Is your feature request related to a problem? Please describe.

Describe the solution you'd like
I suggest to run a Code Cleanup from VS Studio to normalize the formatting and the imports throughout the source code.

Additional context

There will be on the order of 1880 files modified.

Here is an example of what would happen.
