Show HN: Immediate-mode GUIs in C# – I wrote an eBook on using Dear ImGui in C# Hi HN, I’ve been using Dear ImGui with C# (via ImGui.NET) to build some open source game/audio tools and applications. I was looking for something fast and flexible and immediate-mode GUIs work surprisingly well. You can make full blown applications that weight just a bunch of MB and being ImGui render agnostic, they can be truly cross-platform. I noticed there’s very little C#-focused documentation or guides so I decided to gather what I’ve learned into an ebook of just under 100 pages, aimed at helping others who may be interested, to get up and running quickly. The ebook contains code snippets followed by pictures and I've released a few chapters for free on GitHub: https://ift.tt/U6gAzb4 This is the first "book" I write and I hope it can be useful and spark some interest in an alternative way to develop C# applications. Or if you're not interested in it, that I made you discover something new. Thank You for reading. Alex https://ift.tt/U6gAzb4 May 2, 2025 at 12:54AM
