DotShoppingCart Suite comes with a separate windows service called OrderPipeline. If you don't want to run OrderPipeline as a windows service, here is how you can move it inside the web application.

1. Copy the following lines into configSections of web.config.

<section name="orderPipelineServiceConfiguration" type="DotShoppingCart.OpenSource.Core.OrderPipelineServiceConfigurationSection, DotShoppingCart.OpenSource.Core"/>
<section name="taskConfiguration" type="DotShoppingCart.OpenSource.Core.TaskConfigurationSection, DotShoppingCart.OpenSource.Core"/>

2. Copy the following lines into web.config

     <orderPipelineServiceConfiguration defaultProvider="">
        <providers>
            <!-- name must match with the entries in DSC_OrderPipeline_Processor_lkp, DSC_Order_Status_lkp -->

            <add name="OrderConfirmationEmail" type="DotShoppingCart.Commercial.OrderPipeline.ComOrderEmailProcessorProvider, DotShoppingCart.Commercial.OrderPipeline" emailTemplate="OrderConfirmation" />
            <add name="CreditCardAuthorization" type="DotShoppingCart.OpenSource.OrderPipeline.CreditCardProcessorProvider, DotShoppingCart.OpenSource.OrderPipeline" action="Authorization" />
            <add name="CreditCardCapture" type="DotShoppingCart.OpenSource.OrderPipeline.CreditCardProcessorProvider, DotShoppingCart.OpenSource.OrderPipeline" action="Capture" />
            <add name="PaypalExpressCapture" type="DotShoppingCart.OpenSource.OrderPipeline.PaypalExpressProcessorProvider, DotShoppingCart.OpenSource.OrderPipeline" action="Capture" />
            <add name="OrderCompleteEmail" type="DotShoppingCart.Commercial.OrderPipeline.ComOrderEmailProcessorProvider, DotShoppingCart.Commercial.OrderPipeline" emailTemplate="OrderComplete" />
            <add name="GoogleCheckoutCapture" type="DotShoppingCart.Commercial.OrderPipeline.GoogleCheckoutProcessorProvider, DotShoppingCart.Commercial.OrderPipeline" action="Capture" />
            <add name="CreateGiftCertificate" type="DotShoppingCart.Commercial.OrderPipeline.CreateGiftCertificateProcessorProvider, DotShoppingCart.Commercial.OrderPipeline" />
            <add name="RecurringBillingUpdate" type="DotShoppingCart.Commercial.OrderPipeline.RecurringBillingUpdateProcessorProvider, DotShoppingCart.Commercial.OrderPipeline" />
            <add name="GoogleCheckoutShipAndArchive" type="DotShoppingCart.Commercial.OrderPipeline.GoogleCheckoutProcessorProvider, DotShoppingCart.Commercial.OrderPipeline" action="ShipAndArchive" />
            <add name="RecurringInvoiceEmail" type="DotShoppingCart.Commercial.OrderPipeline.ComOrderEmailProcessorProvider, DotShoppingCart.Commercial.OrderPipeline" emailTemplate="RecurringInvoice" />
            <add name="RecurringOrderProcess" type="DotShoppingCart.Commercial.OrderPipeline.RecurringOrderProcessorProvider, DotShoppingCart.Commercial.OrderPipeline" />
        </providers>
    </orderPipelineServiceConfiguration>

    <taskConfiguration defaultProvider="">
        <providers>
            <add name="DataRefresh" type="DotShoppingCart.OpenSource.OrderPipeline.DataRefreshTaskProvider, DotShoppingCart.OpenSource.OrderPipeline" />
            <add name="EmailCampaign" type="DotShoppingCart.Commercial.OrderPipeline.EmailCampaignTaskProvider, DotShoppingCart.Commercial.OrderPipeline" dailyMaxCount="5000" />
            <add name="DailyCleanup" type="DotShoppingCart.Commercial.OrderPipeline.DailyCleanupTaskProvider, DotShoppingCart.Commercial.OrderPipeline" taskRunInterval="1440" startat="160" />
            <add name="TopSellerReset" type="DotShoppingCart.Commercial.OrderPipeline.TopSellerResetTaskProvider, DotShoppingCart.Commercial.OrderPipeline" taskRunInterval="43200" startat="200" />
        </providers>
    </taskConfiguration>

3. Change Global.asax

Add the following line
<%@ Import namespace="DotShoppingCart.OpenSource.OrderPipeline" %>

Change the following methods

void Application_Start(object sender, EventArgs e) {
    OrderPipelineController.Start();
}

void Application_End(object sender, EventArgs e) {
    OrderPipelineController.Stop();
}

4. Copy  *.dll from OrderPipeline directory to web\bin directory
