Version 2.4.0-beta3

Version 2.4.0-beta2

• BASE: Removed metric aggregation functionality as there is not enough feedback on the API surface yet.

Version 2.4.0-beta1

• BASE: Event telemetry is set to be sampled separately from all other telemetry types. It potentially can double the bill. The reason for this change is that Events are mostly used for usage analysis and should not be subject to sampling on high load of requests and dependencies. Edit ApplicationInsights.config file to revert to the previous behavior.
• BASE: Added dependency on System.Diagnostics.DiagnosticsSource package. It is still possible to use standalone Microsoft.ApplicationInsights.dll to track telemetry.
• BASE: StartOperation starts a new System.Diagnostics.Activity and stores operation context in it. StartOperation overwrites OperationTelemetry.Id set before or during telemetry initialization for the dependency correlation purposes.
• BASE: OperationCorrelationTelemetryInitializer initializes telemetry from the Activity.Current. Please refer to https://github.com/dotnet/corefx/blob/master/src/System.Diagnostics.DiagnosticSource/src/ActivityUserGuide.md for more details about Activity and how to use it
• BASE: Request.Success field will not be populated based on ResponseCode. It needs to be set explicitly.

• BASE: Added constructor overloads for TelemetryConfiguration and added creation of a default InMemoryChannel when no channel is specified for a new instance.
  TelemetryClient will no longer create an InMemoryChannel on the configuration instance if TelemetryChannel is null, instead the configuration instances will always have a channel when created.
• BASE: TelemetryConfiguration will no longer dispose of user provided ITelemetryChannel instances. Users must properly dispose of any channel instances which they create, the configuration will only auto-dispose of default channel instances it creates when none are specified by the user.

Version 2.3.0-beta1

• BASE: Added metric aggregation functionality via MetricManager and Metric classes.
• BASE: Exposed a source field on RequestTelemetry. This can be used to store a representation of the component that issued the incoming http request.

• BASE: Context properties NetworkType, ScreenResolution and Language marked as obsolete. Please use custom properties to report network type, screen resolution and language. Values stored in these properties will be send as custom properties.
• BASE: Dependency type was updated to reflect the latest developments in Application Insights Application Map feature. You can set a new field - Target. CommandName was renamed to Data for consistency with the Application Analytics schema. DependencyKind will never be send any more and will not be set to "Other" by default. Also there are two more constructors for DependencyTelemetry item.
• BASE: Type SessionStateTelemetry was marked obsolete. Use IsFirst flag in SessionContext to indicate that the session is just started.
• BASE: Type PerformanceCounterTelemetry was marked obsolete. Use MetricTelemetry instead.
• BASE: Marked RequestTelemetry.HttpMethod as obsolete. Put http verb as part of the name for the better grouping by name and use custom properties to report http verb as a dimension.

• BASE: Richpayload event source event is generated for all framework versions of SDK (before it was supported in 4.6 only)
• BASE: TelemetryClient has a new method TrackAvailability. Data posted using this method would be available in AppAnalitics only, Azure portal UI is not available at this moment.

Version 2.2.0-beta1

• BASE: Add ExceptionTelemetry.Message property. If it is provided it is used instead of Exception.Message property for the outer-most exception.
• BASE: Telemetry types can be excluded from sampling by specifing ExcludedTypes property.
• BASE: ServerTelemetryChannel: changed backoff logic to be less aggressive, added diagnostics event when backoff logic kicks in and added more tracing. (Done to address issues when data stops flowing till application gets restarted)

Version 2.1.0-beta4

• BASE: Bug fix

Version 2.1.0-beta3

• BASE: Support partial success (206) from the Application Insights backend. Before this change SDK may have lost data because some items of the batch were accepted and some items of the batch were asked to be retried (because of burst throttling or intermittent issues).

Version 2.0.0

• BASE: Disallow Nan, +-Infinity measurements. Value will be replaced on 0.
• BASE: Disallow Nan, +-Infinity metrics (Value, Min, Max and StandardDeviation). Values will be replaced on 0.

Version 2.0.0-rc1

• BASE: Writing telemetry items to debug output can be disabled with IsTracingDisabled property on TelemetryDebugWriter.
  Telemetry items that were filtered out by sampling are now indicated in debug output. Custom telemetry processors can now invoke
  method WriteTelemetry on TelemetryDebugWriter with filteredBy parameter to indicate in debug output that an
  item is being filtered out.
• BASE: DependencyTelemetry.Async property was removed.
• BASE: DependencyTelemetry.Count property was removed.
• BASE: When configuration is loaded from ApplicationInsights.config incorrect and broken elements are skipped. That includes both high level elements like TelemetryInitializers as well as individual properties.

