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

Sometimes when a detail of Windows isn't documented, the Wine source code can be useful. Have you tried looking at it for details of win64 SEH? For example:

https://github.com/wine-mirror/wine/blob/master/dlls/ntdll/e...

https://github.com/wine-mirror/wine/blob/master/dlls/msvcrt/...

Source code: https://github.com/wine-mirror/wine/tree/master/programs/wor...

It's Wine with some special sauce (Apple couldn't reuse VKD3D because they chose to invent Metal rather than stick with OpenGL/Vulkan so they had to build their graphics translation themselves). Crossover is built on the same technology. In fact, Apple's brew script literally links to Crossover's sources: https://raw.githubusercontent.com/apple/homebrew-apple/main/...

Things like the crypto API should be implemented if you can find the reference for your specific API calls here: https://github.com/wine-mirror/wine/tree/master/dlls/crypt32

Apple's version of Wine is aimed at developers, though. It shouldn't take too long for someone to make an app or script to easily set up environments with the developer runtime, but I doubt they'll support it as well as Valve supports Proton. If your application of choice doesn't need any fancy graphics, there's a decent chance Wine/Crossover can already run it anyway, no need to mess with Apple's SDK.

With the M2 Max outputting 28fps at 1080p (screenshot linked), I wouldn't expect too much from the gaming performance of this thing, though.

Not the OP, but Github's stats on https://github.com/wine-mirror/wine say the current Wine codebase is 95.1% C, 0.3% C++

Take a look at Wine's commit log. It's really well curated. https://github.com/wine-mirror/wine/commits/master

Fixes Overwatch 2 game freeze after a few seconds in game. After a long bisect it was found that wine-mirror/wine@4bf9d24 from upstream wine wine 7.13 and higher needed to be backported.

git clone https://github.com/wine-mirror/wine \ cd wine \ ./configure \ make \ make install \ wine ./Anomaly.exe

Well, I personally can't confirm nor deny that (the only "old" game I play is Plants vs Zombies (2009), and surprisingly it still works great with latest Proton). But the reality is that Wine/Proton are very large and complex projects, developed by pretty much just reverse engineering Windows; Couple this with the fact that a lot of changes happen in-between versions (especially in Wine), and even though an one-line change fixes an issue, it might end up breaking something, elsewhere. My point is, it's almost inevitable not to break stuff eventually. This is why Valve gives us older Proton versions to choose from.

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.

While this is the quite endorsed by the community: https://github.com/dotnet/maui/discussions/339

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.
