Since LINQ was added to the .Net Community as a new wonderful new player, more and more solutions I have seen returns the IQueryable<T> from the Data Access Layer. One reason is to easy create different kind of queries in an easy way and execute them. Some developers use the IQueryable<T> interface to create a light weight interface ...

First, the things I liked the most…LINQ To SQL is PI (ie, Persistence Ignorant) which is great (at least, that is what I think). This means that your classes won’t have to inherit from any specific class or implement some ...

I’ve written a few posts about LINQ to SQL and am generally a big fan of the technology (even with its weaknesses) since it’s very productive.  After creating a custom DataContext object using the LINQ to SQL designer (or one created by hand) I always ensure that the object is wrapped in a “using” statement so that the Dispose() method is ...

.NET 3.5’s LINQ to SQL functionality provides a great way to write data access layer code that automatically handles mapping relational data to object properties.  Although I generally prefer to use stored procedures when performing insert, update or delete operations against a database (see my previous post on this), I still use LINQ to SQL ...

I was looking for a quick and easy solution to export data from SQL into an Excel format from within my ASP.NET application.
