  • Metrics API/SDK support is in an experimental state and is not recommended for production use. All metric APIs have been marked with the Obsolete attribute. See #1501 for more information. (#1611)
  • Modified SimpleExportProcessor and BatchExportProcessor to abstract classes; Added SimpleActivityExportProcessor, SimpleLogRecordExportProcessor, BatchActivityExportProcessor, BatchLogRecordExportProcessor; Added the check for Activity.Recorded in SimpleActivityExportProcessor and BatchActivityExportProcessor (#1622)
  • Added check in ActivitySourceAdapter class for root activity if traceid is overridden by calling SetParentId (#1355)

1.0.0-rc1.1

Released 2020-Nov-17

  • Removed GetResource and SetResource Activity extension methods. Added GetResource extension method on BaseProvider (#1463)
  • Added ParentProvider property on BaseProcessor and BaseExporter classes. (#1463)
  • Resource is no longer added to observed Activity objects as a CustomProperty. (#1463)

  • ActivitySourceAdapter supports setting ActivitySource for Activities created without ActivitySource. (#1515)
  • Implemented Shutdown for TracerProvider. (#1489)
  • Resources.CreateServiceResource has been removed in favor of the ResourceBuilder API. (#1533)
  • TracerProviderBuilder.SetResource has been changed to TracerProviderBuilder.SetResourceBuilder. (#1533)
  • By default TracerProvider will set a Resource containing Telemetry SDK details (#1533):
    • telemetry.sdk.name = opentelemetry
    • telemetry.sdk.language = dotnet
    • telemetry.sdk.version = [SDK version]
  • Resource constructor marked as internal, as ResourceBuilder is the recommended API to build resources. (#1566)
  • Changed BaseExportProcessor to have it override OnExport instead of OnEnd; Added check for ActivityTraceFlags to BaseExportProcessor OnEnd (#1574)
