7.4.6

FoundationDB .NET client 7.4.6 targets .NET 11 RC1, serializes .NET 11 union types, formats dates two to five times faster, and the emulator now applies the cluster's 5 second history window.

Full release notes: https://snowbanksdk.github.io/foundationdb-dotnet-client/releases/7.4.6.html

Highlights

SnowBank:

• CrystalJson serializes .NET 11 union types (write side, work in progress).
• CrystalXml serializes a [DataMember] with a non-public setter instead of rejecting it with CXML0013.
• Types without a parameterless constructor deserialize through their constructor.
• Generator diagnostics respect #pragma warning and .editorconfig.
• TuPack unpacks into a caller-supplied Span<Range>, with CountItems to size it.
• Dates format and parse two to five times faster, and an Instant keeps its nanoseconds.
• Seven date-literal defects fixed in the parsers and DOM factories.
• String literals, decimals, and Guid values serialize faster.

FoundationDB:

• The emulator (FoundationDB.FakeDb) applies the cluster's 5 second history window.
• FoundationDB.Client.Native ships one package per branch (7.4.7 and 7.3.78), with a new osx-x64 runtime.
• Aspire: the 7.4 image tag is now 7.4.7.
• The experimental text index writes documents without reflection.

Breaking changes

• The net11.0 build targets .NET 11 RC1. Its BCL and ASP.NET Core assets depend on 11.0.0-rc.1 packages, so a consumer building that target needs the .NET 11 RC1 SDK. The net10.0, net9.0, and net8.0 builds move to released servicing (10.0.12, 9.0.20) and need no change.
• The emulator applies the 5 second history window. A test that reads at a version older than 5 seconds of store time, or commits from a transaction older than that, fails with FdbError.TransactionTooOld. To keep the old behavior: new FakeDbStore(retention: FdbSnapshotRetention.KeepEverything).
• FoundationDB.Client.Native version numbering now follows the native version (7.4.7, 7.3.78); a project pinning the exact 7.4.4.1 should move to 7.4.*.
• Dates built through the DOM change their text (whole seconds without a fraction, an unspecified midnight as a date only, default(Instant) as ""). Every spelling still parses back to the same value; only tests, hashes, and byte comparisons over the JSON text see a difference.
