Blazor: Why System.Xml?

[LukeTOBrien]

Hello,

For a while now I have been trying to to remove dependencies in the hope of lowering the download size and minimizing the number of DLLs my app needs.
One of the DLLs that I have not been able the remove is System.Xml.dll (and it's sister System.Linq.Xml.dll)
This file is about 1.5MB (sometimes smaller) and is one of the biggest dependencies my app has, it is also the most complexing mystery to me as all HTTP request are in JSON and I don;t know what is using it.

It seems to me that System.Xml.dll is used in the Blazor framework, here is the default app template (albeit 3.2.0 RC1):

So my question is, where is System.Xml being used and can it be removed?
