Cocoa developer here. What APIs/tools for writing a commercial Windows app?

Great question.

I have tried to understand this myself without a good answer.

Google chrome UI team had an article on how they didn't find good user controls or windowing system for Windows and had to write everything from scratch. The chromium source was way too complex for our needs so we ended up not exploring it.

Still open source GUI code. (So good open source GUI code in Windows has been hard to find, but that's a good bet).

You probably want your app to run on both XP and 7 ?

8 is vaporware as a target platform for releasing and scheduling purposes.

We started with Windows Forms for our work because we were familiar with the code. (We did use MVC pattern using MVCsharp). We meant to switch to WPF but we never made the leap. There are UI-controls you can buy (with source) which you can use as plug and play. There are a few popular vendors.

Windows Forms still look ugly (lipstick on a pitbull kind of thing)

WPF is supposed to be a panacea with XAML being markup and that letting you generate "fluid-UI" just like HTML with auto-resizing and scaling as in the browser for your web-app.

I'd explore WPF and figure out a MVC-pattern library for separation of concerns.

Hope this helps.

Thanks.

No, we're only targeting Windows 7 and up. This is a personal itch we're scratching. The commercial angle is a bonus ... for now!

What about, say, 4 to 6 months from now? That's the timeline we're thinking of right now.

I've read a bit about WPF. It sounds amazing. My major concern is: will it be actively developed in the future? I know Microsoft will never break backward compatibility, but will they keep adding new things to WPF? That's what's been bugging me.

But I guess having this discussion is fruitless. After all, what choice do we have besides WPF?

There are many people out there wondering the same thing - the Win8 HTML/JS announcement has thrown the rumor mill into a frenzy.

My advice - wait one month for BUILD (http://www.buildwindows.com/).

(disclosure - I work at Microsoft)

Ah. I suppose we'll start working on the core of our application now and decide on the UI later.

Thanks!

Pick up Visual Studio Express (Visual C# Express) for starters:

Windows Forms is NOT deprecated, nor is WPF.

The good news is that you can jump in anywhere and the skills you learn will help you down the road. WinForm and, even moreso, WPF programming will help you if you wish to jump into Silverlight.

It's all the same crap and you'll be able to transition easily. I've been playing with WPF and Silverlight as of late. Perhaps you should start with WPF.

You can write your app in whatever today and it probably won't be deprecated for at least a decade, but in the current eco-system of WinForms/WPF/Silverlight it's pretty easy to transition code if you keep it clean.

There are many graphics APIs for Windows. Which one is best for you depends entirely on what kind of application you are building, which you have not told us.

I would not worry about Microsoft deprecating an API in "6-8 months". Microsoft has been extraordinarily diligent in maintaining old APIs; I know of new desktop application development being done in WinForms, and 20-year old 16-bit MFC applications that are still being used.

If you are building an application now, choose the best API now. Do not worry about what will happen in 6-8 months, because by then there will be another new API coming. Waiting for the ultimate API means you will never start.

I don't want to sound like a live-free-or-die-hard FOSS fanboy (even though I am), but, you could always use an open toolkit like Qt or GTK. They're ubiquitous, and especially in Qt's case, totally customisable in terms of look & feel. Microsoft can't perform any cathedral-style deprecation (cannibalization) to these toolkits.

Qt all the way for windows app

My suggestion would be to use Silverlight :

1.Single codebase between Mac & Windows

2.Out of browser support

3.Rich UI capabilities http://www.silverlight.net/showcase

Seeismic Desktop 2 is a good example .
