I realize it comes with the installation media (in this case, a digital download, no CD). I have a feeling this has to do with my work place and how their licensing works (higher ed), but I cannot find an "sdk_dotnet" folder. Could someone tell me the location of it just so I can make sure I'm looking in the right place before contacting IT?
The SDK is available at https://my.esri.com/#/downloads
Click on the View Downloads button for ArcGIS for Desktop and you'll find the SDK download link in the Developers Tools section
I don't have access to MyEsri as that is not how universities typically let you download the software as they don't want you to have access to the entire installation media. It's all very locked down. But anyway, I contacted our IT department and they've got me setup with access. Thanks.
