CarpaNet - a .NET ATProtocol Library

CarpaNet is a .NET library for ATProtocol that uses Roslyn source generators to produce type-safe API bindings from Lexicon JSON schema files. It's the replacement for FishyFlip.

Quick Start

Add the CarpaNet NuGet package and declare which lexicons you need:

<ItemGroup>
  <PackageReference Include="CarpaNet" Version="1.*" />
</ItemGroup>

<ItemGroup>
  <LexiconResolve Include="app.bsky.actor.getProfile" />
  <LexiconResolve Include="app.bsky.feed.post" />
  <LexiconResolve Include="com.atproto.repo.createRecord" />
</ItemGroup>

Then use the generated client:

using CarpaNet;

var client = ATProtoClientFactory.Create();

var profile = await client.AppBskyActorGetProfileAsync(
    new AppBsky.Actor.GetProfileParameters { Actor = new ATHandle("alice.bsky.social") });

Console.WriteLine($"{profile.DisplayName} (@{profile.Handle})");
