If you have any experience in Haskell, you know the IO monad. Some people think it just makes things ugly – but I think it is good, since we are functional programming and we should know when we are using an impure function. What we will do is to define a[...]

F# is a great language, but its support is a bit limited. For example, you can make a WPF project in F# but you cannot use XAML. In this post I will demonstrate how to create a simple calculator using F#, WPF and XAML. I did not compare the efficiency to [...]
