我将View variables模块安装到我的XAF winforms 21.2.7项目中，它' '在我的机器上工作' ';
当我部署和运行时，我得到一个错误，以下调用堆栈记录在eXpressAppFramework.Log

我可以通过打开应用程序的预览副本并登录来解决这个问题。
之后，我可以成功地使用应用程序。
或者我可以从用户漫游应用程序文件夹中删除文件ModulesVersionInfo以使应用程序成功打开
从应用程序文件夹中删除modelassembly.dll也可以解决这个问题。
从部署中删除ModelAssembly.Dll解决了这个问题。当应用程序打开时，dll将被正确创建。
