It almost makes it embarrassing to use FP/immutable styles in C#. I was found myself thinking “the team is going to hate this code,” even though it’s literally how the code must be written.

Rubio is a wasteful diversity move.

Forgot to tag @dzoukr.cz since the post calls out the excellent Dapper.Fsharp library.

That’s cool to hear. It’s nice to know other people are in your shoes; it can feel like you’re on an island sometimes.
Are y’all going to try to cut out the C# eventually or will you keep the 50/50 split?

Nice!
This post does a better job at explaining kind of how we do translations if you are interested. It’s probably too barbaric for your situation though lol.
We rely heavily on Microsoft.FsharLu.JSON which has this compact serialization technique built in.

Cross-Boundary ADTs
Modeling a domain with algebraic data types (ADTs) is a powerful, expressive way to design code that is both concise and readable. Too often, code that does too little with too many lines negatively i...

Yup! It’s the | operator, but you just add a tag (in the screenshot, it’s “state”). As long as the tag is in each type and is a literal value, the TS compiler is smart enough to know what keys are on the object. It goes pretty far for making the domain explicit on the FE.

This basically makes F# the point of truth though, I suppose. The other systems have conventions that give deference to the F# system (which works well in our situation).

Basically what we do there is on deserializing the payload, we do a conversion to whatever the language’s natural ADT type is (discriminated unions in TS, and enums in Swift). Sort of a translation layer that lives at the boundary.
Then F# naturally deserializes to a DU if the JSON structure works

I haven’t followed C# in a little more than a year now, but last I saw it didn’t seem like unions would be very similar to F#.
My gut reaction here would be to do compact serialization of DUs (where tag values are the keys) and deserialize it in C# the same way we do with TS and Swift.

Not sure how valuable a study is that polls people who didn’t vote after a winner was already determined. I’m sure a sociologist or psychologist would know better than me, but it seems obvious there’d be a strong implicit bias to not say you voted for the loser.

I feel like it’s maximum unfortunate any time FAANG gobbles up anything. :(
But it does lift my spirits a bit that you see some possible silver lining.

When I was young we’d drive from Taylorsville to the one in Statesville NC, it was great as a kid because you could always go straight to your favorite food.
