* Added Azure Container Apps resource detector.
([#41803](https://github.com/Azure/azure-sdk-for-net/pull/41803))
+* Added `Azure.Monitor.OpenTelemetry.LiveMetrics`, enabling the sending of [live
+ metrics
+ data](https://learn.microsoft.com/azure/azure-monitor/app/live-stream).
+ The newly added `EnableLiveMetrics` property is set to `true` by default. This
+ property can be set to `false` to disable live metrics.
