Kusto客户端无法向服务发送请求：请求标头必须仅包含ASCII字符

Question

我正在使用以下代码生成连接字符串

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);

但是当我运行如下命令时

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

    client.ExecuteControlCommand(command);
}

我不断收到错误“Kusto客户端无法向服务发送请求：请求标头必须只包含ASCII字符。”

我已启用详细跟踪，我发现它仍在尝试连接我的Azure用户而不是AadApplicationKeyAuthentication

这是日志行：

使用的Nuget包：

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

更新：

如果我使用FullFx 4.7.1和他们的NuGetPackages它可以工作！

  <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。从快速浏览一下，我相信它是.NET Framework的HttpClient中HttpClient的行为之间的差距，我们将看一看。
