C# WCF 的行为类似于单个用户实例

Question

我开发了一个在 IIS 中运行的新 WCF 服务和一个使用此服务的 ASP.NET Web 应用程序。在服务器上运行它时它工作正常。但是，当我通过 IE 浏览器和 Chrome 浏览器以多个用户(2 个用户)身份访问该服务时，我注意到当第二个用户登录时，他们看到的是与第一个用户 session 相关的数据，这使得超过 1 个用户无法访问一次使用该服务。我曾假设 WCF 服务会在服务配置后自动处理多个 session : [服务行为(InstanceContextMode=InstanceContextMode.PerSession)]

但似乎并不是这样。下面是我如何在服务中定义我的类以及如何初始化 MyGlob。如果有人能指出我做错了什么，我将不胜感激？

public UserMaster LoadUserDtls(string loggedInUserId, string userPassword)
      {
      try
         {
          // Create all objects required to bootstrap initial menu transaction
                MyGlob.CrtUserMaster();
                MyGlob.CrtEnterpriseMaster();
                MyGlob.CrtDataBaseIO();
                MyGlob.CrtExecuteTrans();
                MyGlob.CrtErrorMsgs();
                MyGlob.CrtPromptMsgs();
                MyGlob.CrtConnectionStrings();
                MyGlob.CrtLogMessages();
                MyGlob.CrtRuleTypeOpSeq();
                MyGlob.CrtErrMsgsList();
                MyGlob.CrtEnvironments();
                MyGlob.CrtPromptMsgsList();
                MyGlob.CrtConnStringList();
                MyGlob.CrtEnvironmentList();
                MyGlob.CrtLogMessagesDict();
                MyGlob.CrtRuleTypeOpSeqDict();
                MyGlob.CrtKeywordsDict();
                MyGlob.CrtCommands();
                MyGlob.CrtObjDict();
                MyGlob.CrtNextNumbers();
                MyGlob.CrtAppDistLstDict();
                MyGlob.CrtNextNumbersDict();
                g.MyDataBaseIO.ReceiveMyGlob(MyGlob);
                g.MyCommands.ReceiveMyGlob(MyGlob);

您的问题是“static”关键字。任何“静态”类都将在应用程序加载到内存中时创建一次。因此，单个实例将在所有请求之间共享。
