Retrieving group members from Azure Active Directory

Question

Hello:

I have a NET Core 3.0 application that log users against Azure AD. I want to know how I can retrieve all members from a group, because I need to send an email to all members of that group. My understanding is that this can be done using Microsoft Graph, but I don't know how to do it and if I need to configurate permissions on Azure inside my enterprise applications.

Could you provide me with help about this? Any code example?

Thanks

Using Azure.Identity and Microsoft.Graph nuget packages. Ensure required permissions are set and requested to the application.

   var tokenProvider = new DefaultAzureCredential(true);  
     
   var client = new GraphServiceClient(  
   new DelegateAuthenticationProvider(async context = >{  
   var token = (await tokenProvider.GetTokenAsync(new TokenRequestContext(new[] {  
   "https://graph.microsoft.com/.default"  
   }))).Token;  
   context.Headers.Authorization = new AuthenticationHeaderValue("Bearer", token);  
   }));  
     
   var groups = await client.Groups.Request().Top(5).Expand("members").GetAsync();  
     
   foreach(var item in groups) {  
   Console.WriteLine($ "Group {item.Id} member count: {item.Members.Count}");  
   }
