    <p>I am currently reading up on persisting objects in .net. As such I cannot offer a best practice, but maybe my insights can bring you some benefit. Up until a few months ago I have always used handcoded queries, a bad habit from my ASP.classic days.</p> <p><strong>Linq2SQL</strong> - Very lightweight and easy to get up to speed. I love the strongly typed querying possibilities and the fact that the SQL is not executed at once. Instead it is executed when your query is ready (all the filters applied) thus you can split the data access from the filtering of the data. Also Linq2SQL lets me use domain objects that are separate from the data objects which are dynamically generated. I have not tried Linq2SQL on a larger project but so far it seems promising. Oh it only supports MS SQL which is a shame.</p> <p><strong>Entity Framework</strong> - I played around with it a little bit and did not like it. It seems to want to do everything for me and it does not work well with stored procedures. EF supports Linq2Entities which again allows strongly typed queries. I think it is limited to MS SQL but I could be wrong.</p> <p><strong>SubSonic 3.0 (Alpha)</strong> - This is a newer version of SubSonic which supports Linq. The cool thing about SubSonic is that it is based on template files (T4 templates, written in C#) which you can easily modify. Thus if you want the auto-generated code to look different you just change it :). I have only tried a preview so far but will look at the Alpha today. Take a look here <a href="http://blog.wekeroad.com/blog/subsonic-3-alpha-updated/" rel="nofollow noreferrer">SubSonic 3 Alpha</a>. Supports MS SQL but will support Oracle, MySql etc. soon.</p> <p>So far my conclusion is to use Linq2SQL until SubSonic is ready and then switch to that since SubSonics templates allows much more customization.</p>

    1. CORe: EF being limited to MS SQL - out of the box - yes, but there are 3rd party partners developing providers for other RDBMS. So for example if you want ORACLE then a company called DevArt has both EF provider for ORACLE and also a LINQ-to-ORACLE implementation.

Querying!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