• BASE: Cut Phone and Store support
• BASE: Updated DependencyTelemetry to have new properties ResultCode and Id
• BASE: If ServerTelemetryChannel is initialized programmatically it is required to call ServerTelemetryChannel.Initialize() method. Otherwise persistent storage will not be initialized (that means that if telemetry cannot be sent because of temporary connectivity issues it will be dropped).
• BASE: ServerTelemetryChannel has new property StorageFolder that can be set either through code or though configuration. If this property is set ApplicationInsights uses provided location to store telemetry that was not sent because of temporary connectivity issues. If property is not set or provided folder is inaccessible ApplicationInsights will try to use LocalAppData or Temp as it was done before.
• BASE: TelemetryConfiguration.GetTelemetryProcessorChainBuilder extension method is removed. Instead of this method use TelemetryConfiguration.TelemetryProcessorChainBuilder instance method.

Version 0.17

• BASE: Application Insights now distributes separate binaries for framework 4.0 and 4.5. Library for the framework 4.5 will not require EventSource and BCL nuget dependencies. You need to ensure you refer the correct library in packages.config. It should be <package id="Microsoft.ApplicationInsights" version="0.17.*" targetFramework="net45" />
• BASE: Diagnostics telemetry module is not registered in ApplicationInsights.config and no self-diagnostics messages will be sent to portal for non-web applications. Insert <Add Type="Microsoft.ApplicationInsights.Extensibility.Implementation.Tracing.DiagnosticsTelemetryModule, Microsoft.ApplicationInsights" /> to <TelemetryModules> node to get SDK self-diagnostics messages from your application.
• BASE: ApplicationInsights.config file search order was changed. File from the bin/ folder will no longer be used even if exists for the web applications.

Version 0.15

• BASE: New property Operation.SyntheticSource now available on TelemetryContext. Now you can mark your telemetry items as �not a real user traffic� and specify how this traffic was generated. As an example by setting this property you can distinguish traffic from your test automation from load test traffic.

Version 2.4.1

• WEB: Hotfix to address the issue where DependencyCollection breaks Azure Storage Emulator calls

Version 2.4.0

• WEB: Updated version of DiagnosticSource to 4.4.0

Version 2.4.0-beta5

• WEB: Updated version of DiagnosticSource referenced.

Version 2.4.0-beta4

• WEB: Bug fixes.

Version 2.4.0-beta3

• WEB: Exceptions statistics feature is not enabled by default
• WEB: Parse AppId from HTTP response headers when dependency collection is facilitated with Http Desktop DiagnosticSource
• WEB: Fix double correlation header injection with latest DiagnosticSource
• WEB: DisableDiagnosticSourceInstrumentation configuration flag was added to DependencyTrackingTelemetryModule.
  • By default DisableDiagnosticSourceInstrumentation is set to false, this enables correlation of telemetry items and application map in multi-tier applications.
  • When DisableDiagnosticSourceInstrumentation is set to true (so that the instrumentation is off)
    • correlation between requests, dependencies, and other telemetry items is limited,
    • telemetry correlation between multiple services involved in the operation processing is not possible,
    • and the cross-component correlation feature and application map experience is limited.
  • Note: this configuration option has no effect for applications that run in an Azure Web Application with the ApplicationInsights site extension or have runtime instrumentation.
• WEB: Fix memory leak in Dependency collector

Version 2.4.0-beta2

• WEB: Handle breaking changes from DiagnosticSource
• WEB: Exceptions statistics metrics uses .Context.Operation.Name instead of custom property operationName
• WEB: Separate event source names for Web and Dependency Modules to fix the bug
• WEB: Fix DependencyCollector memory leak on netcoreapp1.1 and prior

Version 2.4.0-beta1

• WEB: Report status code for the dependencies failed with non-protocol issue like DNS resolution or SSL shakeup problems.
• WEB: Implemented automatic telemetry correlation: all telemetry reported within the scope of the request is correlated to RequestTelemetry reported for the request.
• WEB: Implemented Correlation HTTP protocol: default headers to pass Operation Root Id and Parent Id were changed. This version is backward compatible with previously supported headers.
• WEB: Implemented injection into the HTTP stack for .NET 4.6 to leverage DiagnosticSource to gain access to the WebRequest and WebResponse objects for header injections, without the need of using the profiler.
• WEB: Dependency to System.Diagnostics.DiagnosticsSource package is added for Web SDK on .NET 4.5.
• WEB: Improvements to exception statistics, e.
