CredentialPicker.PickAsync未显示对话框

Question

我在app.xml.cs的OnLaunched方法中有以下代码，但对话框根本没有显示，有人可以建议：

CredentialPickerOptions credPickerOptions = new CredentialPickerOptions();
credPickerOptions.Message = Message.Text;
credPickerOptions.Caption = Caption.Text;
credPickerOptions.TargetName = Target.Text;
credPickerOptions.AlwaysDisplayDialog = (AlwaysShowDialog.IsChecked == true);
CredentialPickerOptions options = new CredentialPickerOptions()
{
    AuthenticationProtocol = AuthenticationProtocol.Basic,
    CredentialSaveOption = Windows.Security.Credentials.UI.CredentialSaveOption.Selected,
    CallerSavesCredential = true,
    Caption = "Basic Login",
    Message = "Please enter your credentials",
    TargetName = "."
};
CredentialPickerResults results = await CredentialPicker.PickAsync(options);

Answer 1

credentialPicker不会全屏打开，而是在页面顶部打开，因此您需要在打开第一页后打开它。如果您无法在凭证选择器之前打开应用程序的主页面，则可以创建一个包含启动画面图像的页面。
