EF Core 7 InMemory - Throwing System.ArgumentException with any query involving a SmartEnum

Can you share what version(s) of EF Core and SmartEnum libraries you're on? I know you said latest but just confirming so I can reproduce with the same stuff you have. Thanks!

Yeah no worries:

Ardalis.SmartEnum 7.0.0
Ardalis.SmartEnum.EFCore 7.0.0
Microsoft.EntityFrameworkCore 7.0.5
Microsoft.EntityFrameworkCore.InMemory 7.0.5

Thanks for taking a look!

Dug into it a bit more today and the issue seems to only happen when checking for null using operators, it works fine when using '.Equals'.
i.e.:

            ClaimOutcomeEnum outcome = await dbContext.Table_Test
                    .Where(q => !q.ClaimOutcome.Equals(null))
                    .Select(t => t.ClaimOutcome)
                    .FirstOrDefaultAsync();

This works fine, however

            ClaimOutcomeEnum outcome = await dbContext.Table_Test
                    .Where(q => q.ClaimOutcome != null)
                    .Select(t => t.ClaimOutcome)
                    .FirstOrDefaultAsync();

bombs out with 'System.ArgumentException'. (sorry, I know this is different to my original example!)
