LoginDialog for easy Live SDK OAuth

Thu, 06 Dec 2018 00:00:00 +0000

Almost every developer I speak with agrees that getting a nicely working OAuth flow can be difficult. After much trial and error, I’ve built a UWP ContentDialog that makes this easy and has built-in refresh token support.

Using the LoginDialog

This is very simple to use, when the app launches, instantiate the dialog by passing your Live SDK ClientID and let the LoginDialog do the heavy lifting:

// Pass your app's OAuth ClientId (sometimes called an AppId)
var loginDialog = new LoginDialog("YourAppClientId");

// *** Perform login **** //
// Case 1 - If the user was previously signed in, there is a refresh_token stored and no user-entered credentials are needed.
// Case 2 - If the access token fails, or if it's the first sign-in, the user will see a popup to enter credentials.
await loginDialog.SignInAsync();

if(!string.IsNullOrEmpty(loginDialog.Authentication))
{
 // This will be the access token you can use for API calls.
 var accessToken = loginDialog.Authentication;

 // Make your API calls with the accessToken, for example:
 var user = await apiService.GetUserProfileAsync(accessToken);
}

This works just like a MessageDialog, but instead will show a WebView for the user to sign in, or automatically sign them in silently if they were previously logged in.
