注册事件会在客户端上抛出错误 [英] Register for event is throwing an error on the client
问题描述
我已经设置了一个服务器，2个客户端。我需要做的是在向服务器发送新消息时注册事件，以便客户端可以接收它。
服务器启动良好
客户端建立良好连接并且所有属性都是通过构造函数设置的，
现在当我在客户端注册一个事件时，我得到一个异常：
调用的目标抛出了异常。 br>
message = {"无法加载文件或程序集'AFCCIncChatAppClient，Version = 1.0.0.0，Culture = neutral，PublicKeyToken = null'或其依赖项之一。系统找不到指定的文件。"："AFCCIncChatAppClient，Version = 1.0.0.0，Culture = neutral，PublicKeyToken = null"}

I have set up a server, 2 clients. What I need to do is register for an event when ever a new message is sent to the server so that the client can receive it.
The server starts fine
The client makes a good connection and all propertes are set via the constructor,
Now when I get to registering for an event on the client I get an exception:
Exception has been thrown by the target of an invocation.
message = {"Could not load file or assembly 'AFCCIncChatAppClient, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.":"AFCCIncChatAppClient, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"}

推荐答案
我认为您需要定义委托" AFCCIncChatterWrapper 。 UserBase 。 NewMessageDelegate "在一个强名称签名的图书馆里面。该库应安装在服务器端和客户端。
I think you need to define the delegate "AFCCIncChatterWrapper.UserBase.NewMessageDelegate" inside a library which is strong-name signed. This library should be installed on both the server and the client side.
