I did an upgrade of CRM 2013 to CRM 365 9.0.

I am calling an external Web Service (.svc) (connected service) from my d365 9.0 plugin (.net 4.6.2).   Getting error from service that calls from partial trust caller cannot be made.

This call works fine in crm 2013 and plugins run in full trust mode but in d365 plugins run in partial trust even after isolation mode is None.

Is there a way we can do a configuration change in d365 registry settings or any other setings to make plugins run in full trust?
