We’re pleased to announce that all new Managed Cloud Servers configured for .NET now come with .NET 10 installed by default.
This update gives developers immediate access to Microsoft’s latest framework features, including enhanced performance, improved cloud-native tooling and new C# language capabilities.
Whether you’re running ASP.NET Core apps, building microservices or deploying APIs, .NET 10 offers a modern, efficient foundation to build and scale on.
A few important notes:
- Existing servers won’t be changed. If you’re already running workloads on an older .NET version, nothing will be modified automatically.
- The .NET CLI will default to version 10.0, as provided by our upstream vendor.
What’s New in .NET 10?
.NET 10 introduces a range of improvements aimed at increasing developer productivity and runtime efficiency. Here are some key highlights:
Enhanced Native AOT (Ahead-of-Time) support
Compile apps into self-contained executables with faster startup times and reduced memory usage. Ideal for performance-critical workloads and container-based deployments.
Key runtime improvements include:
- More aggressive JIT inlining and devirtualization for tighter machine code and reduced call overhead.
- Stack allocation of small fixed-size arrays to reduce GC pressure and improve throughput.
- AVX10.2 vector instruction support for high‑performance numeric, ML, and compute-heavy workloads.
- Improved struct argument codegen and enhanced loop inversion for more efficient hot-path execution.
- Native AOT enhancements including better trimming, improved reflection analysis, and safer AOT‑friendly APIs.
ASP.NET Core performance improvements
ASP.NET Core 10 continues to push performance boundaries with improvements across the stack:
- Reduced request latency and optimised middleware pipelines for faster API and web app execution.
- Automatic memory pool eviction to reduce long‑running memory pressure in high‑traffic apps.
- Improved HTTP/3 support and networking reliability.
- Blazor updates including WebAssembly preloading, static asset improvements, and a new reconnection UI component.
- OpenAPI 3.1 enhancements and better minimal API integration.
- Passkey authentication support in Identity for modern passwordless flows.
C# 14 language updates
.NET 10 includes support for C# 14, which introduces new syntax refinements and productivity features—such as primary constructors in structs and lambda expression enhancements—that make code cleaner and easier to maintain.
- Extension members — static and instance extension properties, methods, and even operators.
- Field‑backed properties using the new field keyword for cleaner property definitions.
- Implicit Span<T> and ReadOnlySpan<T> conversions for zero‑allocation high‑performance code.
- Lambda parameter modifiers (ref, in, out) without explicit type declarations.
- nameof support for unbound generic types such as nameof(List<>).
- Partial instance constructors and partial events for more flexible code generation patterns.
- User‑defined compound operators (+=, -=, ++, –) for custom types.
Improved Cloud‑Native and DevOps Tooling
The .NET 10 SDK introduces several enhancements that streamline modern deployment workflows:
- Native container image creation for console apps directly from the SDK, with configurable image formats.
- Refined trimming and AOT‑safe APIs for smaller, safer cloud deployments.
- Enhanced diagnostics including improved event tracing and better process group support on Windows.
- CLI improvements such as native tab‑completion scripts, unified command ordering, and –cli-schema for introspection.
- Microsoft.Testing.Platform integration for more flexible and extensible test execution.
