Hi Ehab,
Maybe you don't clearly understood what's MAUI is.
MAUI deployment target is not App Service or WebApp like App Service in Azure.
As Rob said, target deployement is only device app like Android, iOS, or Windows app.
Be carefull with MAUI Blazor app, even if the name contains Blazor, the target still remains a device app, but you can developp with web technologies like Blazor through WebView component in Maui.
Hope this answer helps you.
