Introducing .NET Multi-platform App UI (MAUI) VS Mono

I am migrating XF app into MAUI and writing a simple Navigation framework because Prism doesn't work well and I didn't use anything advanced anyway. So, I am surfing the code of MAUI to intercept all the back buttons, etc. I haven't found a single mention of apis related to predictive back "RegisterOnBackInvokedCallback", "OnBackInvokedDispatcher", "OnBackPressedDispatcher", "AddCallback", "android:enableOnBackInvokedCallback" Also I don't see any issue on github that would say "Support Android Predictive back". Only one kinda related https://github.com/dotnet/maui/issues/8680

Below issue is still reproducing in Maui .net7.0 version also. #10163

I do share your skepticism of Microsoft, but it looks like the economics and cash flow dynamics have changed drastically after the advent of the cloud.

Microsoft is more focused on getting developers onto its ecosystem and help them with open source projects with the hope that they will use its Azure cloud services and bring in the money.

My skepticism is a bit relaxed now and I have no qualms using .NET.

I hope I am not wrong.

It's a bit of a hit and miss as of today. CLI, back-end and natively compiled libraries (think dll/so/dylib or even .lib/.a - you can statically link NAOT binaries into other "unmanaged" code) work best, GUI - requires more work.

Avalonia[0] and MAUI[1] have known working templates with it, but YMMV.

I think the fundamental issue is that desktop Linux is way too fragmented. Not only just GTK2/3 and Qt but you have GNOME, KDE, XFCE, Cinnamon and then you have X11, Xorg, Wayland...

To be honest, all those craps are why desktop Linux never took off. I'm very safe to say MAUI for Linux will eventually renders components off its own using framebuffer and hardware acceleration APIs such as OpenGL or Vulkan just because of the market fragmentations...

If desktop Linux truly wants to get the attention, it will need to unify. Fixing dependency hell using Flatpak is the right direction.

There is an existing old fork of MAUI for Linux that uses GTK: https://github.com/jsuarezruiz/maui-linux

First I came across this Github issue: https://github.com/dotnet/maui/issues/9687 - According to this issue, this is a known bug for MAUI iOS, but it works OK for MAUI Android. As I said, I target Android only and I have the exact same issue. It's apparantly fixed with some of the latest versions for MAUI but the problem still occurs to me even with MAUI version:

I saw this and tried to imitate (ofc my lack of experience wouldn't allow me to do it in the exact way). Already found some documentation that allowed to understand better. Thanks for the insigh.

I implemented the Auth controller following this sample code from Microsoft.

In the video you basically install .NET 7.0 SDK with the deb packages from Microsoft repos AND mono deb packages from repos laid out in https://www.mono-project.com/ apart from Unity and VS Code. And then you configure VS Code so that it always uses Mono installed in the system (not Unity Editor's own instance???)

4- Any user-side telemetry would be in the MS .Net framework, which is not used when you selfhost as .net based stuff like Jellyfin use Mono, which is fully open-source and independent (https://www.mono-project.com/)

Did they intentionally name it after a widely used, well known programming framework[1], or did they want to guarantee, I dunno, that they will fly way, way under the radar? I thought it was bad form to name a new programming language 'Cedar', but at least the other Cedar isn't actively developed, unlike the other Mono.

.NET 4.8.1 and earlier do not install on Linux. Unless you want to play around with Mono (your mileage may vary): https://www.mono-project.com/

They have deceived you. https://www.mono-project.com/ I seriously don't know how well wine can deal with newer .NET winforms

It also gained a lot of more popularity and success after the release of the open source implementation of it called Mono.

Hey, I'm working on a C++ game engine in VS Code and wanted to add C# scripting, so I'm trying to install Mono. I already got SDL2 working with CMake, but I'm having trouble setting up Mono because it doesn't seem to have any out of the box CMake support.

Microsoft already has universal cross flatform low level spyware as C# and .NET (which is used by tons of even native linux games, especially made with Unity), mono is sponsored by Microsoft and has telemetry. Wine also uses mono.

And then installs proprietary steam, spotify, vscode and develops on C# for linux with telemetry even in mono runtime...
