What I mean is writing a desktop application without falling back to using C# for all the front-end code and relegating F# to being a glorified DSL for data processing. Microsoft doesn't believe anyone wants to make apps in F#; Visual Studio doesn't even come with templates for it. You're expected to use F# to write libraries like Fsharp.Data, and write your app code in C#. If I wanted to code in C#, I'd code in C#, but I don't.

A desktop app on Windows either uses WPF or WinForms. In either case F# doesn't stop at all. In fact I would say that building WPF desktop on F# is more intuitive than C#.

    I have written thousands of pages of example applications in articles for the F# Journal.

There are some decent samples on MSDN, 56 in F# at the time of writing. Most aren't GUI apps, but some are. https://code.msdn.microsoft.com/site/search?f%5B0%5D.Type=ProgrammingLanguage&f%5B0%5D.Value=F%23&f%5B0%5D.Text=F%23&sortBy=Date https://code.msdn.microsoft.com/site/search?f%5B0%5D.Type=Pr... My "WPF Image Cropper" sample might be interesting to you - pure F# WPF via XAML type provider. I am not a GUI dev, though, so it's probably crap design :)
