Sequence workflow = new Sequence
{
    Variables = { mealExpense, result },
    Activities =
        {
            new Assign<Expense>
            {
               Value = new InArgument<Expense>( (e) => new Meal { Amount = 50, Location = "Redmond", Vendor = "KFC" }),
               To = new OutArgument<Expense>(mealExpense)
            },
            new WriteLine 
            {
                Text = new InArgument<string>("Hello")
            },
            approveExpense,
            new ReceiveReply
            {
                Request = approveExpense,                            
                Content = ReceiveContent.Create(new OutArgument<bool>(result))
            },

            new If
            {
               Condition = new InArgument<bool> (result),
               Then =                         
                    new WriteLine
                    {
                        Text = new InArgument<string>("Expense Approved")
                    },
               Else =                         
                    new WriteLine
                    {
                        Text = new InArgument<string>("Expense Cannot be Approved")
                    },
            },
