You must use the WebAuthenticationBroker class to manage and provide authentication across all services. The app must support single sign-on (SSO).
You need to implement an authentication strategy for the app.
Which five actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Answer :
Explanation:
Box 1:
Box 2:
Box 3:
Box 4:
Box 5:
Note:
* (Step 1-2) The web authentication broker is designed to assist you with single sign-on scenarios by emulating a fully web-based experienced. You provide the broker with a starting URL. This URL typically contains information such as special application codes and passwords used to verify your apps identity with the provider and a redirect URL the provider should send the user to when they are authenticated. You also provide the broker with an ending URL.
*(step 3-4) Example:
WebAuthenticationResult result = await WebAuthenticationBroker.AuthenticateAsync(
WebAuthenticationOptions.None,
startUri,
endUri);
* Step 5:
The result will return a response status (successful, an HTTP error, or the user canceled) and the contents of the final redirect.
The first parameter is the token you can use for further access, and the second is when the token will expire. Use this to store the token and reuse it without having to request a new one each time. if (result.ResponseStatus == WebAuthenticationStatus.Success)
{
** Partial example:
private void OutputToken(String TokenUri)
{
Page outputFrame = (Page)rootPage.OutputFrame.Content;
TextBox FacebookReturnedToken = outputFrame.FindName("FacebookReturnedToken") as TextBox;
FacebookReturnedToken.Text = TokenUri;
}
try
{
String FacebookURL = "https://www.facebook.com/dialog/oauth?client_id=" +
FacebookClientID.Text + "&redirect_uri=" +
Uri.EscapeUriString(FacebookCallbackUrl.Text) +
"&scope=read_stream&display=popup&response_type=token";
System.Uri StartUri = new Uri(FacebookURL);
System.Uri EndUri = new Uri(FacebookCallbackUrl.Text);
WebAuthenticationResult WebAuthenticationResult = await
WebAuthenticationBroker.AuthenticateAsync(
WebAuthenticationOptions.None,
StartUri,
EndUri);
if (WebAuthenticationResult.ResponseStatus == WebAuthenticationStatus.Success)
