- licensing
- to validate it with license, 2 ways
1. entry point file 
```cs
using Syncfusion.Licensing;

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        // Register the Syncfusion license
        SyncfusionLicenseProvider.RegisterLicense("YOUR_LICENSE_KEY"); // Replace with your actual license key
        
        // Other service registrations
        services.AddControllersWithViews();
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        // Existing code for middleware configuration...
    }
}
```

2. in razor pages
```cshtml
@using Syncfusion.Licensing
@{
    SyncfusionLicenseProvider.RegisterLicense("YOUR_LICENSE_KEY"); // Replace with your actual license key
}
```
