Previous versions load the InedoCore extension successfully from https://inedo.com/den/feed/download/inedox/InedoCore/1.0.6, but version 5.1.x does not load it. I failed to find any relevant logs as to why, and the extension list simply does not show it.
I have verified the extension location to be /var/proget/extensions, and if I download the extension from the Web UI, this is also where it ends up.
If I place a corrupt zip file in its location (i.e. /var/proget/extensions/InedoCore.upack), there is an error shown on the extensions page that it cannot unzip the .upack, so it seems the files are in the right place.
The same problem occurs with e.g. the Azure plugin.
Is there any change in 5.1 that could affect how extensions are loaded?
