Always need to sign in again and again to oneDrive. Session not saved?

[Txusete]

Hi,

I'm successfully connecting to OneDrive from a c# application on a consumer ClientType mode. However i always need to accept the "terms and conditions" when i start the application.
i'm using the following code (provided on the OneDriveApiBrowser):

private async Task SignIn(ClientType clientType)
{
Task authTask;

        if (clientType == ClientType.Consumer)
        {
            var msaAuthProvider = new MsaAuthenticationProvider(
                FormBrowser.MsaClientId,
                null,
                FormBrowser.MsaReturnUrl,
                FormBrowser.Scopes,
                null,
                new CredentialVault(FormBrowser.MsaClientId));
            this.oneDriveClient = new OneDriveClient("https://api.onedrive.com/v1.0", msaAuthProvider);
            authTask = msaAuthProvider.RestoreMostRecentFromCacheOrAuthenticateUserAsync();
        }
        else
        {
            var adalAuthProvider = new AdalAuthenticationProvider(
                FormBrowser.AadClientId,
                FormBrowser.AadReturnUrl);
            this.oneDriveClient = new OneDriveClient(FormBrowser.AadTargetUrl + "/_api/v2.0", adalAuthProvider);
            authTask = adalAuthProvider.AuthenticateUserAsync(FormBrowser.AadTargetUrl);
        }

        try
        {
            await authTask;
        }
        catch (ServiceException exception)
        {
            if (OAuthConstants.ErrorCodes.AuthenticationFailure == exception.Error.Code)
            {
                MessageBox.Show(
                    "Authentication failed",
                    "Authentication failed",
                    MessageBoxButtons.OK);

                this.oneDriveClient = null;
            }
            else
            {
                PresentServiceException(exception);
            }
        }

        this.clientType = clientType;

        try
        {
            await LoadFolderFromPath();

            UpdateConnectedStateUx(true);
        }
        catch (ServiceException exception)
        {
            PresentServiceException(exception);
            this.oneDriveClient = null;
        }
    }

I have been browsing all around the web and some people seem to have found a solution by using:
OneDriveClient.GetMicrosoftAccountClient(). thats also mentioned on the main page of this project , however the sample sources do not include that code anywhere. When i try to use that call on the project i got an error saying that OneDriveClient do not have a reference to GetMicrosoftAccountClient().

Is the sample not updated with the latests comments from the main page of the project?

Thanks!!!
