Not applicable.
You can apply this attribute to classes, structures, enumerations, and interfaces.
For example, you can use this attribute to mark a C++ class that has a copy constructor. Any compiler that uses such a class must understand every constraint on its use, such as never creating an object of that class in the garbage collected heap, because a relocation does not call its copy constructor.
The classes in System.Runtime.CompilerServices are for compiler writers use only.
