Win2D
Win2D is an easy-to-use Windows Runtime API for immediate mode 2D graphics
rendering with GPU acceleration. It is available to C#, C++ and VB developers
writing apps for the Windows Universal Platform (UWP). It utilizes the power
of Direct2D, and integrates seamlessly with XAML and CoreWindow.

Code Example
To give you a flavor of what the code looks like, here is a snippet of XAML:
xmlns:canvas="using:Microsoft.Graphics.Canvas.UI.Xaml"
<Grid>
<canvas:CanvasControl Draw="canvasControl_Draw" ClearColor="CornflowerBlue" />
</Grid>
and C#:
void canvasControl_Draw(CanvasControl sender, CanvasDrawEventArgs args)
{
args.DrawingSession.DrawEllipse(155, 115, 80, 30, Colors.Black, 3);
args.DrawingSession.DrawText("Hello, world!", 100, 100, Colors.Yellow);
}
or C++/CX:
void MainPage::CanvasControl_Draw(CanvasControl^ sender, CanvasDrawEventArgs^ args)
{
args->DrawingSession->DrawEllipse(155, 115, 80, 30, Colors::Black, 3);
args->DrawingSession->DrawText("Hello, world!", 100, 100, Colors::Yellow);
}
or C++/WinRT:
void MainPage::CanvasControl_Draw(CanvasControl const& sender, CanvasDrawEventArgs const& args)
{
args.DrawingSession().DrawEllipse(155, 115, 80, 30, Colors::Black(), 3);
args.DrawingSession().DrawText(L"Hello, world!", 100, 100, Colors::Yellow());
}
or VB:
Sub canvasControl_Draw(sender As CanvasControl, args As CanvasDrawEventArgs)
args.DrawingSession.DrawEllipse(155, 115, 80, 30, Colors.Black, 3)
args.DrawingSession.DrawText("Hello, world!", 100, 100, Colors.Yellow)
End Sub
Using Win2D
The documentation explains how to install Visual
Studio, add the Win2D NuGet package to your project, and get started using the API.
Building Win2D from source
Requirements
- Visual Studio 2019 16.2 with Tools for Universal Windows Apps 15.0.27428.01 and Windows SDK 18362
Clone Repository
- Go to 'View' -> 'Team Explorer' -> 'Local Git Repositories' -> 'Clone'
- Add the Win2D repository URL (https://github.com/Microsoft/Win2D.git) and hit 'Clone'
Build NuGet Packages
- Launch 'Developer Command Prompt for VS2019'
- Change directory to your cloned Win2D repository and run 'build'
Point Visual Studio at the resulting 'bin' directory
- In Visual Studio, go to 'Tools' -> 'NuGet Package Manager' -> 'Package Manager Settings'
- Choose 'Package Sources'
- Click the '+' button to add a new source
- Set 'Name' to 'Win2D' (or a name of your choosing)
- Set 'Source' to the full path to the 'bin' directory (inside your cloned Win2D repository)
- Click the 'Update' button
- Click 'OK'
Locally built versions of Win2D are marked as prerelease, so you must change the 'Stable
Only' setting to 'Include Prerelease' when adding them to your project.
Legacy support for Windows 8.1
Win2D 1.21.0 was the last release to support the Windows 8.1 and Windows Phone 8.1
platforms. From Win2D 1.22.0 onward, only the Windows Universal Platform (UWP) is
supported.
Legacy Win2D support for Windows and Phone 8.1 is available as a
NuGet package and from the
win81 branch on github.
