This week the guys talk to Damien Guard, a developer working on LINQ to SQL and Entity Framework. After discussing data access for a while, they talk about the programming font Damien publishes, Envy Code R.

• Damien assures us that LINQ To SQL is not at all dead and talks about some of the new features in LINQ To SQL 4.
• Damien discusses the T4 templates in EF/VS2010 as well as the LINQ to SQL T4 templates he’s released on CodePlex as L2ST4.
• New features in EF 4 (LINQ operators, ObjectSet)
• Additional LINQ To SQL mocking with ITable<T>
• Some general discussion of query performance optimization in L2S and EF, including some enhancements in v4.
• Code-only configuration to enable fluent configuration for EF
• Kevin compares the code-only configuration to Fluent NHibernate
• K Scott asks about how code-only configuration would enable TDD with EFF
• Damien talks about the challenges of TDD and DDD when developing a framework
• Jon asks the “Should L2S be on CodePlex” question
• Damien mentions Matt Warren’s LINQ IQueryable Toolkit
• Jon asks about the experience and improvements to migration from L2S to EF
• K Scott asks about common L2S mistakes
• Jon asks about POCO support in EF
• Kevin bemoans the lack of support for refreshing a L2S model when your schema changes
• The talk shifts over to the programming font Damien designed, Envy Code R
• Damien explains the intricacies of TrueType, bitmap fonts and hinting
• Discussion of font editing software, from FontLab ($500) to FontForge (free, open source), and Microsoft Visual TrueType (free, weird license agreement which must be faxed in)

• Jon asks about the new typography features in Windows 7, including the new DirectWrite API
• Damien prefers Mac font rendering for quick glances, Windows for long use
