NServiceBus，找不到消息类型的传奇

Question

我下面的传奇不处理 ValidateRegistration 和 ValidateRegistration 命令。我看到“无法找到消息类型 Registrations.Messages.ValidateRegistration with id ... 的传奇”消息。

我查找传奇的配置不正确吗？请帮忙!

谢谢

PS:我在注册过程中使用通用主机，并且使用 NServiceBus.Lite 配置文件。

您的 StartRegistration 处理程序未将 RegistrationID 添加到 Saga 的数据中。因此，您对ConfigureHowToFindSaga 的覆盖被映射到在处理其他命令时没有任何值的属性上。
