Implementing Syncfusion Licensing

A comprehensive guide for generating, registering, and troubleshooting Syncfusion license keys across all platforms (WPF, Blazor, React, MAUI, Angular, Vue, ASP.NET Core, etc.).

Overview

Starting with version 16.2.0.x, Syncfusion introduced a licensing system that applies to:

• All evaluators using trial installers
• Paid customers using NuGet packages from nuget.org

If you use the evaluation installer or NuGet packages, you must register a valid license key in your application to avoid license validation messages.

Key Points:

• License keys are version and platform specific
• Registration is done offline (no internet connection required)
• Different from the installer unlock key
• Required for NuGet packages from nuget.org and trial installers
• NOT required for licensed installers (assemblies from licensed installation)
