OneDrive auto login after initial authorisation
<p>I want to be able login user automatically in my WPF C# app after he/she accepts it and login manually for the first time. Currently my code to login using prompt window works:</p>

<pre><code>try
{
    _msaAuthenticationProvider = new MsaAuthenticationProvider("XXXX",
        "https://login.live.com/oauth20_desktop.srf", new[] {"onedrive.readonly", "wl.signin", "wl.offline_access" });
    await _msaAuthenticationProvider.AuthenticateUserAsync();
    _oneDriveClient = new OneDriveClient("https://api.onedrive.com/v1.0", _msaAuthenticationProvider);

    Item item = await _oneDriveClient
        .Drive
        .Root
        .Request()
        .GetAsync();

    Print("Logged in as " + item.CreatedBy.User.DisplayName);
}
catch (Exception exc)
{
    PresentServiceException(exc);
}
</code></pre>

<p>Now the question is how do I save some info (tokens maybe?) and use them next time my app is launched to log in a specific user without showing that prompt window? I've read about <code>GetSilentlyAuthenticatedMicrosoftAccountClient</code> method on <code>OneDriveClient</code> but it seems not to be included in Microsoft.OneDrive.SDK 2.0.0 (all samples that use this and <code>OneDriveClientExtensions</code> reference to SDK in version 1.1.5). Do you have any idea how to accomplish that?</p>
