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

[SecurityPermissionAttribute(SecurityAction.InheritanceDemand, Flags = SecurityPermissionFlag.NoFlags|SecurityPermissionFlag.ControlEvidence|SecurityPermissionFlag.ControlPolicy)]
public class SynchronizationContext

The SynchronizationContext class is a base class that provides a free-threaded context with no synchronization.

The purpose of the synchronization model implemented by this class is to allow the internal asynchronous/synchronization operations of the common language runtime to behave properly with different synchronization models. This model also simplifies some of the requirements that managed applications have had to follow in order to work correctly under different synchronization environments.

Providers of synchronization models can extend this class and provide their own implementations for these methods. 

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