    text
    copied!<p>What I need to do is automap subclasses of my abstract page class. I need to find them in a list of assemblies that I get a runtime (at the initialization stage). I don't have any reference to the assemblies from the assembly of my mappings. </p> <p>My page class looks something like this:</p> <pre><code>public abstract class Page : EntityBase { public virtual int Id { get; protected set; } public virtual Page Page { get; set; } //Other properties } </code></pre> <p>My mappings looks like this:</p> <pre><code>var persistenceModel = new AutoPersistenceModel(); _assemblies.ForEach(x =&gt; persistenceModel.AddEntityAssembly(x)); persistenceModel.Setup(x =&gt; { x.SubclassStrategy = y =&gt; SubclassStrategy.Subclass; x.DiscriminatorColumn = y =&gt; "Type"; }) .IncludeBase(typeof(Page)) .OverrideAll(x =&gt; x.IgnoreProperties(y =&gt; typeof(Page) .IsAssignableFrom(y.ReflectedType) &amp;&amp; y.ReflectedType != typeof(Page))) .Where(y =&gt; typeof(EntityBase).IsAssignableFrom(y)); </code></pre> <p>_assemblies is a list of assemblies to search for mappable entities in. It contains the assembly of my page class as well as one or more other assemblies that all have a reference to the base assembly (the one with my page class).</p> <p>When I add a class that inherits from my page class to the same assembly as my page class all works fine and its mapped appropriately. But if I add one to one of the other assemblies that are loaded at runtime I get problems. I get this error:</p> <p>"Tried to add many-to-one 'Page' when already added."</p> <p>It finds the class but for some reason tries to map it as Page or something. But the page class is already mapped so I get that error. That is my guess. Does anyone know if I can work around this in any way? Or know a solution?</p>
