Body
I have the following class definition: <pre><code>public abstract class ControllerBase<T, V> : Controller where T : EntityBase<T> where V : GenericRepository<T> </code></pre> Then later on in the class I have the following code: <pre><code>private V _repo; ... _repo = (V)Activator.CreateInstance(typeof(V), _dbC, _c); </code></pre> This compiles just fine. I then have a class with the following definition: <pre><code>public class SecurityRoleController : ControllerBase<SecurityRole, GenericRepository<SecurityRole>> </code></pre> That also compiles just fine. However, when I try to hit /SecurityRole in my browser, I get an exception that <code>Constructor on type GenericRepository'1 not found</code>. (Note that it's actually a backtick in the exception but that breaks SO formatting.) This is despite the fact that <code>GenericRepository<T></code> has a public constructor that works just fine when I try to directly create an instance of the class. Anyone know how I can properly construct a generic instance of the class? TIA, Benjy EDIT: Constructor of <code>GenericRepository</code>: <pre><code>public GenericRepository(DbContext dbContext, Context c, string[] includes = null) { _dbContext = dbContext; _c = c; if (includes != null) { _includes = includes; } return; } </code></pre> And, the types of <code>_dbC</code> and <code>_c</code> are of <code>DbContext</code> and <code>Context</code>, the types that the <code>GenericRepository</code> requires in its constructor - and yes, I got these from <code>.GetType().FullName</code>. Any thoughts?

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.
