问题 What are the best practices for building a GUI desktop app that will support both Windows and OS X? Let's say it's budgeting software, so there is a bit of math and some big data structures. User data is saved in XML files; there is no separate database or networking. At one extreme, you could just build the Windows version in C# and the Mac version in Objective C. Is there a better approach, so you can more easily keep the two versions in sync and write less duplicate code? Would you write

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post.

So the task at hand is to find out which framework to use to create the HTML/CSS/JS files to embed in the application. For the development of the HTML/CSS/JavaScript we would be

问题 Is it possible to create Windows desktop applications in JavaScript? I am aware of HTA (HTML Application) programs, but was wondering if there were a newer .NET or other solution where I could make use of the DLL libraries included with Visual Studio. 回答1: Latest .NET version doesn't have such feature, but you've options to do it: a) A WebBrowserObject in a WPF or Windows Forms application (it'll be an embedded Internet Explorer). b) Opera Widgets, which is a Opera browser-based presentation

问题 I need to know is there any way to publish traditional desktop applications to windows store. The link, http://blogs.msdn.com/b/windowsstore/archive/2012/06/08/listing-your-desktop-app-in-the-store.aspx says we cannot upload the desktop app, but we can give a url for the customers to download.
