    <p>One day ago I started using Entity Framework CodeFirst in simple Windows Forms project (C#). I created two models:</p> <pre><code>[Table("SavesSet")] public partial class Saves { public Saves() { this.SkillsSet = new HashSet&lt;Skills&gt;(); } [Key] public int SaveID { get; set; } public string Player { get; set; } public int Age { get; set; } public int Money { get; set; } public virtual ICollection&lt;Skills&gt; SkillsSet { get; set; } } [Table("SkillsSet")] public partial class Skills { [Key] public int SkillID { get; set; } public string Name { get; set; } public int Value { get; set; } public int SavesSaveID { get; set; } public virtual Saves SavesSet { get; set; } } </code></pre> <p>Then I added one row into my database using Visual Studio Database Explorer (local database using SqlServerCe 3.5):</p> <p>SaveID = 1</p> <p>Player = "TEST"</p> <p>Age = 1</p> <p>Money = 1</p> <p>I also created form with ListView and wrote some code:</p> <pre><code>private SavesContext db = new SavesContext(); foreach (Saves s in db.SavesSet.ToList()) { ListViewItem l = new ListViewItem(); l.Name = s.SaveID.ToString(); l.Text = s.Player; ListViewSaves.Items.Add(l); } </code></pre> <p>But when I started program debugging ListView was empty. I set breakpoint, viewed local variables and saw that SavesSet count was 0.</p> <p>I added one row via code:</p> <pre><code>Saves s = new Saves(); s.Player = "TestName"; s.Age = 5110; s.Money = 200; db.SavesSet.Add(s); db.SaveChanges(); </code></pre> <p>And ListView displayed this one. But in my database there was nothing (and its size didn't change). I restarted Visual Studio - and my trouble was still actual: ListView shows item, but database was empty. I checked ConnectionString in App.Config and in VS Database Explorer - they were equal.</p> <p>So, my question is: How can I explore my real database and where does it stores?</p> <p><strong>Update.</strong></p> <p>My DbContext:</p> <pre><code> public SavesContext() : base("Saves") { } public DbSet&lt;Saves&gt; SavesSet { get; set; } public DbSet&lt;Skills&gt; SkillsSet { get; set; } </code></pre> <p>And my App.Config:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;configuration&gt; &lt;configSections&gt; &lt;/configSections&gt; &lt;connectionStrings&gt; &lt;add name="TextSim.Properties.Settings.Saves" connectionString="Data Source=C:\Documents and Settings\My\My Documents\visual studio 2010\Projects\TextSim\TextSim\Saves.sdf" providerName="System.Data.SqlServerCe.3.5" /&gt; &lt;/connectionStrings&gt; &lt;/configuration&gt; </code></pre>

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).
