The Api namespace (where e.g. Operation is found) doesn't have any company/product prefix, it's just Api. Would it be possible to adjust that? In [api.proto](https://github.com/dgraph-io/dgraph.net/blob/f54ee55a59a9f0d000ebf9d7e63e69cc817c1218/source/Dgraph/github.com/dgraph-io/dgo/protos/api.proto#L33) I see `option java_package = "io.dgraph";`. I assume just changing that to `option csharp_namespace = "io.dgraph";` will do the trick.
