Show HN: Vello's high-performance 2D GPU engine to .NET

Highlights

• End-to-end Vello 2D GPU rendering on top of the wgpu 3D backend with DX12, Vulkan, and Metal targets auto-negotiated at runtime.
• First-class desktop framework coverage: Avalonia surfaces, WPF and WinForms hosts, WinUI/Uno adapters, plus direct winit bindings for headless or custom shells.
• Production text stack that pairs the new VelloSharp text helpers with a HarfBuzzSharp-compatible shim and Skia interop layers for migration and regression testing.
• Vertical solutions for visualization and operations: charting engines, gauges, SCADA dashboards, and the editor toolchain all updated to the new runtime.

Each meta package above bundles the RID-specific NuGet packages (for android-arm64, browser-wasm, ios-arm64, iossimulator-x64, linux-arm64, linux-x64, osx-arm64, osx-x64, win-arm64, and win-x64) that are emitted by the release pipeline. Consume the meta package when you need full platform coverage or reference an individual RID package to keep your distribution lean.

Getting started

• Install the primary renderer: dotnet add package VelloSharp.
• Add the framework bridge you need, for example dotnet add package VelloSharp.Avalonia.Vello, dotnet add package VelloSharp.Integration.Wpf, or dotnet add package VelloSharp.Integration.WinForms.
• Pull in Skia or text shims when migrating existing pipelines: dotnet add package VelloSharp.Skia.Core and dotnet add package VelloSharp.HarfBuzzSharp.
• When targeting a specific runtime, reference the matching VelloSharp.Native.*.<rid> package or rely on the meta package to light up every supported platform.
