EF Core 9 support

[lauxjpn]

We will use this issue to track the progress on supporting EF Core 9, including its previews.

Prerelease 9.0.0-preview.1 (compatible with EF Core 9.0.0-preview.1.24081.2) is now available on nuget.org.

Hi @lauxjpn, do you have any plans to update to 9.0.0-preview.5?

The same for .NET 9 preview7 ?

I think we need a release for .NET 9, RC1. I get this error:

[lauxjpn]

An EF Core 9 RC compatible Pomelo release will be out in about 2-3 weeks.

Anyone else getting this both with Pomelo RC1 and RC2, .NET9 RC2:

Yeah, seems to be more members were added in the RC vs the preview in entity framework itself.

@lauxjpn Can we please get a NuGet release that's compatible with RC2 soon? I'd like to run our 9000+ test suite against it. I don't mind using the pomelo-nightly feed.
