@livarcocc that's what i was speaking about with https://github.com/dotnet/cli/issues/6813#issuecomment-307433277

is ok to target release/2.0.0 branch?

[enricosada]

@dotnet-bot Test Windows_NT x86 Debug Build please.

[enricosada]

@livarcocc i'd like to add just one test (the happy path, no special options) for each command, is ok?

[nguerrera]

We should add basic F# coverage in dotnet/sdk repo as well. I just spotted an incoming break: dotnet/sdk#1329 (comment)

[nguerrera]

@enricosada Can you do the other checkboxes as a separate PR? I'd like us to gain better F# coverage ASAP rather than wait for the full set to be written.

[enricosada]

@nguerrera Sure, @livarcocc this PR is finished, can be merged if ok.

I'll send another next week too, with others.

@nguerrera i'll add more to sdk too, i'ld like to move also some of dotnet/netcorecli-fsc test suite too. Added dotnet/sdk#1334 to track it

@dotnet-bot Test Debian8.2 x64 Debug Build please.
@dotnet-bot Test Windows_NT x86 Debug Build please.

@MattGertz This is a test only change.
