Syncfusion Trial License Key Link

Syncfusion provides a static Syncfusion.Licensing.SyncfusionLicenseProvider class. You typically register the key in the application's entry point:

For ASP.NET Core / Blazor / Web APIs: Place the registration in Program.cs (before builder.Build()).

using Syncfusion.Licensing;

var builder = WebApplication.CreateBuilder(args);

// Register your trial license key here SyncfusionLicenseProvider.RegisterLicense("YOUR_TRIAL_KEY_HERE"); syncfusion trial license key

builder.Services.AddControllersWithViews(); var app = builder.Build(); // ... rest of app

For Windows Forms (WinForms): Place it in Program.cs inside the Main() method, before Application.Run(). Syncfusion provides a static Syncfusion

public partial class App : Application
protected override void OnStartup(StartupEventArgs e)
SyncfusionLicenseProvider.RegisterLicense("YOUR_TRIAL_KEY_HERE");
        base.OnStartup(e);

Click on the license. You will see a text box containing the actual license key—a long, alphanumeric string (often 50-100 characters). There will be a "Copy to Clipboard" button. Use it. Do not share this key; it is tied to your account and email address.
