1. uses a ContextFixture (which requires Disposal)
2. keeps all Context/ContextFixture+Do+Assert/Observation in a single Test Method at all costs -- lambdas get very yucky the minute you factor calls to any of these into test methods
3. The TheoryDataProvider junk at the end is also applicable to xUnit [Theory] stuff (and you use the same [ClassData] and friends as one uses for other xunit.net stuff and just removes some cruft from writing up test cases)
4. uses sut/result/exception standard names
5. This is a sample and has stuff that doesnt scale up that I wouldnt do. e.g. dont use Conditional Logic in tests with care - something as simple as a should succeed / should fail set of cases should generally be two separate Thesis methods

Go look in bitbucket - there's a good set of tests that serve as a better set of samples.

This snippet will self destruct when someone tells me that the acceptance tests and samples in Johannes' fork are clearer and more complete
