Gien is a software developer with 7 years of experience, mainly in a .NET environment.
She is a strong believer of continuously learning by deliberate practice and knowledge sharing, which is why she takes part in the organization of two Belgian communities, namely DDDBE and SoCraTesBE.
Like many companies, our main code base is a C# monolith. Although there is a lot of domain knowledge captured in it, using C# wasn't always the best choice to solve our domain problems. When we discovered F#, we realised that it was a better fit for some of the features we were currently implementing in C#. However, rewriting everything at once in F# would be ineffective. The manual says C# and F# play nice together. So we tried that out, pushing it as far as we could.
In this talk I will show you how we used F# in our existing C# monolith. I will talk about the positive and negative effects of our decisions, what I would do differently in the future and whether or not C# and F# do indeed play nice together.
