VSTest is removing its long-standing Newtonsoft.Json dependency in .NET 11 Preview 4, switching to System.Text.Json on .NET and JSONite on .NET Framework. Here's what breaks, why it matters, and how to fix it.
SkiaSharp 4.0 Preview 1 lands with Skia milestone 147, a proper variable font API, immutable SKPath backed by SKPathBuilder, colour font palettes, and Uno Platform stepping in as co-maintainer. Here is what changed and what it means for your .NET graphics code.
A critical HMAC validation bug in Microsoft.AspNetCore.DataProtection lets attackers forge authentication cookies and decrypt protected payloads. Upgrading to 10.0.7 fixes the code, but key rotation and artifact auditing are essential to close the window fully.
The C# Dev Kit team replaced their C++ Node.js addon with C# compiled via .NET Native AOT, eliminating Python and node-gyp from their build chain. Here's how N-API, UnmanagedCallersOnly, and LibraryImport make it work.
Asp.Versioning v10.0.0 brings first-class integration with .NET 10's built-in OpenAPI library, replacing the Swashbuckle-era workarounds with a single AddOpenApi call, automatic per-version documents, and RFC 9745 deprecation headers.
At VSLive! Las Vegas, Microsoft confirmed that Visual Studio 2027 will arrive as an in-place update to 2026 — not a side-by-side install. Here is how the new annual rolling release model, decoupled build tools, and LTSC channels change daily life for .NET developers.
UnsafeAccessorAttribute lets you access private fields, methods, and constructors at the same speed as direct calls — no reflection, no Reflection.Emit, and full Native AOT compatibility. Here's how to use it, when it makes sense, and where developers trip up.
Ubuntu 26.04 LTS ships .NET 10 in the default package archive, ending years of package conflicts and multi-feed confusion. Here is what changed, how to set up your environment, and what the new container images and Native AOT tooling look like.
.NET 11 Preview 3 adds built-in pin clustering to the MAUI Map control, grouping nearby markers automatically on iOS, Mac Catalyst, and Android without requiring external packages.
Microsoft's C# Dev Kit team replaced their C++ Node.js addons with C# and Native AOT, eliminating Python dependencies and simplifying their build pipeline. Here is how N-API, UnmanagedCallersOnly, and a custom DLL import resolver make it work.
Microsoft's emergency .NET 10.0.7 out-of-band update patches a CVSS 9.1 flaw in the Data Protection managed encryptor. If you run ASP.NET Core on Linux, your HMAC validation was effectively broken since .NET 10 shipped.
.NET 11 Preview 3 reworks the Virtualize component to measure actual item heights at runtime using a running average, eliminating the broken spacing and scroll jumps that plagued lists with variable-height content since the component shipped in .NET 5.
EF Core 11 Preview 3 ships GetEntriesForState to bypass DetectChanges, ExcludeForeignKeyFromMigrations for cross-boundary relationships, migration tree divergence detection, and leaner join generation. It also bumps SqlClient to 7.0 and makes MigrationsNotFound throw by default.
.NET 11 Preview 3 adds the #:include and #:exclude directives to file-based apps, letting you split scripts across multiple files without reaching for a .csproj. Here is how they work, what they don't do, and where the edges still need sanding.
Microsoft's April 2026 servicing update patches two high-severity vulnerabilities in System.Net.Mail and System.Security.Cryptography.Xml. Here is how they work, why they matter, and what you need to do.
TickerQ replaces the reflection-heavy plumbing of Hangfire and Quartz.NET with compile-time source generators, EF Core persistence, and a built-in real-time dashboard. Here is how to set it up, define jobs, and avoid the gotchas.
The .NET 11 Preview 3 SDK ships a named-pipe coordination layer between dotnet watch and Aspire AppHosts, enabling per-resource hot reload, crash recovery with deferred relaunch, and proper Ctrl+C handling for Windows desktop apps.
Visual Studio 18.5 ships a Debugger Agent that reads your bug report, sets breakpoints, watches runtime state as you reproduce the issue, and proposes a verified fix. Here is how the workflow operates and where it fits alongside the existing Profiler and custom agents.
.NET 11 Preview 3 ships JIT improvements that eliminate bounds checks, fold switch expressions into branchless code, and speed up casts -- plus VM-level wins like 200x faster interface dispatch on iOS and faster GUID generation on Linux. Here is what changed and why it matters.
Three new features in .NET 11 Preview 3 give you fine-grained control over JSON serialisation: a built-in PascalCase naming policy, a per-member naming attribute, and type-level ignore conditions.
Since .NET 9, the System.Threading.Lock type gives you a dedicated, faster, and semantically clearer alternative to locking on a bare object. Here is how it works, why it is roughly 25% faster than Monitor, and what to watch out for when migrating.
.NET 11 Preview 3 brings multi-file file-based apps via #:include, inline environment variables with dotnet run -e, CLI-editable solution filters, and a dotnet watch that recovers from crashes and integrates with Aspire.
EF Core 11 finally brings first-class full-text search support for SQL Server, including migration-managed catalogs and indexes, and FREETEXTTABLE/CONTAINSTABLE translation with ranking scores baked into your LINQ queries.
System.IO.Pipelines is the API that powers Kestrel's legendary throughput, yet most .NET developers still reach for raw streams and byte arrays. Learn how PipeReader and PipeWriter eliminate the buffer-management nightmare and give you backpressure for free.
Orleans turns distributed systems into a problem you already know how to solve. Its virtual actor model lets you write single-server C# that the runtime scales across a cluster, handling activation, placement, and fault recovery behind the scenes.
