    <p>It seems that lazy loading does not work the same with code-first as it does with db-first:</p> <p>Consider:</p> <pre><code>public class Project { [Key] public long ProjectId { get; set; } [Required] [MaxLength(60)] public virtual string Name { get; set; } } </code></pre> <p>And:</p> <pre><code>public class TestCase { [Key] public long TestCaseId { get; set; } [Required] [ForeignKey("ProjectId")] public virtual Project Project { get; set; } public virtual long ProjectId { get; set; } } </code></pre> <p>In this DbContext:</p> <pre><code>public class TestDbContext : DbContext { public TestDbContext() : base("TestIckle") { } public DbSet&lt;Project&gt; Projects { get; set; } public DbSet&lt;TestCase&gt; TestCases { get; set; } } </code></pre> <p>When I try to to this in my code it does not work:</p> <pre><code> Console.WriteLine(_db.Configuration.LazyLoadingEnabled); //prints true TestDbContext _db = new TestDbContext(); var testcase = _db.TestCases.Create(); testcase.Project = _db.Projects.Find(7); //the following line outputs 0 with Code-First //the following line outputs 7 with DB-First Console.WriteLine(testcase.ProjectId); </code></pre> <p>Is a code-first model less capable than a db-first one? Seems odd that I would have assign the nav property and the pkey for it, which makes me think I have something configured wrong.</p> <p>Should the following ever work?</p> <pre><code>var x = _db.TestCases.Create(); x.ProjectId = 7; Console.WriteLine(x.Project.Name); //this never seems to work </code></pre> <p>Would be nice, seing as x knows which context it is attached too, I would have thought it could have handled this situation.</p> <p>Thanks.</p>

    1. COCan you please clean up your fourth example? I'm not sure where how you would be getting 0 or 7 from `testcase.Project`.

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).
