OpenTelemetryExtension.Configuration 2.1.0

v2.1.0

Released: 2026-06-12

Added

• net8.0 target framework. The library now ships netstandard2.0, net8.0
  and net10.0 assets. .NET 8 (LTS) consumers previously resolved the
  netstandard2.0 asset, which excludes ASP.NET Core instrumentation and the
  ExcludedPaths request filter; they now get full feature parity with
  net10.0. .NET 9 apps resolve the net8.0 asset.

OpenTelemetryExtension.Configuration 2.0.1

v2.0.1

Released: 2026-06-12

Changed

• Updated OpenTelemetry.Exporter.OpenTelemetryProtocol and
  OpenTelemetry.Extensions.Hosting to 1.16.0.

Fixed

• OTLP signal URLs no longer contain a double slash when the endpoint has no
  path: http://localhost:4318 now exports to http://localhost:4318/v1/traces
  instead of http://localhost:4318//v1/traces.
• The service.version resource attribute now reports the host application's
  version (entry assembly) instead of the library's own version.
• AddTelemetry(Action<TelemetryOptions>) now throws the documented
  ArgumentNullException instead of a NullReferenceException when the
  configure delegate is null.

OpenTelemetryExtension.Configuration 2.0.0

v2.0.0

Released: 2026-06-10

Added

• AdditionalTracingSources — extra ActivitySource names to collect traces from, registered via AddSource. Enables source-based instrumentation (e.g. Npgsql, MySqlConnector, your own app sources) purely from appsettings.json — no code required.
• AdditionalMeters — extra Meter names to collect metrics from, registered via AddMeter.
• Custom configuration section — the AddTelemetry(IConfiguration) overloads accept an optional sectionName parameter to bind a section other than the default "Telemetry".

Changed

• Enabled now defaults to true — telemetry is on out of the box; set "Enabled": false to turn it off.
• The netstandard2.0 build no longer pulls in ASP.NET Core dependencies — OpenTelemetry.Instrumentation.AspNetCore is only referenced by the net10.0 target, so WPF and console consumers stay lean.
• The local OpenObserve backend setups (Helm chart, Docker Compose) ship with a fixed Basic Auth header so the README examples work copy-paste.
• Updated all NuGet dependencies to their latest versions.

Removed

• EnableSqlClientInstrumentation and the built-in OpenTelemetry.Instrumentation.SqlClient dependency. Database instrumentation is driver-specific and is now added via the ConfigureTracing hook (e.g. AddSqlClientInstrumentation(), AddEntityFrameworkCoreInstrumentation()) or, for drivers with a built-in ActivitySource, via AdditionalTracingSources — see the README's Databases section for migration examples.

OpenTelemetryExtension.Configuration 1.1.1

v1.1.1

Maintenance release — documentation, infrastructure and tooling only. No changes
to the library code or public API.

Documentation

• README restructured for clarity — full configuration reference and external
  links moved to the end, backend docs trimmed to Aspire, Jaeger and OpenObserve.
• Added an explanation of the Configure* hooks, Meters and Sources, with
  examples and links to the OpenTelemetry and Microsoft docs.
• Added "Running Locally with a Backend" guide (start script → launch profile → UI)
  and backend UI preview images.

Infrastructure

• Added .NET Aspire Dashboard setup for both Docker Compose and Helm (with
  NodePort services), and registered the infrastructure files in the solution.

Tooling

• Replaced the release command with an auto-release skill (helper scripts and
  a release-notes template).
• Added an end-to-end telemetry smoke-test (Helm + OpenObserve) that verifies
  exported data actually arrives via the OpenObserve query API.

OpenTelemetryExtension.Configuration 1.1.0

v1.1.0

New Features

• SampleRatio — configure trace sampling via appsettings.json (1.0 = all, 0.1 = 10%). Uses ParentBased(TraceIdRatioBased) sampler.
• ResourceAttributes — add arbitrary OpenTelemetry resource attributes (e.g. team, region) via appsettings.json.
• ExcludedPaths — replaces ExcludeHealthChecks. Accepts a list of paths to exclude from tracing (default: ["/health"]).
• IncludeScopes — controls whether log scopes are included in exported log records (default: true).
• IncludeFormattedMessage — controls whether the formatted log message is included in exported log records (default: true).

Changes

• EnableSqlClientInstrumentation default changed from true to false — opt-in, as not all applications use SQL.
• ExcludeHealthChecks removed — replaced by the more flexible ExcludedPaths.

Improvements

• README rewritten for clarity — cleaner getting started, expanded backend examples.
• TreatWarningsAsErrors enabled across all projects.
• CI now also runs on pull requests.
• GitHub Actions: replaced deprecated actions/create-release@v1 with softprops/action-gh-release@v2.
• RepositoryType, PackageReleaseNotes and dynamic copyright added to NuGet package metadata.
