@dotnet/dotnet-cli It's not clear to me why the Ubuntu build failed:

@davkean you can see the failing test result from here

@davkean this again https://github.com/dotnet/cli/issues/4660

You can re queue it by "@dotnet-bot test Ubuntu x64 Release Build"

looks good to me @johnbeisner what do you think?

[nguerrera]

Looks good. Are those RelWithDebInfo, MinSizeRel, etc. configurations used. It's wiring them to debug project configurations which looks wrong. I think we should delete the solution configurations.

[davkean]

Are they solution configurations only or coming from projects?

[nguerrera]

Search turns them up only in the sln. I think they're dead code. Official builds don't use the sln.
