Did a simple search/replace on the whole repo (except the RSSDP project) This reduces LOC and should improve performance (methods containing a throw statement don't get inlined) ``` if \((\w+) == null\) \s+\{ \s+throw new ArgumentNullException\((.*)\); \s+\} ``` ``` ArgumentNullException.ThrowIfNull($1); ```
