WPF or Windows Forms
I've been playing around with C# console applications for about a year and I want to move on to creating GUI applications. I have never done any GUI development besides basic Java applications, but I want to continue using C#. Should I start learning Windows Forms or jump straight to WPF? Is there a huge difference? Does WPF build on top of Windows Forms or are they totally different?
If you're just starting out, jump straight into WPF.
It will allow you to get starting making rich interfaces using mark-up to define your interface without teaching you the possible bad habits (for WPF) that you'd learn from Windows Forms.
These two are totally different technologies. They do offer some interoperability layers to both directions, but other than that have nothing in common. Windows Forms is more or less a lightweight wrapper on top of Win32/MFC, which means its extensibility in .NET is not that good in all cases. WPF is a new UI framework implemented from scratch. WPF is also much more flexible when it comes to customizing the existing types.
However, at least from my experience, Windows Forms seems to be the more commonly-used desktop UI framework in the industry. Windows Forms can't be used with web development though while WPF offers Silverlight and XBAP applications.
If you have done any UI development before, I'd dare say Windows Forms is easier to learn as it follows more traditional programming paradigms. The programming model of WPF is quite different to this. While WPF can be used in the same way as Windows Forms, most of its benefits are not achieved until you embrace the data binding and encapsulation WPF provides.
Despite stating some points in favor of Windows Forms choosing WPF over Windows Forms would be a no-brainer for me if all you want to do is learn a UI framework. It's superior to Windows Forms in all aspects. I just wish the software industry in general would adapt it on a larger scale! (Though not like anyone writes desktop applications any more since we got the web.)
Both technologies have their pro's and con's.
WPF is better for cross platform development and creating 'flashy' GUI's. However it requires a newer .net framework than WinForms and requires a dx9 compatible GPU or higher (which most people will have).
But it is a little bit more involved to create the interface / wire up all the events etc.
WinForms is still a powerful technology which can often be developed at a faster pace than WPF however, in the end, both technologies can be used to achieve the same thing. However WPF is the 'newer' standard.
WinForms is commonly used to develop business applications whereas WPF is often used to create more end-user based bits of software, apps etc.
