If the user is signed into the app once then it should not ask user again for the sign in.

how to achieve that?

推荐答案

您可以将用户登录信息保存到IsolatedStorage.每个用户都有唯一的名称，我的意思是UserName中没有任何重复.因此，借助UserName，您可以将信息存储到IsolatedStorage.

例如

You can save the User Login information to IsolatedStorage. Each user has unique name, I mean there is no any duplication in UserName. So with the help of UserName you can store the information to IsolatedStorage.

For e.g.

public void SaveToStorage(string UserName)
{
    if (IsolatedStorageSettings.ApplicationSettings.Contains(UserName))
    {
        return;
    }
    IsolatedStorageSettings.ApplicationSettings["LoginStatus"] = UserName;
    IsolatedStorageSettings.ApplicationSettings.Save();
}

public bool GetFromStorage()
{
    if (IsolatedStorageSettings.ApplicationSettings.Contains(LoginStatus))
    {
        return true;                     // User is already Login
    }
    return false;
}

借助以上两个功能，您可以在Application Activated 或Launching event上检查此用户是否已经登录.

With the help of above two function you can check this on Application Activated or Launching event whether user is already login or not.
