One question you might ask yourself before starting a bigger project in F# How to inject dependencies? Let me show you how we used partial application to achieve loosely coupled testable components that can be tested in isolation or together in a broader perspective (acceptance tests). I will use Giraffe as the host, but the technique is free from any framework dependencies.

F# is a nice functional alternative in .NET. I have convinced my teammates to use F# in our project at my work in a small new accounting bounded context that would be hosted by .NET Core C# host and Autofac based composition root.

There's a legend around F# that the language is good for science, academic stuff (yes it is good for this as well but not only). Most people think that functional languages are complicated and thus will make them not productive. Nonsense! Let me introduce you to some cool F# features that can make you more productive.

Once I came up with a team-building workshop which you can carry out with your teammates. It focuses on skills being developed during the project duration. It may help with early burnout detection, silent disagreement or simply it may help you with moving forward with some nice techy idea.
