Speed O/R Mapping with LINQ to SQL: Figure A: Correct EntityType and EntitySet Names.
The EDM Designer doesn't singularize plural table names when assigning EntityType names. If you singularize default EntityType names manually, the designer renames corresponding EntitySets by adding a "Set" suffix to the singular EntityType name. Huagati Systems' DBML and EDMX Utility corrects this misstep automatically by removing "Set" and pluralizing the Entity Set name. The utility's renaming feature offers other optional corrections, such as applying proper case to EntitySet, EntityType, and property names as well as removing prefixes, suffixes, underscores or all three, from names.
