Event Sources, Counters and Listeners, Oh My!

Overview

This is a quick overview of how to add EventSource and EventCounter tracing to an ASP.NET library.

Prerequisites

You should have a basic understanding of EventSource and how to write events. See https://blogs.msdn.microsoft.com/vancem/2012/07/09/introduction-tutorial-logging-etw-events-in-c-system-diagnostics-tracing-eventsource/ for some guidance.

// Treat Client Proxies kinda like Formatters; Hub<T> just tries to get an IClientProxyFactory<T> from DI and invokes it.
// We provide one for `dynamic` and another that can be registered as an open-generic and generated code at runtime.
// Users can provide custom implementations for anything.

public interface IClientProxy {
    Task InvokeAsync(string method, params object[] args);
}

public interface IClientProxyFactory<T> {
    T CreateProxy(IClientProxy proxy); // <-- may need some caching logic
