Note: MAUI Blazor allows you to create applications that run on multiple platforms, however, this tutorial only covers creating an application that runs on Windows. In addition to running our applications on Windows, MAUI Blazor allows us to run our applications on Android, iOS, and MacOS. MAUI Blazor allows us to create applications that run natively on the operating system (rather than in a web browser).
