VMSS extensions in linked ARM template
I have a scale set with 5 extensions. 2 of them are for Service Profiler, to install .net 4.6.1, and for the service profiler agent itself. When I deploy the template with all 5 extensions, due (I think..) to the .net installation requiring a restart of the vm, the template will always result in a status of failed. However, it doesn't seem to have actually failed, as when the vm restarts, it resumes any extensions that haven't finished (again, I think.. Unfortunately, my project isn't in the position to be able to test this infrastructure with an application atm).
So, I have attempted to move the 2 service profiler extensions to a linked template, so the status of the scale set will go to succeeded, and actions after this won't be impacted. (As well as other resources in the template being dependent on the scale set, I assume application deployment from VSTS release manager won't happen if the infrastructure deployment 'failed'.)
So my linked template simply has the scale set resource, but with only the extensions defined:

}
However, I get this error message:

Seems kind of strange considering I'm not trying to delete anything. And ofc there is literally nothing, as far as I can tell, in the documentation about extensions in linked templates, or anywhere else...
Is this even supported? Or should I just leave it in 1 template? Any help would be great!

Here is my full scale set resource, with all extensions in the single template. It originally didn't work, but it does now...

the error message about deleting extensions is because the extension list is applied as a whole, so if you don't have the two original extensions (from the main template) it will think you are deleting them. I.e. you'd need to include all 4 extensions in the list. The suggestion in the comments of using a custom image with .Net installed is a good one. Another option for getting information on to the machine is to use the customData property - though it probably won't help this specific case.
There are some requests to create a platform image with latest .Net installed (I'm wondering whether any of the marketplace images already have this), and I think we should do it.
