Common

Features

  • Syncfusion ASP.NET MVC now supports individual NuGet packages, allowing developers to install only the required components. This reduces application size and improves dependency management.

  • Introducing Standalone UI SDKs:

    We are introducing Standalone UI SDKs to provide greater flexibility in how you license and build your applications.

    In addition to the UI Component Suite, you can now purchase individual SDKs for:

    • Grid SDK
    • Chart SDK
    • File Manager SDK
    • Gantt SDK
    • Scheduler SDK
    • Diagram SDK
    • Rich Text Editor SDK

    Whether you need a single specialized component or a comprehensive UI suite, you can now choose the product that best fits your application requirements and budget.

    Starting with this Volume 2 2026 release, Gantt, Scheduler, Diagram and Rich Text Editor components are now available as standalone SDKs and licensed separately. While the UI component suite continues to provide the comprehensive collection of the remaining high-performance UI components.

    Note: This change applies to the new product purchases only. Existing customers will continue to receive access to all the UI components, including Gantt, Scheduler, Diagram and Rich Text Editor, according to their current licensing. No changes are required for the existing customers.
