Huagati DBML/EDMX Tools is an add-in for Visual Studio 2008 and 2010, that adds functionality to the Linq2SQL and Entity Framework designers, adding options for comparing and synchronizing Linq-to-SQL designer diagrams with the database, for updating classes and properties generated using the Linq to SQL designer or Entity Framework designer to use .net naming conventions, to update documentation for L2S and EF-generated classes and properties with descriptions from the database, to generating incremental SQL-DDL corresponding to changes in L2S diagrams, and for comparing and updating Entity Framework v4 models in Visual Studio 2010 with differences across the database, SSDL, and CSDL boundaries.
