* dotnet format style --severity info Some changes were manually reverted. * Restore a few unused methods and variables * Address most dotnet format whitespace warnings * Apply dotnet format whitespace formatting A few of them have been manually reverted and the corresponding warning was silenced * Add previously silenced warnings back I have no clue how these disappeared * Add comments to disabled warnings * Simplify properties and array initialization, Use const when possible, Remove trailing commas * Address IDE0251 warnings * Revert "Simplify properties and array initialization, Use const when possible, Remove trailing commas" This reverts commit 9462e4136c0a2100dc28b20cf9542e06790aa67e. * dotnet format whitespace after rebase * First dotnet format pass
