Question
I'm migrating a project from EF6 to EF-Core. The Metadata API has changed significantly and I am unable to find a solution to this:
Under EF6 I could find the POCO Type from the Proxy Type using:
ObjectContext.GetObjectType(theEntity.GetType)
This, however, does not work under EF-Core (no ObjectContext class). I've searched and searched to no avail. Does anyone know how to get the POCO type from either the entity or the entity proxy type?
Accepted Answer
EF Core does not support the ObjectContext API. Further more, EF Core doesn't have proxy types.
You can get metadata about entity types from IModel.
using (var db = new MyDbContext())
{
// gets the metadata about all entity types
IEnumerable<IEntityType> entityTypes = db.Model.GetEntityTypes();
foreach (var entityType in entityTypes)
{
Type pocoType = entityType.ClrType;
}
}

There is no perfect way. You could for example check the namespace. If it's a proxy it'll
private Type Unproxy(Type type)
{
if(type.Namespace == "Castle.Proxies")
{
return type.BaseType;
}
return type;
}
