Description Kirill Osenkov 2017-05-03 17:39:29 UTC
1. git clone https://github.com/Microsoft/vs-mef
2. git checkout TurnOffGitVersioningOnMac
3. Open /vs-mef/src/Microsoft.VisualStudio.Composition.sln in XS 7.0 (need a recent XS that supports opening .NET Core projects)
4. Build
5. Download and unzip https://www.nuget.org/packages/xunit.runner.console/2.2.0 to a folder such as /xunit
6. ~/vs-mef/bin/Tests/Debug/net451> mono ~/xunit/xunit.console.x86.exe ./Microsoft.VisualStudio.Composition.Tests.dll -noshadow

The results are not always exactly the same but it crashes every time, the one we see the most is an assert in sgen.
