CI build fails after merge to master

[mbhoek]

After merging PR #17 into master, the automated CI build failed.

error CS0246: The type or namespace name 'SolidToken_SpecFlow_DependencyInjection_Tests_XUnitAssemblyFixture' could not be found (are you missing a using directive or an assembly reference?) [D:\a\1\s\SpecFlow.DependencyInjection.Tests\SpecFlow.DependencyInjection.Tests.csproj]

However, on the same master branch a manual build succeeds.
The pull request build also succeeded.

Is this a repeatable bug? What causes it? Is it solved by moving to GitHub Actions (#11)?

Probably related to SpecFlowOSS/SpecFlow#1825 (but does that explain it happening in the CI environment as well?). If it is a problem in SpecFlow, then moving to GitHub Actions won't solve it.

Downgrading to SpecFlow 3.0.225 results in a different error (note it still has something to do with the fixture):

    System.AggregateException : One or more errors occurred. (Value cannot be null. (Parameter 'key')) (The following constructor parameters did not have matching fixture data: FixtureData fixtureData)
    ---- System.ArgumentNullException : Value cannot be null. (Parameter 'key')
    ---- The following constructor parameters did not have matching fixture data: FixtureData fixtureData
