Dependencies on .NET Framework

When OpenTelemetry .NET AutoInstrumentation is compiled for .NET Framework, it uses the net462 Target Framework Moniker (TFM). As a result, the ZIP archive deployment contained dependency assemblies targeted for .NET Framework 4.6.2. Some of these assemblies were not designed to be used with later versions of .NET Framework.

Now, when the OpenTelemetry ZIP archive is built, dependency assemblies are included for all supported .NET Framework versions. OpenTelemetry .NET AutoInstrumentation detects the .NET Framework version at install time and runtime, then loads the correct version of dependency assemblies.

Removed

• Dropped support for OTEL_DOTNET_AUTO_SQLCLIENT_SET_DBSTATEMENT_FOR_TEXT and OTEL_DOTNET_AUTO_ENTITYFRAMEWORKCORE_SET_DBSTATEMENT_FOR_TEXT. These features are always enabled. Statements are sanitized.
• Support for macOS Ventura 13 x64. macOS libraries are built and tested against macOS Sonoma 14 arm64.

Fixed

• Fixed deadlock occurring in Assembly Resolver. See #4269
  for details.
• Fixed rule engine check for .NET 9 to reflect longer support for STS channel.
• Fix bug in signal specific OTLP exporter variables: OTEL_EXPORTER_OTLP_TRACES_PROTOCOL, OTEL_EXPORTER_OTLP_METRICS_PROTOCOL and OTEL_EXPORTER_OTLP_LOGS_PROTOCOL. See #4593 for details.
