+Keyed DI is not available on `netstandard2.0`. Filter the `IEnumerable` by name instead:
+
+```csharp
+var monitors = provider.GetRequiredService>();
+var monitor = monitors.First(m => m.Name == "quote-feed");

+monitor.Degraded += (_, e) => Console.WriteLine($"{e.MonitorName}: degraded");
+monitor.Recovered += (_, e) => Console.WriteLine($"{e.MonitorName}: recovered");

+Alternatively, use `DynamicHealthMonitorManager` which requires no DI at all and is fully supported on `netstandard2.0`.
