Using GroupShareKit in a Trados Studio Plugin

[pypae]

When trying to use GroupShareKit (installed via Nuget) in a Trados Studio Plugin, there is an error when loading the plugin:

Error Message

Cannot load the plug-in defined in '...'. 
The Plugin contains references to SDL assemblies that have not been validated for use with third-party plug-ins.

SDL Assembly Name	Version	Validation Error
Sdl.Core.Bcm.BcmModel	1.0.0.0	SDL assembly reference is not public
Sdl.TMService.Sdk	2.1.0.0	SDL assembly reference is not public

Background

We are trying to integrate terminology into our machine translation plugin. I.e. each translation request to our api includes all terms that need to be enforced in the requests segment.

We found no way to get the terms that are detected for each segment (either by MultiTerm or a custom Terminology Provider) in Trados Studio, using the SDK. That's why we tried to use GroupShareKit to directly get the terminology from the MultiTerm Server.

Are we forced to build our own client for the GroupShare REST API?
