How to get dbsets metadata from EF CodeFirst DbContext?

Question

How do you programatically get the metadata for the dbset classes from an EF CodeFirst dbcontext? This is to loop through for code generation purposes.

After some additional research, I think I found an answer. Basically, you have to drop down into the ObjectContext, the original EF context that DbContext is a wrapper for, and use the MetadataWorkspace information below.

Please add another answer if there is a direct way to get this directly from the DbContext as it would be more intuitive and preferable if there is one.

using System.Data.Metadata.Edm;
using System.Data.Objects;
using System.Data.Entity.Infrastructure;

...

using (dbcontext context = new TestContext())
{
   ObjectContext objContext = ((IObjectContextAdapter)context).ObjectContext;
   MetadataWorkspace workspace = objContext.MetadataWorkspace;
   IEnumerable<EntityType> tables = workspace.GetItems<EntityType>(DataSpace.SSpace);

}

Thanks, Will

I figured out how to reference the Entities in the DbContext but I am still uncertain how to get that reference in the T4 template that I am using for the code generation. Any ideas? I will probably post another question on that issue.
