DerivesFrom not work on 7.9.0

[premiaware]

I have this code on

public static void Register(HttpConfiguration config)
{
......
            builderWeb.EntitySet<Regioni>("Regioni");
            builderWeb.EntitySet<Uffici>("Uffici");
            builderWeb.EntitySet<UfficiExt>("UfficiExt");
            builderWeb.EntityType<UfficiExt>().DerivesFrom<Uffici>();
......
}

On the controller i have this method

 [HttpGet]
        public async Task<IHttpActionResult> Ufficio([FromODataUri] Guid key)
        {
            UfficiExt ufficioExt = new UfficiExt();
........
........

            return Ok<UfficiExt>(ufficioExt);
        }

With version 7.8.3 all working Ok!!!

With version 7.9.0 the error is:

Hi,
It would be really great if you can please share a repro. Also can you please share the model (probably as a part of repro) and the request you are making which causes the exception
thanks

@premiaware , Will be really great if you can please provide the same (repro and request) and we can fix it
Thanks

@premiaware This line in the stack trace piqued my interest:

'FHServices.Models.UfficiExt' does not inherit from and is not a base type of 'FHServices.Models.LandingPageImmobili'

Why does it refer to FHServices.Models.LandingPageImmobili?

The sample code you shared above suggests the target framework for your application is NET Framework 4.*
AFAIK, if you installed the latest Microsoft.AspNet.OData nuget package (7.5.8) in your project, the version of ODL library that is installed is 7.8.2. Did you manually update the ODL library package on your project to 7.9.0?

I tried that and everything works fine with the following application code:
Packages:

• Microsoft.AspNet.OData 7.5.8
• Microsoft.OData.Core 7.9.0
• Microsoft.OData.Edm 7.9.0
• Microsoft.Spatial 7.9.0

// Models
public class Animal
{
    public int Id { get; set; }
    public string Name { get; set; }
}

public class Dog : Animal
{
    public string Breed { get; set; }
}

// Service configuration
public static void Register(HttpConfiguration config)
{
    var modelBuilder = new ODataConventionModelBuilder();
    modelBuilder.EntitySet<Animal>("Animal");
    modelBuilder.EntitySet<Dog>("Dogs");
    modelBuilder.EntityType<Dog>().DerivesFrom<Animal>();

    config.MapODataServiceRoute("odata", "odata", modelBuilder.GetEdmModel());
    config.Select().Filter().Expand().OrderBy().Count().MaxTop(null);
    config.EnsureInitialized();
}

// Controller
public class DogsController : ODataController
{
    private readonly IList<Dog> dogs = new List<Dog>
    {
        new Dog { Id = 1, Name = "Butch", Breed = "Pitbull" }
    };

    public IHttpActionResult Get([FromODataUri] int key)
    {
        var dog = dogs.SingleOrDefault(d => d.Id.Equals(key));

        if (dog == null)
        {
            return NotFound();
        }

        return Ok<Dog>(dog);
    }
}

Request:

http://localhost/odata/Dogs(1)

Response

{"@odata.context":"http://localhost/odata/$metadata#Dogs/$entity","Id":1,"Name":"Butch","Breed":"Pitbull"}

Why does it refer to FHServices.Models.LandingPageImmobili?
I don't Know! i have try with sample but it working, in my production project not work.

my class is

public class TelefonoDescrittivo
{
public string Etichetta { get; set; }
public string Numero { get; set; }
}

public partial class UfficiExt : Uffici
{
    public List<TelefonoDescrittivo> Telefoni { get; set; }
}

Working only i change the
public List Telefoni { get; set; } ---> public List Telefoni { get; set; }

or i declare TelefonoDescrittivo With Entity.

Now i have downgrade the version and working well.

Thanks @premiaware , Will be great if you can share a repro, your model and the request you are making so that we can get the exact scenario

[premiaware]

I have update my odata project to .net 6 using odata 8.0.12 and the previous issue return.
this is the thread https://github.com/OData/AspNetCoreOData/issues/760
Using odata 7.12.5 all is ok!!!
for my point of view this is a issue with bounded function controller that return data type that containt complex type. if change the complex type
public List<TelefonoDescrittivo> Telefoni { get; set; }

to
public List<string> Telefoni { get; set; }

all working well
