_TypeA context intercepts calls to the class members and enforces policies that are applied to the class, such as synchronization. For more detailed information on remoting contexts, see Context.
If the current Type represents a type parameter in the definition of a generic type or generic method, this property always returns false.
The following example demonstrates the IsContextful, IsMarshalByRef, and IsPrimitive properties of the Type class. It checks whether the given type can be hosted in the context, whether it can be marshaled by reference, and whether the type is a primitive data type.
