Adding a .NET MAUI SignaturePad reference

Syncfusion .NET MAUI controls are available in Nuget.org. To add .NET MAUI SignaturePad control to your project, open the NuGet package manager in Visual Studio, search for Syncfusion.Maui.SignaturePad and then install it.

Step 1: Create a .NET MAUI application project in Visual Studio 2022.

Step 2: Add the Syncfusion.Maui.Core Nuget to the project from nuget.org.

Step 3: In the MauiProgram.cs file, register the Syncfusion.Maui.Core handler as follows.

C#

using Syncfusion.Maui.Core.Hosting;
namespace SignaturePad;
public static class MauiProgram
{
    public static MauiApp CreateMauiApp()
    {
        var builder = MauiApp.CreateBuilder();
        builder
            .UseMauiApp<App>()
            .ConfigureSyncfusionCore()
            .ConfigureFonts(fonts =>
            {
                fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
            });
        return builder.Build();
    }
}
