Links from the Central Ohio .NET Developers Group May 2008 meeting:
The presentation was given by Jeff Hunsaker who works for Cardinal Solitions (thanks for the pizza) and is also one of the founders of the Central Ohio Application Lifecycle Management Group. Slides from the meeting are available on his blog.
The presentation was on Microsoft's (ADO.NET) Entity Framework. Jeff asked the audience about Object-Relational Mapping (ORM) and what tools they were using. The most common response was NHibernate. Jeff mentioned Subsonic and gave a brief demo. He also did a demo showing LINQ to SQL.
Also mentioned at the meeting was the upcoming Lansing - Day of .NET on June 21, 2008.
