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

> There's definitely things they tried to improve on that... weren't really improvements. The way "assemblies" are matched in .NET is much more sophisticated- the goal there was to try to kill DLL hell. It evolved into the Global Assembly Cache, which is sort of the Windows Registry of DLLs. Not a huge fan of those bits.

The Global Assembly Cache did not make the jump to the modern .NET (Core). There was the thing called `dotnet store`, but it’s broken since .NET 6: https://github.com/dotnet/sdk/issues/24752

The assembly redirection hell has also been greatly reduced there.

I do the same.

I have a small write-up here: https://chrlschn.dev/blog/2023/10/end-to-end-type-safety-wit...

You get end-to-end type safety (even better once you connect it to EF Core since you get it all ways to your DB).

With this setup with hot-reload (currently broken in .NET 8 [0]), productivity is really, really good. Like tRPC but with one of the most powerful ORMs out there right now.

Noticed an open issue just now.

You're thinking of https://github.com/dotnet/sdk/issues/22247

That's a twisted and wrong narrative

Unity like refers to a Editor driven approach

Unity became popular with its moonscript language (javascript like), they then ditched it to focus on C#, but what propelled unity to what it is today is the Editor driven approach, not c#, not DOTS

They are forced to transpile C# to C++ via IL2CPP as a result to target consoles/mobiles

C# is a disease when it comes to console/mobile support

It's a substantial dependency, quite heavy

And you are not free of unity like fuck ups, it's a microsoft language after all:

https://github.com/dotnet/sdk/issues/22247

And let's not forget when they changed the license of their debugger overnight to prevent people from using it in their products (jetbrains for example)

And them deprecating open source tooling to a proprietary/closed one for vscode (c# devkit)

Let's be careful when we recommend evil as an alternative to evil ;)

The script can be found at the end of the thread here https://github.com/dotnet/sdk/issues/8742

Another difference you might be surprised by is that the .NET tooling by default collects various data from your system and sends it to Microsoft [1]. If you want to avoid this (and still want to use .NET) you'll have to make sure that the environment variable DOTNET_CLI_TELEMETRY_OPTOUT is set in all contexts before touching anything.

SDK Pull Request

Pretty sure the final file referenced here https://github.com/dotnet/sdk/issues/8742 is the one I am thinking of.

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.
