wix 3.6 ComponentGroupRef Id="Product.Generated" gives error, wix 3.5 does not

Question

I just updated wix to 3.6 and after the upgrade my wix project failed to build.

The following line in the xml triggers the error:

<ComponentGroupRef Id="Product.Generated"/>

The error explanation is the following:

error LGHT0094: Unresolved reference to symbol 'WixComponentGroup:Product.Generated' in section 'Product:*'.

If I comment out the ComponetGroupRef element, the msi is created without any errors and it seems to work just as before the upgrade to 3.6.

Fails:

<Feature Id="ProductFeature" Title="My.net Server" Level="1">
   <ComponentRef Id="My.Server" />
   <ComponentRef Id="My.Server.exe.config"/>
   <!-- Note: The following ComponentGroupRef is required to pull in generated authoring from project references. -->
   <ComponentGroupRef Id="Product.Generated" />
</Feature>

Works:

<Feature Id="ProductFeature" Title="My.net Server" Level="1">
   <ComponentRef Id="My.Server" />
   <ComponentRef Id="My.Server.exe.config"/>
</Feature>

Could anyone shed some light on this error? Am I breaking something that I should be aware of or fix? How important is that entry and what exactly does it do?
