F#
F# is the functional sibling of C# on .NET. v9.0 (2025) brings Nullable Reference Types integration and better performance for list comprehensions.
When to Use
- Financial Tech: Correctness and domain modeling.
- Data Processing: Pipeline operator
|>and immutability by default. - Interpro: Seamlessly use any NuGet package.
Core Concepts
Discriminated Unions
type Shape = Circle of float | Rect of float * float.
Pipe Operator
data |> filter |> map.
Computation Expressions
async { ... }, task { ... }.
Best Practices (2025)
Do:
- Use Records: Immutable data containers.
- Use Pattern Matching:
match x with .... - Use
SAFE Stack: For full-stack F# web apps (Saturn, Azure, Fable, Elmish).
Don't:
- Don't mimic C#: Avoid classes/inheritance unless interoperating.
