We're using xUnitAdapter with new csproj targeting net461 framework. Everything was working fine until recent update of xUnit NuGet package to version 2.4.0. Since then no tests are being discovered.
I'm attaching MyCalculator sample project converted to new csproj format with SpecFlow.xUnitAdapter.Config.cs file added and using SpecFlowEmbeddedFeature to add feature files.
Specflow.xUnitAdapter.xUnit24.Repro.zip
If I switch the package version back to 2.3.1 all test are discovered and pass as expected.
