Question

我正在使用VSTO 2008开发一个简单的Outlook 2003加载项。在开发环境中一切正常。但是当我尝试安装插件时，会出现以下加载错误。我认为存在一些与安全相关的问题。请帮我解决这个问题。

System.Security.Policy.PolicyException: Execution permission cannot be acquired.

VSTO部署要求您向已部署的解决方案依赖项授予信任。 “Solutions to Common Issues encountered during Outlook Add-in development”和“Deploying Visual Studio 2005 Tools for the Office”是一些文章，通过一些不同的方式可以修改代码访问安全性（CAS）以使VSTO解决方案正常工作。
