We're also working on improving the Visual Studio experience for configuring and working on ASP.NET Core projects targeting native AOT.Book Description Paperback. 'In future previews, we're working to enable more features of ASP.NET Core and supporting technologies with native AOT, including JWT authentication, options validation, ADO.NET data access for SQLite and PostgreSQL, and OpenTelemetry. Be sure to read the current known issues regarding ASP.NET Core and native AOT compatibility. NET 8 Preview 3, and share any feedback you have by leaving a comment here, or logging an issue on GitHub. 'While it's still early, we'd love for you try out native AOT support for ASP.NET Core in. 'Native AOT deployment is not suitable for every application, but in the scenarios where the benefits that native AOT offers are compelling, it can have a huge impact,' Microsoft said in a blog post last week about ASP.NET Core updates in.

Apps include required runtime libraries (just like self-contained apps, increasing their size as compared to framework-dependent apps).Implies compilation into a single file, which has known incompatibilities.Requires trimming, which has limitations.No built-in COM (only applies to Windows).No runtime code generation via JIT (for example, ).No dynamic loading (for example, Assembly.LoadFile).Microsoft listed some key fundamental compatibility requirements for native AOT applications: New 'Enable native AOT publish' Option (source: Microsoft). Reduced memory consumption can lead to greater deployment density and improved scalability. Reduced memory demand: Native AOT apps can have reduced memory demands depending on the work being performed by the app.Improved deployment with container orchestrators that manage transitions from one version of the app to another.The app is ready to service requests quicker.

Reduced startup time: Native AOT applications can show reduced start-up times, in part due to the removal of Just-in-Time (JIT) compilation.

Reduced deployment time due to smaller images.

Smaller container images, for example in containerized deployment scenarios.

Reduced disk footprint: When publishing using native AOT, a single executable is produced containing the program along with the subset of code from external dependencies that the program uses.

Microsoft presented a bullet-point list detailing AOT benefits: Faster Startup, Smaller App (source: Microsoft).
