These days I am interested in learning F#, and would like to use it for GUI applications. Unfortunately I have no previous background in .Net or C#. Are there any good resources (web sites, books) for learning this without going through C# first?
Many thanks in advance.
The Real-world Functional Programming book that I wrote with Jon Skeet (sorry for the advertisement!) expects some existing knowledge of object-oriented languages (e.g. C#) but it briefly explains all more advanced features that C# has compared to, for example, Java.
It has a few examples of GUI programming using WinForms (a more modern framework would be WPF, but some concepts are essentially the same). You can take a look at a few examples, because there is some free content related to GUI:
As far as I know, Robert Pickering’s Beginning F# also has some user interface examples and it also includes some WPF examples (although I don’t have the book yet, so I don’t know what exactly does it contain).
However, none of the F# books will make you GUI Expert. You’ll still need to spend some time learning about WinForms/Silverlight/WPF in more details. There are plenty of examples in C# on the internet and after reading one of the above, you should be able to translate them directly to F#, but buying a technology-specific book may be a good idea too.
