Requires robust error handling, cancellation tokens, and potentially reactive programming (Rx.NET) to manage the data flow.\n2. **3D Viewport Performance & Cross-Platform Compatibility:** Getting a performant, consistent 3D viewport across desktop (OpenGL/DirectX) and mobile (Metal/OpenGL ES) in C# is tough.
