Hello @Francis Fiore thanks for reaching out.
Schemas and schemas groups are separate objects within the namespace and hence those are not tied to entities (event hubs within the event hub namespace).
You might be having a separate schema group per entity, in which case you can retrieve all the schemas for a given schema group, few examples below on how to achieve that:
- Using the Get Schemas REST API
- Using the SDK currently there is not a method to retrieve all schemas for a given a group, however, if this what you are looking for, I can reach out to the SDK internally to check on whether there are plans to implement this soon, in the meantime using the REST API would be the way to go.
