使用.NET框架编写Windows程序，在很多方面已经变得很简单。在许多情况下，.NET框架使用，.NET编译器在编译时绑定到程序集的元数据，.使灵活的程序设计变得更容易。事实上，对于.NET而言，使用内嵌的元数据把我们从DLL地狱解脱出来是可能的。(Writing Windows programs using the.NET framework has become very simple in many ways. In many cases, the.NET framework uses metadata that is bound to the assembly at compile time by the.NET compiler, making it easier to program flexibly. In fact, it is possible for.NET to use nested metadata to free us from DLL hell.)
