* dotnet format style --severity info Some changes were manually reverted. * dotnet format analyzers --serverity info Some changes have been minimally adapted. * Restore a few unused methods and variables * Fix new dotnet-format issues after rebase * Address review comments * 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 * Format if-blocks correctly * Run dotnet format after rebase and remove unused usings - analyzers - style - whitespace * Add comments to disabled warnings * Simplify properties and array initialization, Use const when possible, Remove trailing commas * cpu tests: Disable CA2211 for CodeBaseAddress and DataBaseAddress * Revert "Simplify properties and array initialization, Use const when possible, Remove trailing commas" This reverts commit 9462e4136c0a2100dc28b20cf9542e06790aa67e. * dotnet format whitespace after rebase * Apply suggestions from code review Co-authored-by: Ac_K <Acoustik666@gmail.com> * First dotnet format pass * Fix naming rule violations * Remove naming rule violation exceptions * Fix comment style * Use targeted new * Remove redundant code * Remove comment alignment * Remove naming rule exceptions * Add trailing commas * Use nameof expression * Reformat to add remaining trailing commas --------- Co-authored-by: Ac_K <Acoustik666@gmail.com>
