Heads up for anyone who attends Denver Visual Studio .NET User Group meetings.  At the next meeting, Chris Wallace will be giving a copy of my new book LINQ Programming/McGraw-Hill to someone who volunteers to do a review.  The only way to get this copy of LINQ Programming is to watch for the E-mail newsletter with the announcement.  Here's the URL where you can sign up (its free) and start receiving the user group newsletter:

 

 

I'll be at the meeting (1/26/2009), available to sign the book for whoever gets it.

LINQ Programming is shipping - I just received my copies from McGraw-Hill.

Here's a FAQ for using the ADO.NET Entity Framework/LINQ to Entities:

 

If you get the following error message when using LINQ to Entities:

 

Cannot convert lambda expression to type 'string' because it is not a delegate type

 

Check to see that you've added a using declaration for System.Linq at the top of your file.

Along with other C# open-source projects, Anoop Madhusudanan comments on LINQ to Twitter at http://amazedsaint.blogspot.com/2008/12/five-super-cool-open-source-c-projects.html:

 

"LINQ To Twitter - Good, really good. A LINQ provider for Twitter. Worth considering if you ever thought about writing a twitter client or twitter mining application. http://www.codeplex.com/LinqToTwitter".

 

As my own worst critic, there's more to do, but thanks for the compliment Anoop.
