ADX: unable to ingest data via a control command using .NET sdk

I defined a super-simple talbe:

.create table dummy (textfield: string)

I can properly execute an inline ingest command from Query panel:

.ingest inline into table dummy <| 'from query panel'

But I can't using .NET sdk:

using Kusto.Data;
using Kusto.Data.Common;
using Kusto.Data.Net.Client;
using System;

class Program
{
    static void Main(string[] args)
    {
        var connection = new KustoConnectionStringBuilder("https://ingest-mycluster.westeurope.kusto.windows.net", "tracking")
                 .WithAadApplicationKeyAuthentication(
                     "MY_APPREG_ID",
                     "MY_APPREG_SECRET",
                     "MY_APPREG_TENANT");

        var client = KustoClientFactory.CreateCslAdminProvider(connection);

        client.ExecuteControlCommand(".ingest inline into table dummy <| 'from dot net'");

        //var cmd = CslCommandGenerator.GenerateTableIngestPushCommand("dummy", true, "textfield\ndotnettest");
        //client.ExecuteControlCommand(cmd);

        Console.WriteLine("completed");
    }
}

I've also tried with CslCommandGenerator bust still always getting same exeception:

  This exception was originally thrown at this call stack:
    [External Code]
    Program.Main(string[]) in Program.cs

It reports a syntax error, but the command query is valid.

What am I missing?

I'm using the ingestion URI, and it's wrong.

The correct is: https://mycluster.westeurope.kusto.windows.net
