Question

我只是想运行一个简单的NServiceBus Pub / Sub示例。基本上，我有pub / sub作为控制台应用程序，当我运行它时，我在子方面得到一个例外。

Exception was unhandled by user code
  Message=Exception when starting endpoint, error has been logged. Reason: Error creating object with name 'NServiceBus.Unicast.UnicastBus' : Error setting property values: PropertyAccessExceptionsException (1 errors); nested PropertyAccessExceptions are: 
[Spring.Core.TypeMismatchException: Cannot convert property value of type [System.Collections.Hashtable] to required type [System.Collections.IDictionary] for property 'MessageOwners'., Inner Exception: System.ArgumentException: Problem loading message assembly: Messages ---> System.IO.FileNotFoundException: Could not load file or assembly 'Messages' or one of its dependencies. The system cannot find the file specified.
File name: 'Messages'

看起来我缺少名为“消息”的程序集，但我不确定在哪里可以找到它。

感谢。

Answer 1

最有可能是你在UnicastBusConfig中指定了“消息”（可能是从其中一个样本中复制配置而遗留下来的。）

Answer 2

我不完全是问题所在，但是，您必须确保您的消息类型位于单独的程序集中，并且您的Message类实现了NServiceBus IMessage接口。

此外，你的Pub和Sub都需要引用你的Messages组件（显然你可以调用任何东西，你不必称之为Message）。

例外“无法加载文件或程序集'消息'或其依赖项之一。” NServiceBus
