.NET Framework Class Library

ContextBoundObject Class

Defines the base class for all context-bound classes.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

C++

JScript

'Usage

Dim instance As ContextBoundObject

'Declaration

<ComVisibleAttribute(True)> _
Public MustInherit Class ContextBoundObject _
    Inherits MarshalByRefObject

Remarks

Objects that reside in a context and are bound to the context rules are called context-bound objects. A context is a set of properties or usage rules that define an environment where a collection of objects resides. The rules are enforced when the objects are entering or leaving a context. Objects that are not context-bound are called agile objects.

Contexts are created during object activation. A new object is placed into an existing context or into a new context created using the attributes included in the metadata of the type. Context-bound classes are marked with a ContextAttribute that provides the usage rules. The context properties that can be added include policies regarding synchronization and transactions.

Notes to Implementers:

The current version of the common language runtime does not support generic ContextBoundObject types or nongeneric ContextBoundObject types that have generic methods. Attempting to create an instance of such a type causes a TypeLoadException.

For more information, see the "Limitations of Generics" subsection of the Overview of Generics in the .NET Framework topic.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
