Dataset relationships through the API

[TBardien]

How do I get the Dataset relationships through the API?

So, I am trying to call "client.Datasets.PostDatasetInGroupAsync(Guid groupId, CreateDatasetRequest dataset)" 

I have the groupID, so I am trying to create the "CreateDatasetRequest dataset".

"CreateDatasetRequest " is a class that looks like this:

public string Name { get; set; }
public IList<Table> Tables { get; set; }
                      public IList<Relationship> Relationships { get; set; }
                   public IList<Datasource> Datasources { get; set; }
              public DatasetMode? DefaultMode { get; set; }

I need the Tables, the Relationships and the Datasources.

My dataset is basically a copy of another dataset, and I am getting the information from the copied datasource.

I can get Tables like this: client.Datasets.GetTablesInGroupAsync(workspaceId, datasetID);

NOTE: client.Datasets.GetTablesInGroupAsync(workspaceId, datasetID); does not seem to work. it throws a NOT FOUND ERROR.

and the datasource like this: client.Datasets.GetDatasourcesInGroupAsync(workspaceId, datasetID);

But I cannot find a way to get the Relationships.

Is there a way that I can do this?

Connect to the XMLA endpoint and run your XMLA scripts aganst the DMVs.  Use DAX Studio or similar to experiment with that.
