We have an ArcGIS Server license. Can the ArcObjects SDK for Microsoft .NET be installed on more than one developer's computer? If this is not the right place to ask this question, can you tell me who to ask?
In your case you have to consume a server license when you start to use any of their ArcObjects code. If you have multiple developers building code targeted for one server then I think you need to look at getting EDN licenses. DG
