Hi everyone,

 

I'm trying to get the access to the tables inside a dataset. I managed to get access to the dataset however the when I use dataset.Tables it always returns null. I also tried to use Datasets.GetTables and passed my dataset ID however it returned "Operation returned an invalid status code 'NotFound'" while with the same Dataset ID, I can get the dataset successfully. I'm using Microsoft.PowerBI.Api.V2 and developing on a Windows App. Can someone help to point out what I am missing here please? Below is my code

 

var credential = new UserPasswordCredential(Username, Password);

// Authenticate using created credentials
var authenticationContext = new AuthenticationContext(AuthorityUrl);
var authenticationResult = authenticationContext.AcquireTokenAsync(ResourceUrl, ClientId, credential).Result;

var tokenCredentials = new TokenCredentials(authenticationResult.AccessToken, "Bearer");

// Create a Power BI Client object (it will be used to call Power BI APIs)
using (var client = new PowerBIClient(new Uri(ApiUrl), tokenCredentials))
{
	var dataset = client.Datasets.GetDatasetByIdAsync("My dataset id");
}

What type is the dataset? The underlying REST API Get Tables only supports  push datasets and hybrid datasets(streaming dataset with historic data analysis enabled).
