I tried below github sample for Azure AD Authentication and successfully getting access token with proper call back URL.

https://github.com/Microsoft/BotBuilder-Samples/tree/master/samples/csharp_dotnetcore/18.bot-authentication

Modified and Configured Web.config Keys as per my application created in https://apps.dev.microsoft.com

  <add key="ActiveDirectory.Mode" value="v1" />
<add key="ActiveDirectory.ResourceId" value="https://graph.microsoft.com" />
<add key="ActiveDirectory.EndpointUrl" value="https://login.microsoftonline.com" />
<add key="ActiveDirectory.Tenant" value="xyz-xyz" />
<add key="ActiveDirectory.ClientId" value="xyz-xyz" />
<add key="ActiveDirectory.ClientSecret" value="xyz-xyz" />
 <add key="ActiveDirectory.RedirectUrl" value="http://localhost:3979/api/Callback" />
<add key="ActiveDirectory.Scopes" value="Calendars.Read,Calendars.ReadWrite,Contacts.Read,Contacts.ReadWrite,Mail.Read,Mail.ReadWrite,User.Read" />

I had crossed checked access token that i received jwt.ms. It is a valid token with scopes defined exactly as i defined in web.config.

I am able to get User Profile data from API by passing token but while trying to call "Contacts" of user, I am getting below error.

{
"error": {
    "code": "ResourceNotFound",
    "message": "Resource could not be discovered.",
    "innerError": {
        "request-id": "6f0f3ec9-76c9-4662-ac25-0bc73f887268",
        "date": "2019-03-02T17:23:35"
    }
}

}

Code calling Contact API call.

   //Get Logged in user contacts
    public async Task<IUserContactsCollectionPage> GetMyContactsAsync()
    {
        var graphClient = GetAuthenticatedClient();
        IUserContactsCollectionPage contacts = await graphClient.Me.Contacts.Request().GetAsync();
        return contacts;
    }

FYI: Displayed Sign In card in emulator Authorize sample URL is like below 

https://login.microsoftonline.com/a76b43b0-3088-4c56-ba0d-01f317b1f18c/oauth2/authorize?resource=https:%2F%2Fgraph.microsoft.com&client_id=XYZ&response_type=code&haschrome=1&redirect_uri=http:%2F%2Flocalhost:3979%2Fapi%2FCallback&x-client-SKU=PCL.Desktop&x-client-Ver=3.13.9.1126&x-client-CPU=x64&x-client-OS=Microsoft+Windows+NT+10.0.16299.0&state=<stateID>

Do you get a response if you reduce your code to await graphClient.Me.Request().GetAsync(); – Kalyan Krishna
The request you mentioned is to read use profile , I am successfully able to get response for same. I tried in postman also for "me/contacts" request with a valid token, yet same error am getting – PavanKumar GVVS
Thanks , please try to use Fiddler to capture the actual call to the graph (graph.microsoft.com). Log into Graph Explorer using the same user account that you are using into your app and try that call that very URl, does that give you a response? – Kalyan Krishna
Yes, Its giving response.Not only for Contact but also for Photo. – PavanKumar GVVS
@PavanKumarGVVS is there anything else that I can help you on this? – Md Farid Uddin Kiron

It might happens for many reason one of the very common issue is to required grant permission to your registered app. Make sure you have done following steps accordingly.

Step 1:

Login in to your portal and select your application under app registrations. Then click on settings see the screen shot below:

Once you clicked Settings new window will come up right side, click on Required Permission menu: see the screen shot below:

Step 3:

Select Required Permission Menu and assign your permission by clicking on Add button see the snap below:

Step 4:

Click on Select an API option see below:

Final Step:

Select your desired API and checked it which you are like to access for. Once finished the permission click on Done. After this step you can access your required resource / Scope from your application. Hope it will be helpful for you.Thank You. see the screen shot below:
