Assembly:  System.Runtime.DurableInstancing (in System.Runtime.DurableInstancing.dll)

protected internal virtual IAsyncResult BeginTryCommand(
	InstancePersistenceContext context,
	InstancePersistenceCommand command,
	TimeSpan timeout,
	AsyncCallback callback,
	Object state
)

Parameters

context
Type: System.Runtime.DurableInstancing.InstancePersistenceContext
