This sample is the .NET implementation of the official Azure Voting App. This sample creates a multi-container application in a Kubernetes cluster like the original one.

The application interface is built using ASP.NET Core Blazor Server. The data component uses Redis.

This sample also includes the following features:

1. Instrumented to produce OpenTelemetry traces and export the traces to the console.
2. Request to GET /traced-exception endpoint will throw an exception. It shows how unhandled exceptions are logged in the active OpenTelemtry span.
3. Instrumented to emit built-in .NET metrics and custom metrics with prometheus-net. The metrics are available on the /metrics endpoint in the OpenMetrics format.
4. Deployment with Helm, Kubernetes manifest, or Docker compose.
