I am using Microsoft Visual Studio Professional 2022 (64-bit) , Version 17.3.6.
I got the error message when I try to open "Manage Nuget packages for solution". I have restarted the Visual Studio, no help. I opened Nuget package manager -> Package manager settings. The package source was name: packageseouce, source: https://packageseouce. I changed it to name : nuget.org, source: https://api.nuget.org/v3/index.json. It still not working even after restart, rebuild.
My other solutions have no this problem.
Thank you for your help.
