Syncfusion Blazor Components End Support for .NET 6 and 7

The Syncfusion Blazor component library offers over 90 responsive, lightweight components, including data visualizations like DataGrid, 50+ Charts, and Scheduler, for building modern web apps.

Currently, our Blazor components support .NET 6, .NET 7, .NET 8, and .NET 9. However, with our upcoming 2025 Volume 1 release, we will focus exclusively on .NET 8 and .NET 9. This decision aligns with Microsoft’s support lifecycle and ensures our users can utilize the latest features and optimizations available in the Blazor ecosystem.

The announcement: Blazor components optimized for the future

Starting with our 2025 Volume 1 release, tentatively scheduled for March 2025, Syncfusion Blazor components will exclusively support .NET 8 and .NET 9. Discontinuing support for .NET 6 and .NET 7.  This approach allows us to:

1. Maximize the potential of the latest Blazor rendering models, including Blazor Server, WebAssembly, and the new Blazor Web App.
2. Optimize our components for enhanced performance, leveraging .NET 8’s significant speed improvements and anticipating further enhancements in .NET 9.
3. Implement advanced security measures and automated updates with Dependabot to ensure improved stability and compatibility with the latest security protocols and best practices.

Aligning with Microsoft’s vision

We are aligning our support schedule with Microsoft’s timeline:

• .NET 6 LTS: Support ended in November 2024.
• .NET 7: Support ended in May 2024.
• .NET 8 LTS: Supported until November 2026.
• .NET 9: Estimated support until May 2026.

Impact on Blazor developers and transition plan

.NET 6 and .NET 7 users

If you’re currently using .NET 6 or .NET 7 with Syncfusion Blazor components, we strongly recommend upgrading your apps to .NET 8 or .NET 9. This upgrade will not only ensure you continue receiving support from Syncfusion but will also unlock significant performance improvements and new Blazor features.

• March 2025: Official discontinuation of support for .NET 6 and .NET 7 in Syncfusion Blazor components.

This timeline allows developers to plan and execute their migration strategies effectively.

Updates to Blazor demos and documentation

With the 2025 Volume 1 release, our Blazor demos and documentation will also provide in-depth guidance on Syncfusion components, incorporating the latest features of .NET 8 and .NET 9.

Preparing your Blazor apps for transition

To ensure smooth migration, we recommend following Microsoft’s official upgrade guides:

• Migrate from ASP.NET Core 7.0 to 8.0
• Migrate from ASP.NET Core 8.0 to 9.0

Key steps for Blazor developers

1. Update your project’s target framework to .NET 8 or .NET 9.
2. Review and update package references, including Syncfusion packages.
3. Address any breaking changes in Blazor.
4. Test your app thoroughly, especially areas with heavy JavaScript interop or custom rendering logic.

ASP.NET Core controls

The same strategy applies to our ASP.NET Core products alongside Blazor. With the release of 2025 Volume 1, Syncfusion ASP.NET Core controls will support .NET 8 and .NET 9.

Conclusion: Embracing Blazor’s bright future

By focusing our efforts on .NET 8 and .NET 9, Syncfusion is positioning our Blazor components at the forefront of web development. This strategic shift enables us to deliver exceptional performance, innovative features, and robust security to our users.

We invite all Blazor developers to join us on this journey. By upgrading your apps, you will not only ensure ongoing support but also unlock a world of possibilities in modern web development with Blazor.

Our team is committed to supporting you through this transition. We’ll provide additional resources, migration guides, and direct support to ensure your Blazor projects thrive in this new era.
