EF Core 11 queries implement IAsyncEnumerable<T> directly. Here is how to stream rows with await foreach, when to prefer it over ToListAsync, and the gotchas around connections, tracking, and cancellation.

A practical guide to mixing C# records and EF Core 11. Where records fit, where they break change tracking, and how to model value objects, entities, and projections without fighting the framework.

.NET 11 Preview 3 lets Kestrel serve HTTP/3 requests before the peer's control stream and SETTINGS frame arrive, shaving handshake latency off the first request on every new QUIC connection.

EF Core 11 auto-translates LINQ Contains over JSON collections to the new SQL Server 2025 JSON_CONTAINS function, and adds EF.Functions.JsonContains for path-scoped and mode-specific queries that can hit a JSON index.

Seven ways to return more than one value from a C# 14 method: named tuples, out parameters, records, structs, deconstruction, and the extension-member trick for types you don't own. Real benchmarks and a decision matrix at the end.

.NET 11 Preview 3 teaches RyuJIT to eliminate redundant bounds checks on consecutive index-from-end access and on i + constant < length patterns, cutting branch pressure in tight loops.

.NET 11 Preview 3 adds RegexOptions.AnyNewLine so ^, $, \Z, and . recognize every Unicode newline sequence, including \r\n, NEL, LS, and PS, with \r\n treated as one atomic break.

Aspire 13.2 ships an --isolated flag that gives each aspire run its own random ports and secrets store. It unblocks multi-checkout work, agent worktrees, and integration tests that need a live AppHost.

dotnet run -e in .NET 11 Preview 3 passes environment variables straight from the CLI and surfaces them as MSBuild RuntimeEnvironmentVariable items.

.NET 11 Preview 3 teaches dotnet sln to create, add, remove, and list projects in .slnf solution filters, so large mono-repos can load a subset without opening Visual Studio.
