Hi There;
I try to impement the power bi solution located there; https://powerbi.microsoft.com/en-us/documentation/powerbi-developer-walkthrough-push-data-register-app-with-azure-ad/ My data resides at the power BI database (or cloud I am not sure about the location). Dataset is created successfully, however, there is a problem in addRowsToDataset function. What am I missing? Thanks in advance.

private static string token = string.Empty;

datasetId = getDatasetId();
createDataset();
addRowsToDataset(datasetId, "CorporationProduct");
Console.ReadKey();
}
catch (Exception ex)

Console.WriteLine("An error occured in main function. ");
Console.WriteLine(ex.Message);
