What's New in .NET 10 (LTS): Runtime, Libraries and SDK
A practical tour of .NET 10 LTS: JIT de-abstraction, stack allocation, post-quantum crypto, strict JSON, file-based apps, C# 14 and the .NET 11 outlook.
.NET Platform & Runtime
Understand how .NET works under the hood: the CLR, garbage collection, JIT and tiered compilation, Native AOT, dependency injection, the generic host and release cadence.
9 guides
Great .NET engineers understand the platform beneath their code. This category explains how the Common Language Runtime loads and executes your programs, how the garbage collector manages memory, how the JIT, tiered compilation and Dynamic PGO optimize hot paths, and when Native AOT is the right choice.
It also covers the building blocks every modern app relies on: dependency injection, the generic host, configuration, options, logging and background services, plus the .NET release and support policy you need for upgrade planning.
