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)
