dotInsights | September 2026 - The JetBrains Blog
Blog post from JetBrains
JetBrains’ September 2026 dotInsights newsletter, curated by Rachel Appel, highlights recent .NET and software development resources alongside the note that the open-source C# Roslyn compiler is itself written in C# and provides code-analysis and generation APIs. Its linked coverage spans .NET 11 performance and security features, Azure Service Bus filters, ASP.NET Core authentication and CSRF protection, code obfuscation, digital signatures, URI and IP-address handling, Blazor CSV and search capabilities, .NET MAUI UI development, Orleans and DocumentDB, Kubernetes memory optimization, architecture patterns, and local AI models. The issue also examines AI-assisted development, including coding-agent workflows, risks, user-experience patterns, and the role of engineers, while JetBrains announcements promote GameDev Day, .NET Day Online, the Rider 2026.3 Early Access Program, Rider and ReSharper updates, and AI-agent access to Rider’s refactoring engine.
