13 hours, 20 minutes ago trycatchfail.com — I'm a huge fan of ActiveRecord (and of all things Castle), but I like the fact that LINQ makes it very easy to do ad-hoc queries with a compile-time safety net. If you follow the steps below, you can build your own LINQ provider for ActiveRecord and get the syntactical sugar of language-integrated query with the simplicity of ActiveRecord. read more...

6 days, 20 hours ago codeforeternity.com — We can use the ElementAt extension method of LINQ to return the element at a specified index (zero based) in a sequence. However the ElementAt extension method would throw the System.ArguementOutOfRangeException when the specified index is a negative value or not less than the size of the sequence. In such a scenario, we can use the ElementAtOrDefault extenion method which would return the default value of a type instead of throwing the System.ArguementOutOfRangeException.

In this tutorial I will show you how to use LINQ to read such data. By the end of tutorial you will appreciate how easy and logical it is to use LINQ for reading data from delimited text files. read more...

8 days, 10 hours ago blog.domaindotnet.com — Undocumented Linq! .NET 3.5 SP1 Gold Forgot to Mention these Critical Changes that might Break your Code
BREAKING CHANGE: Cast<T> Behavior
Also, a new implementation recognizes queries that apply Where and/or Select to arrays or List<T> and fold pipelines of multiple enumerable objects into single specialized enumerables.
According to Dinesh Kulkari at Microsoft this enhancement: "….produces substantial improvement in base overhead of common LINQ to Objects queries (at times 30+%)."
