Cannot convert null literal to non-nullable reference type.

Cannot convert null literal to non-nullable reference type.

Nullability of reference types in type of parameter 'sender' of 'void ApplicationInsightsProvider.TaskScheduler_UnobservedTaskException(object sender, UnobservedTaskExceptionEventArgs e)' doesn't match the target delegate 'EventHandler<UnobservedTaskExceptionEventArgs>' (possibly because of nullability attributes).

Non-nullable field 'client' must contain a non-null value when exiting constructor. Consider declaring the field as nullable.

Dereference of a possibly null reference.

Possible null reference argument for parameter 'exception' in 'Task IInsights.TrackDependencyAsync(string dependencyType, string dependencyName, string data, DateTimeOffset startTime, TimeSpan duration, bool success, int resultCode = 0, Exception exception = null)'.

Dereference of a possibly null reference.

Possible null reference return.

Possible null reference argument for parameter 'value' in 'void Dictionary<string, string>.Add(string key, string value)'.
