This first release contains the following:
An installer that will install the WCFActivities assembly in the GAC. It will also register the assembly with visual studio and you can reference the activities from your toolbox using the "Choose Toolbox Items" dialog Activities TAB.
It also contains a step by step guide how you can use the activities.
The input and output activities have the following features:
You can pick and choose any interface you want that contains methods you want to expose as a service operation
It will auto generate a class with a <workflowName>_wcfContractImpl class that contains a contract implementation
You can specify the service namespace and Name on the root workflow that uses the WCF activities (this is accomplished with Attached properties)
You can specify some WCF attributes on the input activites that will be reflected in the generated implementation.
Supported attributes currently are: Action, IsOneWay, AsyncPattern, ProtectionLevel and NameSpace at the root workflow level.
