What is it? 🚀

ComputeSharp is a .NET library to run C# code in parallel on the GPU through DX12, D2D1, and dynamically generated HLSL compute and pixel shaders. The available APIs let you access GPU devices, allocate GPU buffers and textures, move data between them and the RAM, write compute shaders entirely in C# and have them run on the GPU. The goal of this project is to make GPU computing easy to use for all .NET developers!

What can it actually do? ✨

Since a video is worth a thousand words, here's a showcase of some pixel shaders (originally from shadertoy.com), ported from GLSL to C# and running with ComputeSharp in a WinUI 3 sample app. You can use this library to create all sorts of things from scientific simulations, to animated backgrounds, audio visualizers and more!

Where is it being used? ✈️

ComputeSharp is production ready, and it's being used by several projects running on millions of devices!

Here's a showcase of some of them:

Screenshot	Project
	The Microsoft Store is a first party application that ships with Windows and allows users to discover, search and download digital content such as apps, games, movies and more. Starting from the January 2023 release, it is using ComputeSharp.D2D1.Uwp to leverage custom effects and pixel shaders to power several graphics elements in the application, such as the new app cards.
	Paint.NET is an image and photo editing application for Windows. Starting from its 5.0 release, it is using ComputeSharp.D2D1 as a core component of its architecture (in fact, ComputeSharp.D2D1 was initially developed specifically to support Paint.NET!). The library is used both internally to accelerate dozens of built-in effects using custom D2D1 pixel shaders, as well as for external plugins.
