Microsoft.FeatureManagement Updates

The packages associated with this release are

• Microsoft.FeatureManagement 4.0.0-preview4
• Microsoft.FeatureManagement.AspNetCore 4.0.0-preview4
• Microsoft.FeatureManagement.Telemetry.ApplicationInsights 4.0.0-preview4

Microsoft.FeatureManagement

Enhancements

• The feature flag telemetry pipeline is now integrated with .NET Acitivity instrumentation. Feature manager now has an AcitvitySource called "Microsoft.FeatureManagement". If telemetry is enabled for a feature flag, whenever the feature flag is evaluated, feature manager will start an Activity and add an ActivityEvent with tags containing feature evaluation information. #​455

Breaking Changes

• If you were using earlier preview versions of this package and configuration files to define variant feature flags, they are no longer supported in the .NET Feature Management schema. Instead, please use the Microsoft Feature Management schema to define variant feature flags. #​421.

• AddTelemetryPublisher API and ITelemetryPublisher interface were removed. The feature flag telemetry pipeline is now integrated with .NET Acitivity instrumentation. #​455

Microsoft.FeatureManagement.AspNetCore

• Updated Microsoft.FeatureManagement reference to 4.0.0-preview4.

Microsoft.FeatureManagement.Telemetry.ApplicationInsights

• Updated Microsoft.FeatureManagement reference to 4.0.0-preview4.

Enhancements

• Introduced a new API AddApplicationInsightsTelemetryPublisher to register a feature flag telemetry publisher for Application Insights. #​455

  builder.Services.AddFeatureManagement()
                  .WithTargeting()
                  .AddApplicationInsightsTelemetryPublisher();

Breaking Changes

• The TargetingTelemetryInitializer type has been moved to this package from the now-deprecated Microsoft.FeatureManagement.Telemetry.ApplicationInsights.AspNetCore package. This change simplifies the utilization of feature flag telemetry.

• The type ApplicationInsightsTelemetryPublisher has been removed as its functionality has been replaced with the new API AddApplicationInsightsTelemetryPublisher for publishing feature flag telemetry to Application Insights. #​455

Microsoft.FeatureManagement

Enhancements

• Added support for variant feature flags defined using Microsoft Feature Management schema. Variants and telemetry can be declared using Microsoft Feature Flag schema v2. The Microsoft Feature Management schema is designed to be language agnostic, enabling you to apply a consistent feature management configuration across Microsoft feature management libraries of different programming languages.

Microsoft.FeatureManagement.AspNetCore

• Updated Microsoft.FeatureManagement reference to 4.0.0-preview3.

Microsoft.FeatureManagement.Telemetry.ApplicationInsights

Breaking Changes

• Updated the namespace for ApplicationInsightsTelemetryPublisher to Microsoft.FeatureManagement.Telemetry. In the future, developers using any of our offered telemetry publishers will no longer need to specify the service specific namespaces like using Microsoft.FeatureManagement.Telemetry.ApplicationInsights.

• Updated the namespace for TrackEvent extension method of TelemetryClient to Microsoft.ApplicationInsights. The previous directive using Microsoft.FeatureManagement.Telemetry.ApplicationInsights is no longer required when calling the TrackEvent method.

Microsoft.FeatureManagement.Telemetry.ApplicationInsights.AspNetCore

• Updated Microsoft.FeatureManagement reference to 4.0.0-preview3.

v4.0.0-preview2

Microsoft.FeatureManagement Updates

The packages associated with this release are

• Microsoft.FeatureManagement 4.0.0-preview2
• Microsoft.FeatureManagement.AspNetCore 4.0.0-preview2
• Microsoft.FeatureManagement.Telemetry.ApplicationInsights 4.0.0-preview2
• Microsoft.FeatureManagement.Telemetry.ApplicationInsights.AspNetCore 4.0.0-preview2

Microsoft.FeatureManagement

Enhancements

• Added support for variant feature flag-based service provider in dependency injection. It allows different service implementations to be injected automatically for different targeted audiences based on their variant assignment. (#​39). See more details here.
• Added a TargetingContext property to the EvaluationEvent. This allows feature evaluation events to accurately represent what the targeting context was at the time of feature evaluation. (#​409)

Microsoft.FeatureManagement.AspNetCore

Enhancements

• Introduced a new ASP.NET Core middleware called TargetingHttpContextMiddleware. It makes targeting information available from HttpContext on each request. (#​409)
• Added support for .NET 8 target framework. (#​364)

Microsoft.FeatureManagement.Telemetry.ApplicationInsights

Enhancements

• Added a TargetingId property to the feature evaluation events sent to Application Insights. The TargetingId is the identifier of a targeted user during feature evaluation. This new property allows you to correlate feature evaluation events with other telemetry data your application sends to Application Insights, as long as they share the same TargetingId. (#​409)

Microsoft.FeatureManagement.Telemetry.ApplicationInsights.AspNetCore

Enhancements

• Introduced a telemetry initializer named TargetingTelemetryInitializer. It automatically adds targeting information to telemetry data your application sends to Application Insights. This can be used to correlate your telemetry data with feature evaluation events based on the targeting information during your telemetry analysis. (#​409)
