* Silence dotnet format IDE0059 warnings

* Address or silence dotnet format IDE1006 warnings

* Address dotnet format CA1816 warnings

* Address most dotnet format whitespace warnings

* Run dotnet format after rebase and remove unused usings

- analyzers
- style
- whitespace

* Add comments to disabled warnings

* Remove a few unused parameters

* Adjust namespaces

* Simplify properties and array initialization, Use const when possible, Remove trailing commas

* Start working on disabled warnings

* Fix and silence a few dotnet-format warnings again

* Address a few disabled IDE0060 warnings

* Silence IDE0060 in .editorconfig

* Revert "Simplify properties and array initialization, Use const when possible, Remove trailing commas"

This reverts commit 9462e4136c0a2100dc28b20cf9542e06790aa67e.
