I have often run into issues with references to the internal class System.Web.SR so I extracted it and corrected the references, then made everything public. It is called PSR and you can find it here: PSR.zip 

*NOTE: This has not yet been tested. Several people have expressed interest in it and I wanted to throw it out there ASAP. Let me know how it works out. I will be testing it at the end of the Delete Verb portion of the current project since there are several references to it therein.
