Xamarin.Essentials VS FFImageLoading - Fast & Furious Image Loading

This one was one of the most annoying bugs in MAUI, and I solved it with this workaround taken from IeuanWalker on this thread.

This behavior is by design as it enables SSO with web identities but can be problematic in situations like this. Unfortunately, this kind of sign-out isn't a well-supported scenario, but you can read a good discussion on GitHub about it here: https://github.com/xamarin/Essentials/issues/1223.

I don't know where you're seeing "xamarin/Essentials", but that's a repo for code used in writing cross-platform mobile applications. That message refers to this issue: https://github.com/xamarin/Essentials/pull/1457. It's something that was fixed in the project 7 months ago.

First, add the Xamarin.Essentials NuGet Package to your projects. If you're using MVVM (Like we're doing in this example), you'll ideally want to install the Xamarin.Essentials.Interfaces NuGet Package

In the guide they have a link to a sample controller which does this, so I borrowed the code from it and ended up with this authentication controller method:

Xamarin.Essential >=1.5.3

Fortunately for us Xamarin developers, the Xamarin team and the community have created the Xamarin Essentials library and one of its utilities is the MediaPicker, which abstracts from you the logic for taking a picture with the camera or getting an image from the storage. You can read the documentation for the Media picker here.

I'm fairly sure that you could achieve this using https://github.com/luberda-molinet/FFImageLoading

Look into http caching. For MAUI / Xamarin Forms I recommend using FFImageLoading for displaying images from an URI. It handles caching automatically and I have used it in my projects.

I use FFImageLoading and it works well. Just make sure to manually add the latest SkiaSharp NuGet package to your Android project because otherwise SVGs won't render in Android 10+.

For image caching you might find https://github.com/luberda-molinet/FFImageLoading helpful in your endeavours. For FB login check https://devblogs.microsoft.com/xamarin/authentication-xamarin-essentials-aspnet/

2nd for https://github.com/luberda-molinet/FFImageLoading for image loading & caching needs. Supports SVGs which might be useful for map caching.
