NullReferenceException in remoting when running xunit #8720
Description
Appologies if this is xUnit, or msbuild or .NET CLI or else but since it reproduces only with Mono on Linux and macOS, I'm raising it here.
Steps to Reproduce
- Checkout https://github.com/bruno-garcia/mono-xunit-issue
- dotnet test
Current Behavior
[xUnit.net 00:00:01.8591040] mono-xunit-issue: Catastrophic failure: System.NullReferenceException: Object reference not set to an instance of an object
Expected Behavior
Test pass (it passes on .NET Framework 4.7.2 and .NET Core 2.1rc (when I target netcoreapp2.0)
