I'm using the following code to generate a connectionstring

var kustoUri = $"https://{clusername}.{region}.kusto.windows.net";
var dmKustoUri = $"https://ingest-{clusername}.{region}.kusto.windows.net";

this.engineKustoConnectionStringBuilder = new KustoConnectionStringBuilder(kustoUri)
    .WithAadApplicationKeyAuthentication(applicationClientId, applicationKey, authority);
this.dmKustoConnectionStringBuilder =
    new KustoConnectionStringBuilder(dmKustoUri)
        .WithAadApplicationKeyAuthentication(applicationClientId, applicationKey, authority);

But when I run a command like below

using (var client = KustoClientFactory.CreateCslAdminProvider(this.engineKustoConnectionStringBuilder))
{
    var command = CslCommandGenerator.GenerateTableCreateCommand(table, columns);

    client.ExecuteControlCommand(command);
}

I continuously get the error "Kusto client failed to send a request to the service: Request headers must contain only ASCII characters."

I've enabled verbose tracing and I see it's still trying to connect with my Azure User instead of the AadApplicationKeyAuthentication

Here is the log line:

Nuget packages used:

<PackageReference Include="Microsoft.Azure.Kusto.Data.NETStandard" Version="6.1.8" />
<PackageReference Include="Microsoft.Azure.Kusto.Ingest.NETStandard" Version="6.1.8" />

UPDATE:

If I use FullFx 4.7.1 and their NuGetPackages it works!

  <package id="Microsoft.Azure.Kusto.Data" version="6.1.8" targetFramework="net471" />
  <package id="Microsoft.Azure.Kusto.Ingest" version="6.1.8" targetFramework="net471" />

感谢您报告此事，@JSC。快速浏览一下，我相信这是 .NET Framework 的 HttpClient 中 HttpClient 的行为之间的差距，我们将看看。
