TrackEvent overloaded function not available

[codelegger]

I am updating my app from win8.1 to uwp and i am using this function from
Namespace: Microsoft.ApplicationInsights
void TrackEvent(
String^ eventName,
IDictionary<String^, String^>^ properties = null,
IDictionary<String^, double>^ metrics = null
)

Why this function is not available in ApplicationInsight-cpp or any alternative ??

You can use:
void TrackEvent(const std::wstring& eventName, const wstring_wstring_map& properties, const std::map<std::wstring, double>& measurements);
