When building a C# project in JetBrains Rider, I get this error:[NU1101] Unable to find package Xceed.Wpf.Toolkit.NET5. No packages exist with this id in source(s): Microsoft Visual Studio Offline Packages, nuget.org
I also get the same issue in Visual Studio and I can't figure out the solution. Any suggestions would be appreciated!
Tried some of the solutions in how to resolve "Unable to find package" nuget error, but they didn't work. Also tried Visual Studio Code - error NU1101: Unable to find package Microsoft.EntityFrameworkCore but to no avail
