Request tracing in a system involves monitoring and recording the sequence of actions and calls performed during the processing of a specific request. This helps understand how the request passes through various system components, identify bottlenecks and errors.

In C#, this is often implemented using logging, middleware, or specialized libraries that add unique identifiers to requests and gather information about each processing step. For example, in ASP.NET Core, middleware can be used to log the request path:

public class RequestTracingMiddleware
{
    private readonly RequestDelegate _next;

    public RequestTracingMiddleware(RequestDelegate next) => _next = next;

    public async Task InvokeAsync(HttpContext context)
    {
        var requestId = Guid.NewGuid().ToString();
        context.Items["RequestId"] = requestId;
        Console.WriteLine($"Starting request processing {requestId} at {DateTime.Now}");

        await _next(context);

        Console.WriteLine($"Finished request processing {requestId} at {DateTime.Now}");
    }
}

This way, the request path and processing time can be tracked at each stage.
