Release 0.4.0-beta.1

[pellared]

Added

• Add WCF traces instrumentation (server-side for .NET Framework, client-side for both .NET Core and .NET Framework).
• Support ASP.NET Core OpenTelemetry Log exporter related environment variables:
  • OTEL_LOGS_EXPORTER,
  • OTEL_DOTNET_AUTO_LOGS_CONSOLE_EXPORTER_ENABLED,
  • OTEL_DOTNET_AUTO_LOGS_ENABLED_INSTRUMENTATIONS,
  • OTEL_DOTNET_AUTO_LOGS_DISABLED_INSTRUMENTATIONS,
  • OTEL_DOTNET_AUTO_LOGS_INCLUDE_FORMATTED_MESSAGE.
• Support OTEL_DOTNET_AUTO_GRAPHQL_SET_DOCUMENT (default value: false) environment variable which controls whether graphql.document attribute is set.
• Add ILogger logging instrumentation for .NET Core 3.1+.
• Add telemetry resource attributes.
• Add support for the b3 propagator.
• Add MassTransit traces instrumentation.
• Add OpenTelemetry.AutoInstrumentation Nuget package.
• Support for Process metrics collection using the OpenTelemetry.Instrumentation.Process package.

Changed

• Replaced OTEL_DOTNET_AUTO_TRACES_PLUGINS and OTEL_DOTNET_AUTO_METRICS_PLUGINS with new environment variable OTEL_DOTNET_AUTO_PLUGINS.
• Adjusted tags for MongoDB integration. See pull request for more details.
• Extend MySql.Data traces instrumentation for versions 8.0.31+. Versions 8.0.31+ require bytecode instrumentation.

Removed

• Removed support for MongoDB integration for MongoDB.Driver.Core prior to 2.13.3.

Fixed

• Log folder structure is fully created on Linux.
• Update GraphQL instrumentation to follow the OpenTelemetry semantic conventions.
• Fixed the race between requesting ReJIT of methods targeted for bytecode instrumentation and their first execution. The race allowed, in rare occasions, for the first few executions of the method to not be instrumented. See issue #1242.
• Span kind for GraphQL instrumentation is set as span property instead of attribute.
