These days, there are very few packages with quicks like this, so we recommend just repackaging (either using the feature, or manually) a local copy for caching purposes.
Owin is one of these packages unfortunately. The latest (and only) package version is 1.0 (in some cases) and 1.0.0 in others. It's also over 8 years old, so it can't be helped.
ProGet 5.2 had better support for these versions quirks using a feature called "Legacy (Quirks) Feeds", but those feeds couldn't handle SemVer queries properly, since requests like 1.0 were ambiguous (should it return 1.0 or 1.0.0, both of which are valid versions, etc), so it was a big tradeoff. They were fully removed in ProGet 5.3.
). But it's still looking on track for early next year.
-- and a big thing we want to be improving in the next year, with both software and documentation changes.
