To register the App11641655 app to Azure Active Directory (Azure AD) with the sign-on URLs of https://app.contoso.com, you can follow the below steps:

1. Sign in to the Azure portal using your credentials.
2. In the Azure portal menu, select "Azure Active Directory" from the left-hand side menu.
3. In the Azure Active Directory page, select "App registrations" from the left-hand side menu.
4. In the App registrations page, select "New registration".
5. In the "Register an application" page, provide a name for your application, for example, "App11641655".
6. Under "Supported account types", select "Accounts in any organizational directory (Any Azure AD directory - Multitenant)" or "Accounts in this organizational directory only (Single tenant)" as per your requirement.
7. In the "Redirect URI" section, add the sign-on URLs of https://app.contoso.com.
8. Click on the "Register" button to create the registration for the app.

After completing these steps, you will be redirected to the app's overview page, where you can get the application (client) ID and the tenant ID, which you may need to configure your app. You can also assign users or groups to the app and set permissions to control their access to the app.

Note: If you want to enable your app to access APIs or web services in Azure, you may need to create a client secret for your app. To do this, select "Certificates & secrets" from the app's overview page, and then click on "New client secret". Provide a description, set an expiration date, and click on the "Add" button to create the client secret.
