LINQ to XML - XPath

Mon, 10 Nov 2008 17:24:02 GMT

LINQ to SQL may be on it's way out, but LINQ is no way out at all! And don't worry about LINQ to SQL, the ADO.NET Entity Framework is available and guess what it's awesome. Another good usage for LINQ is when you need to query an XML file. When working with LINQ to XML you may remember the old days when you used XPath. But don't worry anymore there is support for XPath on LINQ to XML. There are extension methods for LINQ to XML in the System.Xml.Xpath namespace! Read this blog post if you are interested in an example, and find out if there are any performance issues! Have fun reading!

What If I Don't Call Dispose() on my LINQ to SQL DataContext Object?

Thu, 21 Aug 2008 06:05:41 GMT

Steven Walther recently posted on the subject of disposing of DataContext objects and provided some interesting insight into what actually happens. From what he says it sounds like the DataContext object acts much like the SqlDataAdapter class. It opens the connection right before a query is executed and closes it immediately after. I don't want to steal Steven's thunder so check out his post on the subject (the last part of the article talks about the consequences.or lack of consequences.of not calling Dispose()).

Implementing the Repository Pattern with Linq-to-Sql

Fri, 06 Jun 2008 05:10:22 GMT

The Repository Pattern, according to Martin Fowler, provides a "layer of abstraction over the mapping layer where query construction code is concentrated", to "minimize duplicate query logic". In practice it is usually a collection of data access services, grouped in a similar way to the domain model classes. By accessing repositories via interfaces the repository pattern helps to break the dependency between the domain model and data access code. This is invaluable for unit testing because the domain model can be isolated.
