C#

A thin P/Invoke layer over the C ABI, shipped on NuGet with the native library for win-x64, win-arm64, linux-x64, linux-arm64, osx-x64 and osx-arm64.

dotnet add package Wickra.StrategyCi

using System.Text.Json;
using Wickra.StrategyCi;

using var session = new Session();

string response = session.Command(JsonSerializer.Serialize(new
{
    cmd = "run_suite",
    tests,                              // StrategyTest objects
    data = new { BTCUSDT = candles },   // dataset_ref -> candles
}));

var suite = JsonSerializer.Deserialize<JsonElement>(response);
Console.WriteLine($"{suite.GetProperty("passed")} passed");

Session is IDisposable and owns the native handle; Session.Version() is static. The correct native library is resolved per platform from the NuGet payload, and in a dev checkout the resolver also probes the Cargo target tree.

The boundary

Every binding exposes the same two things: a Session, and one call that takes a command envelope as JSON and returns the response as JSON. The commands are run_test, run_suite, bless, list and version, and the response bytes are identical in every language — that is what the golden corpus pins.

Errors in the request — an unknown command, a malformed test — come back in-band as {"ok":false,"error":…}, because they are data about the request rather than a failure of the call.
