web.config transform: Add XML comment to indicate which configuration was used

Question

Using web.config transforms, I want to make sure and include a comment at top of the resulting web.config to indicate which transform file(configuration) was used to generate it.

I don't see a way to include comments from the transform files, can this be done?

EDIT:

It appears that all comments in the transform files are stripped.

Answer 1

The following does not directly answer how to add or preserve comments, but it might get you toward the goal of knowing which transform was used. Admittedly, it feels a little strange, so keep your eyes open for other answers. It's just the first thing that came to mind.

I don't know of a way to preserve the comments from transforms, but you could always insert a dummy application setting to deliver the information. The app doesn't actually have to use it for anything =p

Here I have it being inserted by the transform, assuming it isn't in the main web.config. You could just as easily do a Replace.

<appSettings>
    <add key="WhichTransformWasUsed" value="Production" xdt:Transform="Insert"/>
</appSettings>
