User cancelled dialog.

Error message

User cancelled dialog.

What it means

SelectAccountCommand's ExecuteAsync shows an account-selection dialog after listing stored GitHub accounts. If the window is closed without picking an account (WindowResult false), it throws a plain Exception with this message because no account can be written to the result.

Solutions

1. Re-run the command and explicitly select an account, then confirm the dialog.
2. Remove unwanted stored accounts ('git-credential-manager github logout') so the picker is not needed.
3. Specify the account/username up front in the git URL (e.g. https://username@github.com/owner/repo.git) to bypass the picker.
4. Catch the exception in tooling and treat it as 'no account chosen'.

var accounts = run("git-credential-manager github list");
if (accounts.Split('\n', StringSplitOptions.RemoveEmptyEntries).Length > 1)
{
    // multiple accounts: embed the desired user in the remote URL to skip the picker
}

try
{
    await selectAccountCommand.ExecuteAsync(input, output);
}
catch (Exception ex) when (ex.Message == "User cancelled dialog.")
{
    // no account chosen; fall back to username-in-URL or re-prompt
}

When it happens

Trigger: Running the select-account command when multiple GitHub accounts are stored and the user cancels or closes the account picker dialog without selecting one.

Common situations: Users with several GitHub accounts dismissing the picker; automation that cannot render the dialog; users wanting to add a new account but cancelling instead.
