Namespace:  System.Windows.Threading
Assembly:  WindowsBase (in WindowsBase.dll)
XMLNS for XAML: Not mapped to an xmlns.

public sealed class DispatcherSynchronizationContext : SynchronizationContext

The DispatcherSynchronizationContext type exposes the following members.

Public methodDispatcherSynchronizationContext()Initializes a new instance of the DispatcherSynchronizationContext class by using the current Dispatcher.
Public methodDispatcherSynchronizationContext(Dispatcher)Initializes a new instance of the DispatcherSynchronizationContext class by using the specified Dispatcher.

Public methodCreateCopyCreates a copy of this DispatcherSynchronizationContext. (Overrides SynchronizationContext.CreateCopy().)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsWaitNotificationRequiredDetermines if wait notification is required. (Inherited from SynchronizationContext.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodOperationCompletedWhen overridden in a derived class, responds to the notification that an operation has completed. (Inherited from SynchronizationContext.)
Public methodOperationStartedWhen overridden in a derived class, responds to the notification that an operation has started. (Inherited from SynchronizationContext.)
Public methodPostInvokes the callback in the synchronization context asynchronously. (Overrides SynchronizationContext.Post(SendOrPostCallback, Object).)
Public methodSendInvokes the callback in the synchronization context synchronously. (Overrides SynchronizationContext.Send(SendOrPostCallback, Object).)
Protected methodSetWaitNotificationRequiredSets notification that wait notification is required and prepares the callback method so it can be called more reliably when a wait occurs. (Inherited from SynchronizationContext.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodWaitWaits for any or all the elements in the specified array to receive a signal. (Overrides SynchronizationContext.Wait(IntPtr[], Boolean, Int32).)

If a Dispatcher is not specified at the creation of the DispatcherSynchronizationContext instance, the current Dispatcher is associated with the DispatcherSynchronizationContext.
