How nuget install decides when to download a new version of a package?

Question

My scenario is this:

1. Use nuget install without version to get the latest version of a package
2. Publish a new version of the package
3. Check with nuget list that the new version is indeed published
4. Run nuget install again.

What I noticed is that nuget install does not fetch the new version right away. It takes about an hour to see it.

So how does it work exactly?

Answer 1

Nuget caches all made requests in the http-cache (see "nuget locals" in the docs for reference). Objects (aka queries and their result) in this cache have an expiration of about 30minutes to 1 hour depending on the version of nuget.exe.

Use nuget locals http-cache -clear to clear this cache, then nuget should fetch the new versions without having to wait
