The following example shows how to use the ReceiveContent class to specify the content for a Receive activity.


return new Sequence
{
    Variables = { po, customer },
    Activities =
    {                    
        new Assign<PurchaseOrder> 
        {
            To = po,
            Value = new InArgument<PurchaseOrder>( (e) => new PurchaseOrder() { PartName = "Widget", Quantity = 150 } )
        },
        new Assign<Customer>
        {
            To = customer,
            Value = new InArgument<Customer>( (e) => new Customer() { Id = 12345678, Name = "John Smith" } )
        },
        new WriteLine { Text = new InArgument<string>( (e) => string.Format("Submitting new PurchaseOrder for {0} {1}s", po.Get(e).Quantity, po.Get(e).PartName) ) },
        new CorrelationScope

        new Assign<int> 
        { 
            To = new OutArgument<int>( (e) => po.Get(e).CustomerId ), 
            Value = new InArgument<int>( (e) => customer.Get(e).Id )
        },
        new WriteLine { Text = "Updating customer data based on CustomerId." },
        new Send
