CAS also determines what resources a code can access when it is running.COM inter-op - COM inter-op enables you to use existing COM objects while transitioning to the .NET framework at your own pace. Using COM inter-op, COM-programs can be provided with a .NET label and accessed similar to a .NET class and vice versa.
回答：错误处理——一个错误事件发生在正常程序流执行时遇到扰乱或中断的时候。.NET提供了结构化的异常处理方法，它能给出详细的错误信息和提供一些小错误的处理方法。

数据访问安全性（CAS）——是.NET安全模型的组成部分，在.NET运行时，它能决定某一小段程序是否能被执行和具体某个程序被允许执行。

COM inter-op——COM inter-op通过改变原有的COM对象以转化成能被你使用的.NET模型。在运行COM inter-op时，COM程序上课见一个.NET模型的标签，这时和.NET相似的类也可以进入COM程序，反之亦然。
