Visual Studio 2017 only has offline Nuget Packages for .NET Core 2.x. How to get online packages?

Question

I want to get NuGet Packages from Nuget online, but Visual Studio is only giving me 'Microsoft Visual Studio Offline Packages' as an option.

I have tried adding another package source using the following URLS:

• https://www.nuget.org
• https://packages/nuget.org

and a few others, but I keep getting the following error(s):

[Package source] Unable to load the service index for source http://packagesource. An error occurred while sending the request. The remote name could not be resolved: 'packagesource' [Nuget Online] The V2 feed at 'https://www.nuget.org/Search()?$filter=IsAbsoluteLatestVersion&searchTerm=''&targetFramework=''&includePrerelease=true&$skip=0&$top=26&semVerLevel=2.0.0' returned an unexpected status code '404 Not Found'.

How can I get online packages for .NET Core?

Solution

I think the answer is:

1. Right click on the project and choose Manage NuGet packages.

2. Click on the settings cog in the top right corner of the Nuget packages tab.

3. In the settings dialog (as shown in the screenshot in the question), click on the + button.
4. Give the new source a name and a source of https://api.nuget.org/v3/index.json.

This appears to work for me

This should be default behaviour anyway, you must have removed your package source manually somehow.

And you should removed that other one you have in the list, it's nonsense.

@DavidG right, it should be the default behavior. Fresh install of VS2017 CE here, only offline package source is available.

"Package source" and http://packagesource are simply the default values that are prepopulated when you click to add a new source (the big green plus sign on the dialog)

Where did you find the https://api.nuget.org/v3/index.json URL? I couldnt find it anywhere in the documentation on nuget.org OR microsoft.

Thank you so much for this. I finally can make progress

Thanks! This worked, no idea why did they turn it off by default.

Fresh install of VS2019: same broken behaviour. Had to also manually add https://api.nuget.org/v3/index.json
