When EnableDiscriminatorValue is set to true all types end up with a required property of odata.type

My understanding is odata.type is only required in the case the type cannot be determined such as it being a type derived from the specified type.

When using EnableDiscriminatorValue = true I get correctly odata.type used as a discriminator when a type has a derived type.
I also get however for seemingly all types, odata.type included as a required property.

Assemblies affected

v1.1.0

Steps to reproduce

1. Create an odata model with no derived types.
2. Generate an Open API specification from the model with EnableDiscriminatorValue = true.

Expected result

I would only expect odata.type to be required in the case a type is a derived type.

Actual result

odata.type is set as required for all types.

If I use Open API connected services in Visual Studio with the specification to generate a client, the client will fail to deserialize responses missing the required property by default.

Additional detail

This can be worked around in most case.

Commencez par reproduire le problème avec un modèle OData qui ne comporte aucun type dérivé et pour lequel EnableDiscriminatorValue est défini sur true, puis examinez la spécification OpenAPI générée. Suivez la manière dont les métadonnées du discriminant deviennent une propriété obligatoire ; le travail est terminé lorsque odata.type n’est obligatoire que là où les types dérivés le rendent nécessaire, sans interrompre la désérialisation valide côté client.
