Obfuscators rename members and types, and Json.NET reads those CLR names to write JSON keys and $type discriminators, so payloads change without any error. The article explains how to pin wire names with [JsonProperty], [EnumMember] and a stable ISerializationBinder, and how to test the protected build.
The author of the C# interpreter HydraScript explains why numeric instruction indexes broke code generation and how switching to stable IAddress objects fixed it. Addresses now stay with their instructions when code is inserted, removed or replaced, so jumps keep pointing to the right place. It is a concrete case for developers building compilers or interpreters with the Visitor pattern.
.NET MAUI 10.0.120 is out with 213 commits focused on quality. The release fixes BlazorWebView memory leaks and disconnect issues, several CollectionView regressions on iOS and Android, plus Editor, Entry and TimePicker behavior. If you ship MAUI apps with CollectionView or Blazor Hybrid, these fixes are worth checking against your app.
This guide explains how to scale ASP.NET Core SignalR across several servers using either a Redis backplane or Azure SignalR Service. It covers why messages fail to reach clients on other servers, how each option distributes them, and when sticky sessions are still needed. It is a practical starting point for teams moving real-time apps into production.
Microsoft has released a public preview of dotnetup, a cross-platform tool that installs and updates .NET SDKs and runtimes in the user's own directory without admin rights. It follows channels such as latest, lts and preview, reads global.json, and cleans up unused installs. Commands may still change before general availability.
An overview of the C# 15 features: union types, closed class hierarchies, named break and continue, extension indexers, with-arguments in collection expressions and the revised unsafe model. It shows how each one changes everyday code and where the caveats are.
Cookie authentication in ASP.NET Core serializes the whole AuthenticationTicket into the cookie, so large claim sets can push it past WAF limits. Implementing ITicketStore keeps the ticket on the server and leaves only a session key in the cookie. The article compares an in-memory store with a distributed cache version and discusses the scaling and revocation trade-offs.
ServiceStack v10.4 lets typed OrmLite queries reach into complex properties such as x.Address.City or x.Lines.Any(...). The expressions are translated to the native JSON functions of SQLite, PostgreSQL, SQL Server and MySQL, so one query works across all four. This removes the need for Sql.Json() wrappers on complex properties.
Mauro Servienti released Zusammen, an alpha Node.js library that brings the NServiceBus transactional session idea to Node.js. Business data and outgoing messages are committed together in one MongoDB transaction, with a control message and tombstone guarding dispatch to RabbitMQ. It is also a useful case study in AI-assisted development, and a concrete look at the outbox pattern for .NET developers.
