And here it is!!! My new programming language Osprey! This has been a 20 year long dream, finally made possible with AI assistance. So stoked this is finally possible! 🎉

Stars and shares appreciated! ✨
I want to build a community around this

Have you tried this C# REST library yet?

Some people feel uncomfortable using end to end encrypted chat

That’s like being uncomfortable not broadcasting your conversations to everyone at Microsoft, Apple or Google

Privacy should be the default. It’s not shady to demand privacy

Christian Findlay @cfdevelop.bsky.social · 4d

I can’t believe how entrenched people’s coding style gets

They’re often 10 years out of date and refuse to learn new approaches

I don’t get it. I use multiple languages and pick up every bit of syntax sugar I can

Christian Findlay @cfdevelop.bsky.social · 4d

The most common criticism I hear of generative AI is “it’s not original! It just recombines stuff it already knows!”

Well, that exactly what all human expression is

You think it’s divinely inspired or something?

Christian Findlay @cfdevelop.bsky.social · 5d

If you’re building an agent, you definitely need to add MCP support, and RC Net can bridge the gap between your agent and whatever API you want to talk to

Well, there is an MCP server generator…

It can convert an OpenAPI spec to an MCP server

Yeah. Dart devs went through the roller coaster and came out the other side better off

C# devs haven’t been forced so they continue to sit in their own shit and make up excuses not to do things the easy way

RestClient .Net 7 is huge!

Please help me spread the word

RestClient.Net 7: Compile-Time Safety and OpenAPI MCP Generation

Generate an MCP server in .NET from an OpenAPI (Swagger) YAML/JSON document and use exhaustiveness checks on pattern matching in C# with RestClient.Net 7

Turning on Nullable Reference Type analyzer rules in C# is a no brainer. All codebases should have it

But how do you explain to people who haven’t used null safety that it’s necessary?

Why do they think null checking everything is ok?

Generate a full .NET based MCP server from an OpenAPI 3.x spec with RestClient .Net 7!!!

Windsurf is hitting a Nucliadb MCP server generated from OpenAPI 3.1 YAML

github.com/MelbourneDev...

Christian Findlay @cfdevelop.bsky.social · 8d

RestClient .Net 7 comes with a Nucliadb SDK client generated from the OpenAPI 3.1 YAML. MCP also on the way!

Tests are running in the pipeline against the live NucliaDB server

github.com/MelbourneDev...

Christian Findlay @cfdevelop.bsky.social · 8d

That would be great. Keen to hear how it goes. If you have issues, let me know

Christian Findlay @cfdevelop.bsky.social · 9d

Btw, if you use Exhaustion with Dunet, it should enforce exhaustiveness checks on switches

Christian Findlay @cfdevelop.bsky.social · 9d

If you look at the generated JSON a placeholder example, you can see that it generates similar discriminated unions like Dunet

Christian Findlay @cfdevelop.bsky.social · 9d

Ah right! That gives me a great idea. Dunet looks like it’s just adding the type aliases for closed type hierarchies. This is the gap that needs to be filled for my library Outcome, which has result types for rc net. Will build the same thing. Rc net’s code generator already has this btw

Christian Findlay @cfdevelop.bsky.social · 10d

Can you believe this switch expression is exhaustive? Finally!

I got sick of waiting for unions in C# and just made the damn analyzer myself

You no longer have to go to GitHub repos and beg people for functionality.

Just build it

Want to try exhaustive pattern matching in C# on closed type hierarchies? Yes, it works!!!

AI skeptics are on another level of cognitive dissonance

How can they sit there and doubt it when people are building compilers, industrial strength frameworks and apps from nothing?

Like, what does it take for these people to see reality?

Christian Findlay @cfdevelop.bsky.social · 11d

Every new model is a slight improvement, but most LLMs have a very good grasp of FP

Check out what I’ve achieved here

Ospreylang.dev

Christian Findlay @cfdevelop.bsky.social · 11d

Your team can choose any language that LLMs are trained in. Haskell, Scala, to a lesser extent F# and Ocaml- these are all languages that LLMs are trained with

Your team doesn’t need to stick to bloated OOP languages with no type inference, exhaustiveness checking or type design

RestClient .Net 7 is live!!!

nuget.org/packages/Res...

Try it out!

RestClient.Net 7.0.0

The safest way to make REST calls in C#. Functional HTTP client library with Result types, exhaustiveness checking, and zero exceptions.

nuget.org

Christian Findlay @cfdevelop.bsky.social · 16d

Exhaustive type checks on pattern matching for closed type hierarchies in C#? Sure, why not?

Christian Findlay @cfdevelop.bsky.social · 20d

RestClient .Net 6 has a perfect mutation testing score with
Stryker Mutator

Christian Findlay @cfdevelop.bsky.social · 22d

Just figured out the final design for RestClient .NET 6.

I think this the safest .NET rest client by far.

Narrows HTTP call responses down to success or failure only.

But more importantly an extra analyzer adds exhaustiveness checking on switch. So you CANNOT mess up

Christian Findlay @cfdevelop.bsky.social · 22d

Switzerland may be on the right track. Independence is proving to be a winner here.
