#327 introduced a method for tracking user interactions

dotnet-sdk/src/OpenFeature/OpenFeatureClient.cs

Lines 305 to 328 in 929fa74

	/// <summary>
	/// Use this method to track user interactions and the application state.
	/// </summary>
	/// <param name="trackingEventName">The name associated with this tracking event</param>
	/// <param name="evaluationContext">The evaluation context used in the evaluation of the flag (optional)</param>
	/// <param name="trackingEventDetails">Data pertinent to the tracking event (Optional)</param>
	/// <exception cref="ArgumentException">When trackingEventName is null or empty</exception>
	public void Track(string trackingEventName, EvaluationContext? evaluationContext = default, TrackingEventDetails? trackingEventDetails = default)
	{
	if (string.IsNullOrWhiteSpace(trackingEventName))
	{
	throw new ArgumentException("Tracking event cannot be null or empty.", nameof(trackingEventName));
	}
	var globalContext = Api.Instance.GetContext();
	var clientContext = this.GetContext();
	var evaluationContextBuilder = EvaluationContext.Builder()
	.Merge(globalContext)
	.Merge(clientContext);
	if (evaluationContext != null) evaluationContextBuilder.Merge(evaluationContext);
	this._providerAccessor.Invoke().Track(trackingEventName, evaluationContextBuilder.Build(), trackingEventDetails);
	}

This method is not currently available on the IFeatureClient abstraction. This means developers or consumers who depend on this abstraction cannot use this method. While Tracking is still experimental, it would be good to ensure we appropriately expose this API.
