Hello Gerald, first of all, thank you again for the job you do, I am happy to see that the channel is growing. I wanted to ask you if there is any way to set the camera to 9:16 while using it, and to add a usage timer at the same time.
In other words, is there any way to make the camera (using Xamarin Forms) behave in a similar way to how it does using Instagram Reels, youtube shorts, Tik Tok videos...

Hi Gerald, thanks for the videos. How do we get a DI viewmodels to a shell content page ? It seems shell pages do not support constructor injection. Thanks!

For the love of G-d, can you please make a tutorial on how to change the header bar colors of the WinUI and other shells in Maui Blazor? There is very little documentation on this. CommandBarBackgroundColor, etc? Thank you!

In my tests i can't work with DependencyInjection with Shell

'Cannot dynamically create an instance of type 'SOManager.Pages.LoginPage'. Reason: No parameterless constructor defined.'

You referenced an earlier video where you talk about host builders -- can you provide a link to that? Google's not being helpful (and it's too new for ChatGPT)
