    copied!<p>I am getting into the Entity Framework, but I am unsure if I am missing a critical point in the code-first approach.</p> <p>I am using a generic repository pattern based on the code from <a href="https://genericunitofworkandrepositories.codeplex.com/" rel="noreferrer">https://genericunitofworkandrepositories.codeplex.com/</a> and have created my entities.</p> <p>But when I try to access or modify the entity I run into the following:</p> <blockquote> <p>System.InvalidOperationException: The entity type Estate is not part of the model for the current context.</p> </blockquote> <p>It happens when I am trying to access it from my repository:</p> <pre><code>public virtual void Insert(TEntity entity) { ((IObjectState)entity).ObjectState = ObjectState.Added; _dbSet.Attach(entity); // &lt;-- The error occurs here _context.SyncObjectState(entity); } </code></pre> <p>The database (./SQLEXPRESS) is created just fine, but the entities (tables) is just not created on startup. </p> <p>I am wondering if I need to explicit set the mapping of the entities? Is EF not able to this by its own? </p> <p>My Entity is:</p> <pre><code>public class Estate : EntityBase { public int EstateId { get; set; } public string Name { get; set; } } </code></pre> <p>My context is as so:</p> <pre><code>public partial class DimensionWebDbContext : DbContextBase // DbContextBase inherits DbContext { public DimensionWebDbContext() : base("DimensionWebContext") { Database.SetInitializer&lt;DimensionWebDbContext&gt;(new CreateDatabaseIfNotExists&lt;DimensionWebDbContext&gt;()); Configuration.ProxyCreationEnabled = false; } public new IDbSet&lt;T&gt; Set&lt;T&gt;() where T : class { return base.Set&lt;T&gt;(); } } </code></pre> <p>Is there any specific reason why this error occurs? I have tried enable migrations and enable automatic migrations without any help either.</p>
