Specifies that an importing compiler must fully understand the semantics of a type definition, or refuse to use it. This class cannot be inherited.

Remarks

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.

Constructors
