3.1.2

Version 3.1.2

• Fix HttpException: Request is not available in this context in the WEB package when calling TrackDependency from Application_Start in classic ASP.NET. The WEB activity processors now safely handle the case where HttpContext.Request is not yet available.
• Fix #​3163: TelemetryConfiguration.CreateDefault() on classic ASP.NET now returns a configuration already populated from ApplicationInsights.config (connection string, sampling, storage, live metrics, request/dependency tracking, etc.). A new PreApplicationStartMethod (WebApplicationInsightsInitializer) materializes and populates the singleton before Application_Start runs, so customer code calling TelemetryConfiguration.CreateDefault() from Global.asax.cs no longer gets an empty configuration. The ApplicationInsightsHttpModule no longer carries the config-reading bookkeeping. TelemetryConfiguration.PrependOpenTelemetryBuilderConfiguration no longer throws if the configuration was already built — it silently skips, so a second TelemetryClient constructed against an already-built configuration no longer throws InvalidOperationException.

3.1.1

Version 3.1.1

• Update OpenTelemetry and Azure Monitor dependencies to address known security advisories (e.g. GHSA-g94r-2vxg-569j in OpenTelemetry.Api 1.15.1): Update OpenTelemetry and Azure Monitor packages to address vulnerabilities microsoft/ApplicationInsights-dotnet#3174
  • OpenTelemetry 1.15.3
  • OpenTelemetry.Exporter.Console 1.15.3
  • OpenTelemetry.Exporter.InMemory 1.15.3
  • OpenTelemetry.Extensions.Hosting 1.15.3
  • OpenTelemetry.Instrumentation.AspNetCore 1.15.2
  • OpenTelemetry.Instrumentation.AspNet 1.15.2

3.1.0

Version 3.1.0

• Make TelemetryContext properties public and propagate them via TelemetryClient.
• Add fallback to APPLICATIONINSIGHTS_CONNECTION_STRING environment variable for Base, Web, and NLog packages when connection string is not set via code.
• Update Azure.Monitor.OpenTelemetry.Exporter to 1.7.0. This includes updated mappings for telemetry context.
• Fix OTEL_SDK_DISABLED not being honored when TelemetryConfiguration.DisableTelemetry is set in DI scenarios., #​3157
• Fix TrackAvailability ignoring user-specified Timestamp on AvailabilityTelemetry. The timestamp is now emitted as microsoft.availability.testTimestamp so downstream exporters can use the correct event time.
• Added netstandard2.0 target framework to Microsoft.ApplicationInsights package to support customers with shared libraries targeting netstandard2.0.
• Fix TelemetryClient.Context.Cloud.RoleName set after construction now applies to all telemetry.
• Fix bug where Debug/Trace level logs from TrackTrace API were not emitted to Application Insights
• Fix Track API calls to not mutate the passed in dictionary if it is readonly
• Fix NullReferenceException in TelemetryClient.Flush() and FlushAsync() when called from DI scenarios
• Fix ApplicationVersion ignored: ApplicationInsightsServiceOptions.ApplicationVersion is now applied as service.version on the OpenTelemetry Resource for both AspNetCore and WorkerService packages
• Fix HttpRequestExtensions.UnvalidatedGetHeader always returning empty string instead of the actual header value. Restored max-length enforcement to guard against oversized header values.

• Update Azure.Monitor.OpenTelemetry.Exporter dependency to 1.6.0

3.0.0-beta2

• Added Self Diagnostics feature
• Updated the default sampler from Fixed Rate to Rate-Limited Sampling.

• Add properties in TelemetryConfiguration to configure underlying exporter

Bug fix

• Fix TrackMetric(MetricTelemetry) unsupported telemetry type error

  • Microsoft.ApplicationInsights
  • Microsoft.ApplicationInsights.AspNetCore
  • Microsoft.ApplicationInsights.WorkerService
  • Microsoft.ApplicationInsights.Web
  • Microsoft.ApplicationInsights.NLogTarget
• Classic APIs of the above packages are preserved; calls are translated to OpenTelemetry telemetry.
• Other packages not listed above (such as certain auto-collectors and logging adapters that were published from this repo previously) will not have future versions published. See BreakingChanges.md for details.

2.23.0

• no changes since beta.

2.23.0-beta1

• Populate required field Message with "n/a" if it is empty
• Fix ITelemetryModule singleton registration to support presence of keyed services
