There are issues with the request or def

Answer 1

Recently I had the same issue: installed VS2017, configured build agent, visualstudio and msbuild capabilities missing.

Try installing VS2015 next to VS2017. Re-configure the build agent after this (in my case, I completely removed all the old _diag, _work and settings.json data as well). This fixed the issue for me, the missing capabilities were now recognized.
