  NameDescription
Protected methodAbortWhen implemented in a derived class, takes actions in response to the activity being aborted. (Inherited from NativeActivity.)
Protected methodCacheMetadata(ActivityMetadata)Not implemented. Use the CacheMetadata(NativeActivityMetadata) method instead. (Inherited from NativeActivity.)
Protected methodCacheMetadata(NativeActivityMetadata)Creates and validates a description of the activity’s arguments, variables, child activities, and activity delegates. (Inherited from NativeActivity.)
Protected methodCancelWhen implemented in a derived class, runs logic to cause graceful early completion of the activity. (Inherited from NativeActivity.)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodExecuteWhen implemented in a derived class, runs the activity’s execution logic. (Inherited from NativeActivity.)
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.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodShouldSerializeDisplayNameIndicates whether the DisplayName property should be serialized. (Inherited from Activity.)

When this activity begins executing, a new Transaction is started if one does not already exist. The transaction commits when the activity and all other participants in the transaction have completed successfully.

The following code sample demonstrates creating a TransactionScope activity. This example is from the Nesting of TransactionScope sample.

C#
Copy 

new TransactionScope
{
    Body = new Sequence
    {
        Activities = 
        {
            new WriteLine { Text = "    Begin TransactionScope" },

            new PrintTransactionId(),

            new TransactionScopeTest(),

            new WriteLine { Text = "    End TransactionScope" },
        },
    },
},
