CorrelationScope
This activity provides implicit CorrelationHandle management for child messaging activities.
Activity Parameters
The CorrelationScope activity has one parameter and it can be provided by manually inserted values or via IN arguments or variables:
...
- CorrelatesWith (text box editor type) (type: CorrelationHandle): Specifies the CorrelationHandle used to manage child messaging activities. If you do not set this property, CorrelationScope creates an implicit CorrelationHandle automatically.
InitializeCorrelation
This activity is used to initialize correlations without sending or receiving a message. Typically correlation is initialized when sending or receiving a message. If correlation must be established before a message is sent or received, use InitializeCorrelation to initialize the correlation.
Activity Parameters
The InitializeCorrelation activity has three parameters (including DisplayName) that can be provided by manually inserted values or via IN arguments or variables:
Parameters:
- Correlation (text box editor type) (type: CorrelationHandle): The CorrelationHandle used to associate workflow activities in the correlation.
- CorellationData (collection editor type) (type: Collection): A dictionary of correlation data that relates messages to the workflow instance.
Receive
This activity is an activity that receives a message that can be either a built-in type such as Message, Stream or XElement, or an application-defined data contract, message contract, or XML class that can be serialized.
Activity Parameters
