Required Attribute

[MrWolfPST]

Add support for System.ComponentModel.DataAnnotations.RequiredAttribute besides Newtonsoft.Json.JsonRequiredAttribute

[justinyoo]

@MrWolfPST Thanks for the issue! Would you please elaborate?

[MrWolfPST]

I maked some additional tests and I must partial review the issue.
The only way I found for include a mandatory property in the required section of component is decorate property with [JsonProperty(Required = Required.Always)].
Instead if I use JsonRequired or Required attributes, property is not included in the required section.
Anyway the RequiredAttribute is not in the supportet attributes list

[justinyoo]

Here are the decorators we currently support:

• From Newtonsoft.Json
• From System.ComponentModel.DataAnnotations

It partially answers your question, though.

[MrWolfPST]

Yes I had read. My original request was for add support of RequiredAttribute of System.ComponentModel.DataAnnotations namespace. But seam that also JsonRequiredAttribute have some problem

[justinyoo]

Let me check.

JsonRequered not working in combination with JsonProperty with property name specified, as described in issue #227

I'm using the latest versions of this and .NET 6 and Azure Functions v4 and The Required Attribute does not seem to work at all.

@justinyoo System.ComponentModel.DataAnnotations.RequredAttribute does not work. Other things in the same namespace do. Is there a trick to this?
