Examples

The following example shows how to access the ServiceOperationInfo property. This code was adapted from the Conversations SDK sample, from the ShipperWorkflow.designer.cs file.

ReceiveActivity receiveQuoteFromShipper1 = new ReceiveActivity();
CodeActivity shipper1ShippingQuote = new CodeActivity();
ContextToken contextToken1 = new ContextToken();
ActivityBind activityBind1 = new ActivityBind();
WorkflowParameterBinding workflowParameterBinding1 = new WorkflowParameterBinding();
TypedOperationInfo typedOperationInfo1 = new TypedOperationInfo();

receiveQuoteFromShipper1.Activities.Add(shipper1ShippingQuote);
contextToken1.Name = "Shipper1Context";
contextToken1.OwnerActivityName = "GetShippingQuotes";
receiveQuoteFromShipper1.ContextToken = contextToken1;
receiveQuoteFromShipper1.Name = "receiveQuoteFromShipper1";
activityBind1.Name = "SupplierWorkflow";
activityBind1.Path = "quoteShipper1";
workflowParameterBinding1.ParameterName = "quote";
workflowParameterBinding1.SetBinding(WorkflowParameterBinding.ValueProperty, ((ActivityBind)(activityBind1)));
receiveQuoteFromShipper1.ParameterBindings.Add(workflowParameterBinding1);
typedOperationInfo1.ContractType = typeof(IShippingQuote);
typedOperationInfo1.Name = "ShippingQuote";
receiveQuoteFromShipper1.ServiceOperationInfo = typedOperationInfo1;

Remarks

The ServiceOperationInfo property can be set to an instance of type TypedOperationInfo or OperationInfo. TypedOperationInfo can be used to configure a receive activity using an existing Windows Communication Foundation (WCF) service contract.

An instance of OperationInfo can be used to configure a receive activity for the workflow-first contract scenario.
