Description
The limitations of using a compiled model states that it cannot be used in combination with lazy loading proxies, but I have tested this, and in EF Core 10 it works without any error. Is this an old limitation which was valid in earlier versions?
In Program.cs:
builder.Services.AddDbContext<MyContext>(options => options .UseSqlServer(builder.Configuration.GetConnectionString(nameof(MyContext))) .UseModel(MyContextModel.Instance).UseLazyLoadingProxies());
The entities (simplified):
public partial class User { public int Id { get; set; } public int CompanyId { get; set; } public virtual Company Company { get; set; } }
public partial class Company { ... }
Some LINQ somewhere in code:
Context.User.Where(w => w.Id == 1).Select(s => s.Company).FirstOrDefault();
It fetches the Company and the objects show they have a LazyLoader attached to them.
