How can I get the entity attributes metadata list?

Question

Dynamics 365 v8.2.2.

Why attributesMetadata is null? How can I get the entity attributes metadata list?

{
    var req = new RetrieveEntityRequest {
        LogicalName = "opportunity",
        RetrieveAsIfPublished = true,
    };

    var resp = srv.Execute(req) as RetrieveEntityResponse;
    var entityMetadata = resp.EntityMetadata;
    var attributesMetadata = entityMetadata.Attributes; // null
}

You need to set EntityFilters in request like:

EntityFilters = EntityFilters.All

Or

EntityFilters = EntityFilters.Attributes

The complete snippet as follows:

RetrieveEntityRequest retrieveEntityRequest = new RetrieveEntityRequest
{
    EntityFilters = EntityFilters.Attributes,
    LogicalName = "opportunity"
};
RetrieveEntityResponse retrieveOpptyEntityResponse(RetrieveEntityResponse)service.Execute(retrieveEntityRequest);
EntityMetadata opptyEntity = retrieveOpptyEntityResponse.EntityMetadata;

By default, EntityFilters.Default only entity information will be retrieved, that’s why you have empty attribute list.
