EF Code First, how to reflect on model

In EF code first, one specifies field properties and relationships using the fluent interface. This builds up a model. Is it possible to get a reference to this model, and reflect on it? I want to be able to retrieve for a given field, if it is required, what its datatype is, what length, etc...

You need to access the MetadataWorkspace. The API is pretty cryptic. You may want to replace DataSpace.CSpace with DataSpace.SSpace to get the database metadata.

public class MyContext : DbContext
{

    public void Test()
    {            
        var objectContext = ((IObjectContextAdapter)this).ObjectContext;

        var mdw = objectContext.MetadataWorkspace;

        var items = mdw.GetItems<EntityType>(DataSpace.CSpace);
        foreach (var i in items)
        {
            foreach (var member in i.Members)
            {
                var prop = member as EdmProperty;
                if (prop != null)
                {

                }
            }
        }
 }
