WiX bootstrapper disable .NET Framework installation chaining

In my WiX installer, I do not want .NET installed automatically if it isn't installed. It should just give a warning or merely error out.

The reason to avoid it is explained here:

One HUGE word of caution here: Because the .Net installer will technically be part of your install chain, if the user installs .Net but then cancels your install, your installer will still be listed in the Add/Remove programs since one if it’s components (the .Net installer) completed. Tread with caution.

He seems to be intentionally including it. But I'm not and I happened to set <supportedRuntime version="v4.5" /> which I guess isn't a real version (4.5 => 4.0 as far as this is concerned?). My WiX managed bootstrapper application exe automatically prompted me to download and install the "missing" .NET Framework.

For computers that ARE missing 4.0, I don't want this to happen. WiX also complains if I leave out:

<WixVariable Id="WixMbaPrereqLicenseUrl" Value="..." />
<WixVariable Id="WixMbaPrereqPackageId" Value="..." />

in which I literally leave in ... because I don't want it to work anyway.

In this thread, @Shruthi asks

Is there a way to replace the prerequisite .Net install UI with just an notification to the user that they need to install a particular version of .Net before they can install the bundle?

And Rob Mensching replies:

Yes, that is possible now.

... BUT HE DOESN'T ELABORATE. How is it possible now?

Thanks!

===============

In my Bundle's Bootstrap.Config:

<startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v6" />  <!-- Pretending it's the future! -->
</startup>

WiX bootstrap stub window?

The Bundle itself does not reference any .NET stuff and does not reference WixNetFxExtension and uses the custom <BootstrapperApplicationRef Id="ManagedBootstrapperApplicationHost" />

To answer how to handle checking for the .Net 4.0 Framework include the WixNetfxExtension in your project

then under product add a reference to the property NETFRAMEWORK40FULL and put a condition on it.

<PropertyRef Id="NETFRAMEWORK40FULL"/>
<Condition Message="This application requires .NET Framework 4.0. Please install the .NET Framework then run this installer again.">
  <![CDATA[Installed OR NETFRAMEWORK40FULL]]>
</Condition>

for the chained case again include wixnetfxextension and include NetFx40Redist package group

<PackageGroupRef Id="NetFx40Redist"/>
