It would show "x semantic errors" but not show the error/file/line number.

Uninstalling Preview 1 and re-installing the web developer tools fixed the issue.

it seems console.error messages are not displayed

I guess that this issue with gulp-sass errors not being shown could be another symptom of the same problem.
