Microsoft Graph sample UWP app

This sample demonstrates how to use the Microsoft Graph .NET SDK to access data in Office 365 from UWP apps.

Prerequisites

To run the completed project in this folder, you need the following:

• Visual Studio installed on your development machine. If you do not have Visual Studio, visit the previous link for download options. (Note: This tutorial was written with Visual Studio 2022 version 17.3.5. The steps in this guide may work with other versions, but that has not been tested.)
• Either a personal Microsoft account with a mailbox on Outlook.com, or a Microsoft work or school account.

If you don't have a Microsoft account, there are a couple of options to get a free account:

• You can sign up for a new personal Microsoft account.
• You can sign up for the Microsoft 365 Developer Program to get a free Microsoft 365 subscription.

Register a native application with the Azure Active Directory admin center

1. Open a browser and navigate to the Azure Active Directory admin center and login using a personal account (aka: Microsoft Account) or Work or School Account.

2. Select Azure Active Directory in the left-hand navigation, then select App registrations under Manage.

3. Select New registration. On the Register an application page, set the values as follows.

   • Set Name to UWP Graph Sample.
   • Set Supported account types to Accounts in any organizational directory and personal Microsoft accounts.
   • Under Redirect URI, change the dropdown to Public client (mobile & desktop), and set the value to https://login.microsoftonline.com/common/oauth2/nativeclient.

4. Choose Register. On the UWP Graph Tutorial page, copy the value of the Application (client) ID and save it, you will need it in the next step.

Configure the sample

1. Rename the OAuth.resw.example file to OAuth.resw.
2. Open graph-tutorial.sln in Visual Studio.
3. Edit the OAuth.resw file in visual studio. Replace YOUR_APP_ID_HERE with the Application Id you got from the App Registration Portal.
4. In Solution Explorer, right-click the graph-tutorial solution and choose Restore NuGet Packages.

Run the sample

In Visual Studio, press F5 or choose Debug > Start Debugging.

Only works with 1 scope?

I got the sample working, but I wanted to change scopes to suite the app I am making. It works with Calendar.Read, but with no other scopes. How could I edit this sample so that It doesnt hang/ crash with other scopes?

Unhandled exception when login window is closed

I noticed that the demo solutions crash if I close the login window with the title bar close button. The exception message says:

"User canceled authentication. On an Android device, this could be due to the lack of capabilities, such as custom tabs, for the system browser. See https://aka.ms/msal-net-system-browsers for more information."

Please advice how to catch this exception? I already tried to subscribe to the MicrosoftGraphService.Instance.SignInFailed event but it doesn't fire in this situation.

Instructions appear to be out of date or inaccurate.

While trying to follow the instructions for registering the UWP app samples, I was not able to determine how I might add the redirect URI of: urn:ietf:wg:oauth:2.0:oob

Here are the steps I followed (visually):

When trying to set the redirect uri I see this:

What am I missing. How do I set the urn:ietf:wg:oauth:2.0:oob ???

To Reproduce
Steps to reproduce the behavior:
Issue 1:

4. After sign in again from sign in window, sign in window will not close. you need to close manually.
5. Create event & after creating it will sign out you from application
6. go to the Calendar page, it will ask for sign in again

Issue 2:
1. Open the application from visual studio
2. sign in into the application & go to the NewEvent Page
3. Try to search by name in Attendee Textbox(PeoplePicker control) : Use different name of user by which you are not sign in
4. After sign in again from sign in window, sign in window will hang.
5. go to the Calendar page, it will ask for sign in again

Expected behavior

1. After sign in into the application, user try to search user by their name in Attendee Textbox(PeoplePicker control), I should not ask for sign in again.
2. If user try to search by different user name, sign in window should not hang

Screenshots
After search user by different name than already sign in, the app just hangs indefinitely and a little blue flashing dot appears in the upper left hand corner. (See attached image for issue 2)

Exception trying to authenticate - Microsoft.Graph.Auth.AuthenticationException in System.Private.CoreLib.dll

Hi,

I tried running the sample with my own app Id and when I try to login, the window dissapears. In the debug output I see:

Exception thrown: 'Microsoft.Graph.Auth.AuthenticationException' in System.Private.CoreLib.dll

I tried using an MSA and an AAD account. It repros 100% for both accounts. Is there a workaround for this issue?

Cannot Log-in

I just did what was advised in the sample download, but after I type in my email address, I get:
invalid_request: The provided value for the input parameter 'redirect_uri' is not valid. The expected value is a URI which matches a redirect URI registered for this client application.

I did not change a single line of code, so any idea what went wrong?

Redirect URI not matching

WAB Authentication Failed

I'm getting a 'WAB Authentication Failed' message. I'm using my organization account to sign in. I registered my app using the Azure Portal and I'm wondering if that's the problem, but I want to understand why if that's the case.

Cannot sign-in

Using the Quick Start (using UWP), I did all of the steps (register app, got app id, went to the azure portal, added redirect, downloaded the zip, extracted). I loaded the solution and built it (using x64). When I run it there is no "sign-in" button. I watched the video under Build UWP apps with Microsoft Graph, he shows the same app with the button and he can sign in.

Am I missing something? Do I need to go through the tutorial to manually add the underlying code?

UPDATED I went through the step by step guide building the application from scratch and I have the same issue at the end of Step 1. All of the code copied correctly, it builds and executes ... but NO "sign in" button control.

I am building using VS2017 and Win10 Enterprise 1709 Build 16299.1451 ... is this an issue for this application?

PLEASE HELP

Oauth.resw not found

I downloaded and unzipped the project. It cannot find the file.
