Mescius .NET 10 Support and Highlights

The .NET platform has continually evolved into one of the most powerful and reliable development ecosystems globally since its debut nearly 25 years ago. From web and cloud services to desktop and mobile apps, this framework has been the cornerstone of productivity and innovation for developers everywhere.

Now, over two decades later, Microsoft introduces .NET 10, ushering in another wave of performance gains, developer productivity upgrades, and broader cross-platform integration. With every major .NET release, it’s crucial that the tools and UI libraries developers rely on evolve simultaneously. Our team has been testing the ComponentOne control libraries throughout the entire .NET 10 preview release cycle to minimize surprises. That’s why you can confidently use our latest WinForms, WPF, Blazor, WinUI, and MAUI components in new .NET 10 applications today and even begin to migrate your existing applications to the latest version.

Upgrading to .NET 10

Every new .NET release is more than a version update; it’s an opportunity to make your applications faster, safer, and easier to maintain. With .NET 10, Microsoft drives home three core goals: speed, consistency, and developer empowerment.

From the runtime to the SDK, nearly every layer of the platform has been refined to help developers focus less on boilerplate and more on advancement. As a long-term support release, upgrading to .NET 10 ensures teams can confidently build projects that will remain stable and secure for years.

Key Highlights of .NET 10

Smarter Runtime and Faster Execution

The JIT compiler has been upgraded once again. Expect better inlining, more aggressive loop optimizations, and a sharper focus on memory efficiency. For high-throughput workloads, such as web APIs, background services, and real-time systems, these minor adjustments yield substantial performance improvements.

Streamlined Deployment and Lighter Apps

.NET 10 supports lighter-weight publishing by improving native Ahead-of-Time (AOT) builds, enabling enhanced single-file apps, trimming unused dependencies, and reducing runtime startup and footprint—making deployment leaner, faster, and better suited for containers, microservices, and edge environments.

Tooling and SDK Refinements

The .NET SDK enhances the overall developer experience through smarter, more flexible tooling and improvements. The new release streamlines project setup and build processes, simplifies automation and packaging workflows, and refines integration with popular development environments, equipping developers with the features they require to build, test, and deploy applications efficiently.

Expanded Library and API Updates

Library enhancements span cryptography (thumbprint search, PEM processing, and post-quantum algorithms), globalization (numeric string comparisons and DateOnly support), performance-tuned collections and ZIP handling, richer JSON serialization options, telemetry improvements, WebSocketStream for easier low-level streaming, and TLS 1.3 support for macOS clients. These updates sharpen performance and offer more granular control for modern application patterns.

Broader Ecosystem

.NET 10 extends its reach throughout diverse environments with updates across all major platforms:

• WinForms: The Windows Forms stack introduces shared clipboard APIs with WPF and ports UITypeEditors from older frameworks, ultimately enhancing both designer and runtime productivity.
• WPF: This platform boasts performance tweaks, Fluent theme enhancements, and bug-fix refinements, delivering a smoother and more polished desktop UI experience.
• ASP.NET Core: Web- and cloud-oriented apps benefit from expanded Blazor capabilities, broader OpenAPI integration, improved minimal APIs, and richer identity support.
• .NET MAUI: Cross-platform mobile and desktop apps benefit from improved modular workload packaging, enhanced media and WebView handling, and refined support for Android API levels 35 and 36.

The result? A more unified experience, whether you’re developing for desktop, web, mobile, or the cloud.

Developer Experience and Productivity

With an overarching theme of efficiency (both in runtime performance and developer workflow), .NET 10 continues to ease frustration in daily development tasks with improved build logs and simplified testing integrations. New language features introduced in C# 14 hone developer processes with extension properties and static extension members, the new field keyword for concise backing properties, implicit conversions between arrays and spans, richer lambda parameter modifiers, and improved support for unbound generic types.

Spend less time configuring and more time coding in a secure and stable environment. Developers building large-scale applications will find reliable servicing and lasting support, improving project maintenance.

ComponentOne .NET 10 Support Details

Delivering over 400 professional-grade .NET UI controls, ComponentOne simplifies the demands of modern application development, offering .NET datagrids, charts, pivot grids, and advanced input components. Immediately available with the .NET 10 release, developers can take advantage of:

• Seamless .NET 10 compatibility across major frameworks, including WinForms, WPF, Blazor, WinUI, and .NET MAUI.

Migrating to .NET 10 with ComponentOne

Are you ready to upgrade your stack? The ComponentOne team is committed to delivering quick and seamless migration to .NET 10 with a few simple steps for uninterrupted project development:

1. Audit your dependencies – List the ComponentOne controls you rely on and confirm their updated package versions. Ensure you are using the 2025 v1 Maintenance Release #2 builds or later.
2. Update via NuGet – Install the latest .NET 10-ready libraries directly from nuget.org, or wait until our major release next month for the complete install. Please note that .NET 10 support for ASP.NET Core will be verified by ComponentOne’s 2025 v2 release in December 2025.
3. Run compatibility tests – Verify UI interactions like themes, clipboard access, drag-and-drop, and serialization.
4. Leverage support – Reach out to ComponentOne’s support team if you encounter migration obstacles. A complete release history for each platform is available in our documentation.

By upgrading in tandem, you can take advantage of the speed, stability, and UI modernization that both Microsoft and ComponentOne deliver. When you combine the power of .NET 10 with ComponentOne’s feature-rich UI controls, you get the best of both worlds: cutting-edge performance backed by a reliable, battle-tested design system. 

New Dark Mode in WinForms

One of the exciting new features in this release is available through the Windows Forms platform. If your application targets .NET 10, you can now conveniently set the Application Color Mode with only one line of code.

Application.SetColorMode(SystemColorMode.Dark);

This adjusts all system brushes; for example, SystemColors.Window becomes a dark color when the SystemColorMode is set to Dark. ComponentOne controls heavily rely on these system colors, so you will notice this works for simple controls like FlexGrid and Input.

For richer controls that require more advanced brushes, such as the Scheduler and Data Filter, you will want to combine the Dark Color mode with one of our dark themes, like Office 365 Black. Simply add a reference to C1.Win.Themes and then add two lines of code to set the theme to your application (after InitializeComponent).

if (Application.ColorMode == SystemColorMode.Dark)
{
    C1Theme theme = C1.Win.Themes.C1ThemeController.GetThemeByName("Office365Black", false);
    C1ThemeController.ApplyThemeToControlTree(this, theme);
}

Conclusion

Whether you’re refining enterprise dashboards, building responsive web portals, or crafting data-driven desktop apps, ComponentOne’s support for .NET 10 accelerates development while maintaining top-tier quality.

This release sets the stage for the next chapter of development, paving the way for faster builds, leaner apps, and a more seamless developer experience.
