We've seen this in the past, but it was fixed several months ago.

@MSLukeWest are you aware of any changes that could have caused this?

@mthalman does your local builds work fine? Release and debug?

[mthalman]

Release config fails locally too.

@NikolaMilosavljevic I'm not aware of any changes that could have caused this, the build worked fine the last time I edited NETCoreCheck a couple months ago. If you'll recall, last time this was fixed by updating the .NET Toolset, see https://github.com/dotnet/deployment-tools/pull/87/files. Has the toolset been updated since then?

@mthalman If you're blocked by this just go ahead and change this property to true:

https://github.com/dotnet/deployment-tools/blob/3c246e582164af60a222930a2073ba2e1fa6b807/eng/Subsets.props#L73

That will disable building NETCoreCheck for now, which is OK because there's currently no planned updates.
