For .NET based ones, WPF or if feeling adventurous since it is still in preview MAUI (which uses WinUI 3.0 + WinAppSDK on Windows).
WinAppSDK is the new name for Project Reunion.
UWP is supposed to be deprecated and on the way out, but given the slowness of WinUI 3.0 improvements, apparently even Microsoft teams are still using it, e.g. the new Windows 11 appstore.
For those using C++, on the MS GUI stack, as rediculous as it might seem, MFC is still the best they can do.
There was a short while where C++/CX seemed to be Microsoft catching up with C++ Builder in regards to RAD tooling for C++ developers on Windows, but C++/WinRT mutiny killed that dream.
So all things considered, Win32/MFC for C++ devs, Win32/WPF for .NET ones, unless feeling adventurous and not afraid of code rewrites.
