使用注意：建立demo数据库，使用aspnet_regsql.exe建立Memmbership一些安全场景需要证书，使用CertTool的工具生成具体的授权时的角色和用户名字参考HostSvc、Client代码修改成测试用的后才能正常运行 一、目录结构Common来自于Programming WCF Services[ISBN: 978-0-596-80548-7]，实现WCF的声明式安全HostSvc：不同场景的接口和服务实现，命令行承载服务MembershipAdmin：用于操作demo数据库membership的成员操作，Asp.net Configuraion 可添加角色和用户，并使用IIS服务承载HostSvc实现的服务Client: 使用各种服务的客户端场景 二、四种场景的区别：Intranet Transport保护 使用tcp绑定 windows集成的安全 Internet 只能使用Message形式的保护，需要数字证书 tcp wsHttp绑定 使用Membership进行安全认证 Anoymous 使用Message形式的保护，需要数字证书 tcp wsHttp绑定 None 消息不保护  http tcp wsHttp绑定 三、App-comment.config： 包含对于各种配置的说明 四、证书的生成：CertToolSetupCerts.bat生成，命令行工具从VS SDK已经拷贝过来 五、IIS中承载服务的注意： 需要把WCFServer赋予IIS的账号以权限 受信任人中加入WCFServer证书 六、证书如何管理：1、命令行启动mmc2、“添加、删除管理单元"加入"证书", 按照提示选择当前用户或本机3、此时即可管理IIS的权限操作： 在"个人/证书"下找到WCFServer,"更多操作/所有任务/管理私钥",弹出界面设置用户权限受信任人： 在"个人/证书"下找到WCFServer，导出证书，然后在”受信息人/证书“下导入以上证书即可 七、远程机器客户端的证书问题 导出WCFServer【不要私钥】 然后在远程客户端机器上导入即可，此时的公钥可以用于消息的验证 八、IIS中承载MembershipAdmin中加入了对应的四个.svc文件【逻辑使用的一个HostSvc中的实现】以提供WCF服务，具体配置和HostSvc一致，当然地址不一样了此例是把MembershipAdmin作为应程序发布到80端口的demo下 注意:1、需要设置IIS的http和net.tcp协议支持2、数据库demo需要能被IIS账号访问3、WCFServer证书需要能被IIS账号访问

说明：  个人编写的基于.net的socket的局域网点对点聊天程序，打开两个程序，一个设置好ip后开始监听个，另一个放到局域网内别的电脑上设置ip连接之前的监听程序(Net socket based LAN point-to-point chat program, open two programs, one set up IP to start listening, the other put on the LAN other computer before the IP connection)
