Check the User Whether Exist in Azure AD from WPF application : <p>I have a WPF application and its authentication is AzureAD. If any new user comes then first we will add that user in Azure AD and after that we will add the same user to our WPF application. While adding that user to WPF we need to verify that user is present in Azure</p>

<p>Steps
1. Network Admin creating a user in Azure AD
2. Our project Admin add that user to our client in Azure
3. Project Admin login to our WPF application using azure authentication and adding this user
4. At that time we need to recheck the new user is present in azureAD.</p>

<p>It means project admin login to WPF application using Azure authentication [His userid, ticket, clientid etc are available] and he trying to check a user present it Azure AD [New users name is available, but password will not know by this Admin]. </p>

<p>Please help me to write a c# code for solving this problem.</p>
