Updated to latest version of abstractions assembly, so that it can work with the latest version of the VSTest adapter.
Dropped the .NET Standard target. Leveraging CallerArgumentExpression for automatic result naming is important for FlUnit - the LINQ expression approach for pre-.NET 6 doesn't really cut it as an alternative, and having to manually name assertions undermines part of the benefit of FlUnit. Further, the VSTest adapter simply doesn't work for full framework when your test project needs binding redirects - I'd need to do work that I'm not particularly interested in doing at this point to make this happen. I suspect that literally no-one will care - but on the off-chance that someone does, feel free to reach out. Just bear in mind that the first suggestion is likely to be that you pitch in if you want this re-added.
