Record types sythetic PrintMembers delegates to synthetic overridable PrintMember

[drdamour]

Been loving record types really great for client/server interactions and command/event. The ToString is awesome for quick log/dumping. But i find overriding PrtingMembers to consistently be a pain because i have to take over everything pretty much. Often i just want to make sure a single IEnumerable property dumps the way i want.

If there was one more layer of indirection in the synthetic generation it would make this way easier. If PrintMembers delegated to a PrintMember(StringBuilder, string memberName) or maybe even a PrintMember(StringBuilder, string memberName, object? value) i could easily switch expression the construction for my special members. Could even see there being a static method somewhere in runtime to do the default output.

i think this would be compatible because anyone who has overridden ToString or PrintMembers wouldnt be affected. If they already added a PrintMember method with same signature that could be an issue as they would already replace the synthetic print.

Im guessing i can leverage source generators to create my own PrintMembers at compile time as a different way of solving my goal but this indirection seems simpler.

Yup. And we explicitly decided that was the way we felt was great for them ecosystem here. Sorry!
