I'd like to get started doing screen capture (of video content) on Windows 10 (specifically on a laptop), using C#. My preference is to code in a Windows Forms application, but I'd consider a UWP application if that was easier.
There's a lot of material on the web, but I'm not sure where to start as it's usually older content or about DirectShow which requires the use of C++ (e.g. "Windows Media" → "The Windows Development Reference: Audio and Video in Desktop Apps" → "Audio and Video").
There's the Stack Overflow question "How can I capture the screen to be video using C# .NET?", but that's from 2010 and uses (presumably) depreciated software versions as the core.
