WCF 服务中的事务范围异常

Question

我正在尝试在 wcf 服务中使用 enble 事务流。

但是我收到以下错误：

  The header 'OleTxTransaction' from the namespace 'http://schemas.microsoft.com/ws/2006/02/tx/oletx' was not understood by the recipient of this message, causing the message to not be processed.  This error typically indicates that the sender of this message has enabled a communication protocol that the receiver cannot process. Please ensure that the configuration of the client's binding is consistent with the service's binding. 

这是我尝试运行的代码的代码片段：

var transactionOptions = new TransactionOptions
                                 {
                                     IsolationLevel = IsolationLevel.ReadCommitted
                                 };
using (var transaction = new TransactionScope(TransactionScopeOption.Required, transactionOptions))
        {
            try
            {
                var company = CreateCompanyDto(settings);
                if (settings.Institution.CompletedSetup)
                {
                    _ezFinanceCompanyServiceLibrary.UpdateCompany(company); // This is the wcf call.
                }
                else
                {
                   _ezFinanceCompanyServiceLibrary.CreateCompany(company); // This is the wcf call.
                    CreateDefaultInventroyItems(company.EntityGuid);
                }
                _db.SaveChanges();
                transaction.Complete();
                return true;
            }
            catch (Exception exception)
            {
                _log.Error(exception.Message);
                return false;
            }
        }

这是我在 Web API 的 web.config 上的绑定选项

<bindings>
  <netTcpBinding>
    <binding name="netTcpBindingbehavior" transactionFlow="true" portSharingEnabled="true" />
  </netTcpBinding>
  <netMsmqBinding>
    <binding name="netMsmqBinding">
      <security mode="None" />
    </binding>
  </netMsmqBinding>
</bindings>

我在 WCF 中的服务接口上有操作协定

[OperationContract]
[TransactionFlow(TransactionFlowOption.Allowed)]
int CreateCompany(CompanyDto newCompany);
[OperationContract]
[TransactionFlow(TransactionFlowOption.Allowed)]
int UpdateCompany(CompanyDto Company);

我在公开的方法上有以下属性

[OperationBehavior(TransactionScopeRequired = true)]

wcf 服务中应用程序.config 上的绑定选项

<bindings>
  <netTcpBinding>
    <binding name="netTcpBinding" transactionFlow="true" portSharingEnabled="true" />
  </netTcpBinding>
</bindings>

我已启用网络 DTC 访问，我允许 Inbounnd 和出站，我没有选中身份验证要求。我已启用 XA 事务和 SNA LU 6.2 事务

我尝试将以下属性添加到我的绑定中：

transactionProtocol="OleTransactions"

在服务和 Web API 上。

似乎无法弄清楚问题是什么。

事实证明，WCF 方法调用的方法上放置了[OperationContract]属性，这些方法已经具有删除所有[OperationContract]属性并仅将它们放置在 WCF 公开的方法上[OperationContract]解决了该问题。
