ICE框架双工通讯+MVVM框架测试案例

准备

开发工具 VS2015

ICE框架 https://zeroc.com/

MVVMLight框架

ICE接口文件 

#include "./Identity.ice"
#include "./CommonIPC.ice"

module Demo {
    interface ServerProxy {
        void Register(Ice::Identity ident);
        int GetResultFromServer();
    };

    interface ClientProxy {
        bool SendToClient(string i);
    };
};

预编译指令 （BuildEvent）

echo Setting path for Pre-build event  > iceout.txt
set PATH=$(SolutionDir)3.6.2;%PATH% >> iceout.txt

echo Calling slice2cs on Printer.ice >> iceout.txt
slice2cs.exe --output-dir $(ProjectDir)ICEGenerated $(ProjectDir)Printer.ice >> iceout.txt 2>&1

第一条是 预编译结果输出，成功失败异常等

第二条是开始预编译（自动生成接口文件相关）
