A complete WiX 3.6 bundle example bootstrapping a .NET 4 Client Profile

I tried to construct a working example of a WiX 3.6 installation script. We currently use WiX 3.5 and now we would like to begin installing the .NET 4 Client Profile framework as a pre-requisite for our MSI file that our product.wxs script creates. WiX 3.6 seems like the best way forward.

Is there a functional example of how to do this with WiX 3.6?

Here is our 3.5 script we use today:

    <?ifdef env.BUILD_NUMBER ?>
    <?define ProductVersion="2.6.$(env.BUILD_NUMBER).0"?>
    <?else ?>
    <?define ProductVersion="2.6.0.0"?>
    <?endif ?>

    <Product Id="*" Name="###############################" Language="1033" Version="$(var.ProductVersion)" Manufacturer="###############################" UpgradeCode="$(var.UpgradeCode)">
        <Package InstallerVersion="200" Compressed="yes" />

        <!-- Custom actions for this installer -->
        <Binary Id="###############################.dll" SourceFile="..\..\Libraries\###############################.CA.dll" />

        <!-- Kill ##### before installation begins -->
        <CustomAction Id="Kill#####ActionId" BinaryKey="###############################.dll" DllEntry="Kill#####Action" Execute="immediate" Impersonate="yes" Return="check" />
        <InstallExecuteSequence>
            <Custom Action="Kill#####ActionId" Before="InstallInitialize" />
        </InstallExecuteSequence>
