Visual Studio 2019在调试后自动删除了nuget包

Question

Every time I add any nuget package to my .net core application, it stays for a bit but it seems like after I start a debug and end it, the nuget package removed automatically from Visual studio project.

Is any thing changes in visual studio 2019?

Answer 1

After searching on internet I found solution on this developer community Website.

1. Close VS2019
2. Delete the ".vs" folder
3. Open VS2019, add the NuGet package
4. Save all

I suspect "Save all" after adding a NuGet package might be key here.

Answer 2

You should see: In the NuGet.Config file, DisabledPackageSources tag shows you the sources which are currently disabled, so if you want to make them be active, add the sources under the ActivePackageSource. Anyway, since it works well now after you edit the DisabledPackageSources, at least, we make sure that it would be related to the NuGet.Config file.
