Fixing the NuGet 401 Error Following Account Migration

Handling Account Migration Issues:

Problems with different tools and services are prevalent while moving a Microsoft account domain. This is especially true for developers who use JetBrains Rider and SourceTree, as issues with authentication can cause workflow disruptions.

In this instance, altering the account domain (e.g., from myName@myName.com to myName@notMyName.com) may result in login problems with SourceTree's Git Credential Manager and 401 Unauthorized failures during NuGet Restore in Rider. Here's how to deal with these issues.

Command	Description
Remove-Item	Deletes a file or directory; this is used to remove configurations and credentials that are cached.
nuget sources Add	Creates a new NuGet source and assigns credentials to it; this is necessary to reset access following an account migration.
git-credential-manager uninstall	To reset credentials, uninstall the Git Credential Manager.
git-credential-manager install	Make sure the Git Credential Manager is using the updated account credentials by reinstalling it.
cmdkey /delete	Removes credentials that have been saved from the Windows Credential Manager.
pkill -f rider	Terminates all active JetBrains Rider instances, making sure the software is terminated before deleting configurations.
rm -rf	Recursively and violently deletes folders and their contents; this is how Rider's configuration and cache directories are deleted.

Knowing How to Address 401 Unauthorized Errors

The given scripts deal with unique problems that come up after moving a Microsoft account domain, especially with SourceTree and JetBrains Rider. The first script clears cached configurations and credentials using PowerShell commands. The previous NuGet package cache and configuration files are removed using the Remove-Item command, and the NuGet source is then added again using the nuget sources Add command with the new account credentials. By doing this, you may avoid the 401 Unauthorized issue by making sure Rider attempts a NuGet Restore with the right, current credentials.

The second script deals with Git Credential Manager problems. Using git-credential-manager uninstall, it first removes the existing Git Credential Manager before reinstalling it using git-credential-manager install. Using git config, it sets up Git to utilize the new account, and cmdkey /delete is used to remove any previous credentials from Windows Credential Manager. Finally, the script initiates a new login prompt by attempting to clone a repository, ensuring that the user logs in with the new account credentials.

Resolving the 401 Unauthorized Error in NuGet Restore in Rider

How to Clear Cache Credentials Using PowerShell

# Remove cached credentials for the old account
Remove-Item -Path "$env:USERPROFILE\.nuget\packages" -Recurse -Force
Remove-Item -Path "$env:APPDATA\NuGet\NuGet.Config" -Force
# Re-add the NuGet source with the new account
nuget sources Add -Name "MyNuGetSource" -Source "https://myNuGetSource" -Username "myName@notMyName.com" -Password "myPassword"
# Verify the new source is added correctly
nuget sources List

Fixing Problems with Git Credential Manager Login

Configuring a New Account with Git Credential Manager

# Uninstall Git Credential Manager
git-credential-manager uninstall
# Reinstall Git Credential Manager
git-credential-manager install
# Configure Git to use the new account
git config --global credential.microsoft.visualstudio.com.username "myName@notMyName.com"
# Clear existing credentials from Windows Credential Manager
cmdkey /delete:LegacyGeneric:target=git:https://myCompany.visualstudio.com
# Try to clone or pull from the repository to trigger a new login prompt
git clone https://myCompany.visualstudio.com/DefaultCollection/_git/myRepo

Expunging the Cache and Rider Settings in JetBrains

Rider Configuration Reset with a Shell Script

#!/bin/bash
# Close JetBrains Rider if it's running
pkill -f rider
# Remove Rider configuration and cache directories
rm -rf ~/.config/JetBrains/Rider*
rm -rf ~/.cache/JetBrains/Rider*
rm -rf ~/.local/share/JetBrains/Rider*
# Restart Rider

Fixing Authentication Problems with Account Migration

When 401 Unauthorized issues arise following an account migration, one more thing to think about is how they may affect integrated development environments (IDEs) such as Visual Studio. Just like with JetBrains Rider, old or cached credentials may cause Visual Studio to fail when attempting to restore NuGet packages. It is important to make sure that Visual Studio is set up to use the new account credentials. NuGet.config should be updated, the NuGet cache should be cleared, and all package sources should have their configurations checked to make sure the new credentials are applied appropriately.

It's also crucial to make sure that the new credentials are included to any Continuous Integration/Continuous Deployment (CI/CD) pipelines. For instance, it's possible that Azure DevOps pipelines are still using outdated credentials that are kept in service connections. During automated builds and deploys, preventing authentication problems can be achieved by updating these service connections with the updated account data and refreshing any associated tokens.
