Posted by msmash on from the moving-forward dept.

An anonymous reader writes: At its Microsoft Connect(); 2018 virtual event today, Microsoft announced the initial public preview of Visual Studio 2019 -- you can download it now for Windows and Mac. Separately, .NET Core 2.2 has hit general availability and .NET Core 3.0 Preview 1 is also available today.

At the event today, Microsoft also made some open-source announcements, as is now common at the company's developer shindigs. Microsoft open-sourced three popular Windows UX frameworks on GitHub: Windows Presentation Foundation (WPF), Windows Forms, and Windows UI XAML Library (WinUI). Additionally, Microsoft announced the expansion of the .NET Foundation's membership model.

  1. Notes and caveats by Daltorak · · Score: 5, Informative

    A lot of people around here don't keep up with Microsoft technology, so here's a few notes and caveats:

    1. The Windows and Mac versions of Visual Studio 2019 are completely separate products built from different code bases. They share compilers and .NET Core stuff, and a lot of work is going into making the editors feel the same. But you can't actually use Visual Studio for Mac to work on classic Win32 / .NET Framework applications.

    2. Windows Forms and WPF are also Windows-only technology, and that isn't changing even though they'll work with .NET Core 3. There are way too many hooks and dependencies on Windows-specific technology (e.g. DirectX, text rendering, themes, handles) for these to be made into cross-platform applications without major rearchitecting work. In other words, don't wait up for them to produce a competitor to Qt....

    3. The source code for Windows Forms and WPF have actually been available as "reference source" for more than a decade, so there are no real surprises to be discovered here.

    4. All three libraries are being hosted on Github and are licensed under MIT. These aren't mirrors -- the teams at Microsoft will actually be doing their everyday work in the open on Github. Unfortunately, the full commit history didn't come along for the ride.

    5. One of the nice little improvements here is the ability to package your own version of Windows Forms with your app, instead of relying on whatever is installed with the system. .NET Core doesn't (currently) support static linking so it'll still have to exist as a DLL file beside the EXE.
