    <p>I'm experimenting with the latest EF 5 CF (in VS2010, not VS2012). I'm generally following the MSDN EF 5.0 Quickstart: Creating a Model with Code First...</p> <p>Rather than using a console app, my DbContext is in a Windows Service, which will eventually expose various data service methods by hosting a WCF Service (the client will be WPF MVVM)</p> <p>In the OnStart of the Windows Service, I invoke SetInitializer, and then do a simple query to trigger initialization:</p> <pre><code>// Start the Windows service. protected override void OnStart(string[] args) { Database.SetInitializer&lt;MediaLibraryContext&gt;(new MediaLibraryContextInitializer()); using (var context = new MediaLibraryContext()) { var firstMedia = (from m in context.Medias select m).FirstOrDefault(); } ... </code></pre> <p>And EF CF creates the database from the model and seeds it, as expected.</p> <p><strong>But when I stop/restart the Service, EF appears to delete the database and recreate it</strong> (or perhaps it's just dropping the tables and recreating them?). All post-initialization changes I've made to the database are gone, and only the "seed" data is present.</p> <p>I've worked with EF 4.1 and 4.3, but I've never seen this behavior. Any ideas where to look???</p> <p>DadCat</p> <p>EDIT: I found the problem just after posting this... the Quick start code has the database initialization strategy set to DropCreateDatabaseAlways.</p> <p>That's what I get for copy/pasting code without carefully looking at it!</p> <p>DC</p>

    1. COYour EDIT should be an answer (you can accept your own answer), or delete your question, nothing to answer here anymore, I think...

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.

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