Basically what I need is to retrieve the org url from a custom activity.
The reason is simple: merge it into some text and send an email, all from code.
I understand I can just pass it as a input parameter but the idea is to avoid the extra configuration in every install.
Also, I want to write something that will run on CRM Online.
I couldn't figure a way to instantiate the discovery service from a plugin so, is it even possible?
The OrganizationServiceProxy object also exposes the endpoit Uri which I could use but I couldn't instantiate it either, it appears that I can only get OrganizationService instead.
Any ideas?
Thanks in advance.
