.NET MAUI is coming to Linux and the browser

In the .NET ecosystem, I have noticed people to shame .NET MAUI because Microsoft themselves don't use this framework - Microsoft Team is built on Electron and not MAUI.

Why build a product on MAUI when Microsoft aren't too sure about it.

That has been a problem since forever. Microsoft themselves rarely used the tools they gave to developers. SourceSafe, MFC, WPF and the .NET frameworks that followed were only for 3rd party devs. And when they used these tools, the software usually got worse. One example was Visual Studio. 2008 was really nice with great customization and good performance. Then they wrote 2010 with MFC and it was slow and lost tons of features.

I think it’s better on the server side with ASP.NET.

As far as I have heard MAUI is pretty buggy and has lost momentum. It will probably go on the long list of basically abandoned .NET UI frameworks

You are mixing your UI frameworks and versions. VS 2010 is written in WPF. WPF is / was Windows Vista's and 7's UX. Old Control Panel in Win 10/11 still is WPF. All the wizards like ClearType wizard is WPF. MFC is much older (1992).

Unfortunately Microsoft likes to jump into bandwagons and many engineers at the company seem to like to reinvent stuff rather than adopt. WPF, WinUI2 and WinUI3 all share the same Xaml based structure. So they could have adopted WPF.

It is not that Microsoft doesn't develop advanced UIs with their frameworks. WPF is still well-used by Windows and other Microsoft utilities like Windows Terminal. They are just stupidly abandoning their built up bases for silly industry fads.

They jumped into tablet / touchscreen / hybrid-mobile-desktop bandwagon in late-2010s and tried to force WinUI as an UWP-only feature. It resulted in low adoption. They didn't adopt WPF to have same theming.

When WinUI2 failed, they tried to make modern C++ a reality and tried to remove UWP restrictions which is a good decision. However they diverted quite a bit resources into AI slop generation now and WinUI3 just languishes.

Same for MAUI. They tried to get into multi-platform, multi-device framework as a way to generate leads into Microsoft ecosystem.

They try to use various frameworks and UI stuff to get people hooked into the ecosystem and find ways to upgrade them into Azure and M365 customers. It is meaningless and tiring. All of those could be only WPF.

It is like Google and its many Bazel-like build systems (but not full Bazel) for each of Chrome, Fuschia and Android.
