Our journey to F#: JSON serialization with a mix of C# and F#

O

There are many libraries for JSON serialization in the .Net realm. The best known are probably Newtonsoft’s Json.NET and System.Text.Json. Both can’t handle F# discriminated unions very well. There are also a couple of F# JSON libraries available like Thoth.Json or FSharp.Json. They are all great libraries, and choosing one is about making trade-offs. However, our case is a bit complicated because we have a mix of C# and F# code. This results in object/value graphs that consist of a...

A little while ago, I asked on Twitter whether someone would be interested in reading about how we generate types from our .Net backend to be used in our TypeScript client. So, here we are. I’ll cover the following topics: Why do we even bother?Generating TypeScript constants from .Net constantsFinding the types used in communication between the .Net backend and the TypeScript clientGenerating TypeScript classes from .Net typesGenerating Angular Services from .Net WebApi...

C# vs. F#

I dared to ask two questions on twitter:

What makes your daily developer life easier in F# compared to C#?What is better in C# than F#?

This post summarizes the answers and my own opinion on where C# and F# shine.
