I’ve been exploring ASPSnippets for learning ASP.NET techniques and examples. However, I’m curious—what are the key new features or updates in ASP.NET Core for 2025 that developers should be aware of nowadays?

I’ve heard about enhancements like minimal APIs, improved performance, better diagnostics, and new support for modern frameworks like Blazor and GraphQL. Could someone summarize the most important updates or point me toward the latest official documentation?

Hi,

ASP.NET Core for 2025 will see continued improvements in performance, enhanced JavaScript integration, and expanded OpenAPI support. Key areas of focus include faster component rendering, simplified JavaScript interop in Blazor, and improved OpenAPI specifications generation and customization. Additionally, expect updates to authentication scaffolders and continued cross-platform support with .NET MAUI.

Key Updates and Innovations:

Faster Component Rendering:

Expect significant performance improvements, particularly for larger applications, with faster component rendering in Blazor.
Improved JavaScript Integration:

Blazor will make it easier to work with JavaScript libraries, allowing for better reuse of existing JavaScript code in web applications.
OpenAPI Enhancements:

ASP.NET Core 9 will introduce new features to simplify the process of generating and customizing OpenAPI (formerly Swagger) specifications, enhancing API documentation and exposure, according to Techcronus.
Authentication Scaffolders:

New and updated scaffolders will facilitate the addition of authentication to apps, including support for passkeys and Entra ID.
.NET MAUI Integration:

ASP.NET Core will continue to support cross-platform mobile app development through .NET MAUI, allowing developers to build apps for Android, iOS, Windows, and macOS from a single codebase, according to Saasverse.
Blazor Enhancements:

Continued focus on enhancing Blazor, enabling developers to use C# for rich browser experiences without relying heavily on JavaScript.
Servicing Updates:

Regular servicing updates will continue to address non-security and security issues in both .NET and .NET Framework.
Kestrel Improvements:

The high-performance, cross-platform Kestrel web server will likely see further optimizations and enhancements.
Visual Studio and VS Code Integration:

Expect continued improvements in the tooling within Visual Studio and Visual Studio Code for ASP.NET Core development.

Other Notable Points:

Cross-Platform:

ASP.NET Core is fully cross-platform, supporting Linux, Windows, and macOS.
Open Source:

It's an open-source framework, making it free to use and contributing to its community-driven development.
Component Rendering:

Changes in rendering for components like AIPrompt, DockManager, ExpansionPanel, Gantt, and Grid will be introduced.
Security:

Built-in security features for authentication, authorization, and data protection are a core part of ASP.NET Core.
Testing:

The framework provides tools for creating unit and integration tests.
