TryValidateModel is not working for nested attributes

[ThumNet]

Hi Shibayan,

When using TryValidateModel method DataAnnotations attributes (for example [Required]) on nested objects/properties are not validated.

public class SampleModel
{
    [Required]
    public string Name { get; set; }

    public string[] Array { get; set; }

    public NestedModel Nested { get; set; }
}

public class NestedModel
{
    [Required]
    public string Name { get; set; }
}

When posting the SampleModel and omitting the Name property, TryValidateModel returns true and not false as expected.

Tried with:

{
    "name": "test",
    "nested":{       
    }
}

and also with:

{
    "name": "test"
}

This is what I expected:

Is this something you are aware of or a bug?

Ps I found a fix for the behavior described above, and if you are interested I can provide a PR.

Thanks for the report. This issue has been fixed in v1.1.1.
Since the validation process is now common to ASP.NET Core, the behavior will be more consistent.

Wow, what a quick fix :)

Thank you!
