OnnxRuntimeSharp

Low-level ONNX Runtime C API interop in modern C#. Cross-platform, trimmable, and AOT/NativeAOT compatible.

Example

The application supplies the native ONNX Runtime runtime package and owns the managed input and output buffers. Tensors pin those buffers once, so steady state inference does not allocate managed memory.

using OnnxRuntimeSharp;

using var environment = new OrtEnvironment();
using var session = new OrtSession(environment, File.ReadAllBytes("mnist-8.onnx"));
using var input = new OrtTensor<float>(new float[28 * 28], [1, 1, 28, 28]);
using var output = new OrtTensor<float>(new float[10], [1, 10]);

session.Run(input, output);

Profiling

Enable profiling before creating the session, run inference, and finish the profile to retrieve the trace file path.

using var options = new OrtSessionOptions();
options.EnableProfiling("mnist-profile");
using var session = new OrtSession(environment, model, options);
// Run inference.
var profilePath = session.EndProfiling();

The OnnxRuntimeSharp.Profiler project runs the bundled mnist-8.onnx model and emits an ONNX Runtime JSON trace.

Building
