Instrument .NET applications

When using .NET for Honeycomb, there are several possible approaches.

• Instrument your code using Honeycomb .NET, an open source library that mimicks many of the Honeycomb beelines and sends data directly to Honeycomb

• Instrument your code using OpenTelemetry .NET; you can then export it to Honeycomb with the OpenTelemetry Collector or using an OTLP exporter:

  string apiKey = Environment.GetEnvironmentVariable("HONEYCOMB_API_KEY");
  string dataset = Environment.GetEnvironmentVariable("HONEYCOMB_DATASET");
  
  using var openTelemetry = Sdk.CreateTracerProviderBuilder()
          .addSource("Samples.SampleClient", "Samples.SampleServer")
          .SetResourceBuilder(ResourceBuilder.CreateDefault().AddService("dotnet-otlp"))
          .AddOtlpExporter(opt => {
              opt.Endpoint => new Uri("https://api.honeycomb.io:443");
              opt.Headers  => $"x-honeycomb-team={apiKey},x-honeycomb-dataset=${dataset}";
          })
          .Build();
