Package is not found in the following primary source

问题

I have a build pipeline set up to create Nuget packages and publish them to a feed in artifacts.

I was able to use the feed successfully.

However when I ran the pipeline again, causing the packages to publish again I am not able to update the consuming project successfully.

Even though I can see the correct new version number in the Package Manager (Visual Studio -> Tools-> Nuget Package Manager -> Manage Nuget Packages for solution)

When I click install I get an error

Package '<mypackagename with version number>' is not found in the following primary source

<correct feed nuget/v3/index.json> Please verify all your online package sources are available (OR) package id, version are specified correctly.

This is caused by caching. If you don't want to wait like the above answer suggested, just clear Nuget caches by going to Tools -> Options -> Nuget -> General and click on the "Clear All Nuget Cache(s)" button.

I waited another 5 minutes and the problem went away. Maybe the version shows before the publishing is complete.

You have to check your package source I think the default is

Microsoft Visual Studio Offline Packages 

So, you can change that to "All".
