Hello,
Blazor Hybrid support is built into the .NET Multi-platform App UI (.NET MAUI) framework and can be built with Windows Presentation Foundation (WPF) and Windows Forms. You can choose MAUI if you want to build for iOS, Android app.
Additionally, by using .NET MAUI and Blazor together, you can reuse one set of web UI components across mobile, desktop, and web. That might be what you mean by "single coding, single html ui". Please refer to the doc- Reuse Razor components in ASP.NET Core Blazor Hybrid
For more details, you can refer to
