When working with different Application Feeds in Azure (Artifacts), I was puzzled as to why my Visual Studio solution could no longer find the NuGet packages.
The solution is to connect the feed to your solution, which must be done each time you change.
Steps
Right click VS solution -> Manage NuGet Packages for Solution -> change Package source
If package source is not there:
Azure Artifacts -> Connect to Feed -> Visual Studio
