This code sample is one of three referenced in the Azure AD sessions of the Microsoft Cloud Roadshow. Recordings of these sessions will be available shortly here. We recommned you watch one of these recordings to understand the purpose and goals of this code sample.

To-Do List Reimagined (tdlr;) is a new cloud service that allows users to store and manage a list of tasks. It integrates with Azure AD in order to provide enterprise features to its customers that have an existing Azure AD tenant. These features include:

• Discovery of accounts with an existing Azure AD tenant
• Signing up for the app with a work account
• One-click user authorization using consent & OAuth 2.0
• Signing into the app with a work account
• Sharing tasks between users in the same company using a "people picker".
• Outsourced user management to company admins

The full service consists of three different sample projects:

• The tdlr; web application, written as .NET 4.5 MVC app.
• The tdlr; iOS application, written as a cross-platform Xamarin app.
• The tdlr; admin web portal, written as a .NET 4.5 MVC app.

You'll first need to register an app in the Azure Management Portal so that your version of tdlr; can sign users in and get information from Azure AD. In order to do so, you will need an Azure Subscription. If you don't already have an Azure subscription, you can get a free subscription by signing up at http://azure.com. All of the Azure AD features used by this sample are available free of charge.

You'll also need an Azure Activce Directory tenant in which to register your application. Every Azure subscription has an associated tenant, which you are free to use. You may also wish to create an additional tenant, since the tdlr; app is 'multi-tenant' - it allows users from any organization to sign up & sign in. You'll want to create a few users in your tenant(s) for testing purposes - a guest user with a personal MSA account will not work for this sample.

1. Sign in to the Azure management portal.
2. Click on Active Directory in the left hand nav.
3. Click the directory tenant where you wish to register the sample application.
4. Click the Applications tab.
5. In the drawer, click Add.
6. Click "Add an application my organization is developing".
7. Enter a friendly name for the application, for example "TDLR;", select "Web Application and/or Web API", and click next.
8. For the sign-on URL, enter the base URL for the sample, which is by default https://localhost:44322/. NOTE: It is important, due to the way Azure AD matches URLs, to ensure there is a trailing slash on the end of this URL. If you don't include the trailing slash, you will receive an error when the application attempts to redeem an authorization code.
9. For the App ID URI, enter https://<your_tenant_name>/tdlr, replacing <your_tenant_name> with the name of your Azure AD tenant, like mytenant.onmicrosoft.com. Click OK to complete the registration.
10. While still in the Azure portal, click the Configure tab of your application.
11. Find the Client ID value and copy it aside, you will need this later when configuring your application.
12. Find "the application is multi-tenant" switch and flip it to yes.
13. Create a new key for the application. Save the configuration so you can view the key value. Save this aside for when you configure the project in Visual Studio.
14. In "Permissions to Other Applications", click the dropdown for "Delegated Permissions". Check the Read all users' basic profiles permission, and Save the configuration. Your app should now show two delegated permission.

Now you can download this repo as a zip or clone it to your local machine:

git clone https://github.com/azureadsamples/azureroadshow-web

In your local repo, open the TDLR.sln file. We recommned you use Visual Studio 2015, which will restore all necessary packages for you when you run the app for the first time.

To run the app, you'll need to enter the information from your app registration. In Visual Studio, open the web.config file in the root of the project and locate the <appSettings> section. Replace the following values with your own:

    <add key="ida:ClientId" value="[Enter your clientID from the Azure Management Portal, e.g. b1132c6b-fbf8-43b3-a9d8-329be1c87fcb]" />
    <add key="ida:AppKey" value="[Enter your key from the Azure Management Portal, e.g. TpNUr1CrYMP5bkvXKwmRKQvINuTp2nyp4kIzoabgZC0=]" />
    <add key="ida:Tenant" value="[Enter the name of the tenant where you registered your app, e.g. mytenant.onmicrosoft.com]" />
    <add key="ida:TaskApiResourceId" value="[Enter your App ID URI from the Azure Management Portal, e.g. https://mytenant.onmicrosoft.com/tdlr]" />

You can now run the tdlr; app and explore its functionality. Try signing up and signing in with your Azure AD users, creating tasks, and sharing them with other users. To understand the code behind the app, we recommend you watch on of the recorded Microsoft Cloud Roadshow sessions which will be available soon here. If you're already familiar with Azure AD, you may find the code comments instructive as well.
