How to add extensions using Microsoft Graph Client?

Question

I want to add extensions to a User using GraphClient. I couldn't find the proper C# code anywhere. Can anyone help?

Dictionary<string, object> addData = new Dictionary<string, object> {
    {
    "HoloFlag",
    currentUser.UserPrincipalName
    }
};

var extPatchObject = new OpenTypeExtension();

extPatchObject.ExtensionName = "com.holobeam3.extension";
extPatchObject.AdditionalData = addData;

try {
    var extension = await _graphClient
        .Me
        .Extensions
        .Request()
        .AddAsync(extPatchObject);
    Debug.Log(extension);
} catch (Exception ex) {
    Debug.Log(ex.Message);
}

This is what I tried so far. This returns an "access denied" exception but there is no issue in accessing existing extensions or other Me endpoints of the User.

hi Akhil can you include What you have tried so far in your question? — ArunPratap, Oct 08 '18 at 07:23
@ArunPratap Sorry for the late response. I have added my code in the question. — Akhil K J, Oct 08 '18 at 08:58
What scopes have your requested? You need to have `User.ReadWrite` in order to make changes to the current User. — Marc LaFleur, Oct 08 '18 at 13:29
@MarcLaFleur Yes. I tried using User.ReadWrite and User.ReadWrite.All. But no luck. What I actually need is the correct syntax of adding an open extension to the graph. I couldn't find that anywhere. — Akhil K J, Oct 09 '18 at 07:45
If you're getting an access denied, it is unlikely a syntax issue. It means you don't have permission to execute the action. — Marc LaFleur, Oct 09 '18 at 21:11

In order to add a new extension follow this code:

 _graphClient = new GraphServiceClient(new DelegateAuthenticationProvider(async requestMessage =>
            {
                requestMessage.Headers.Authorization = new AuthenticationHeaderValue("Bearer", AccessToken);
            }));
Dictionary<string, object> addData = new Dictionary<string, object>
                {
                    {"Key","Value" }
                };
                var extObject = new OpenTypeExtension();
                extObject.ExtensionName = "TestExtension";
                extObject.AdditionalData = addData;
                try
                {
                    await _graphClient.Users["usernamegoeshere"].Extensions.Request().AddAsync(extObject);
                }

In order to fetch an extension follow this code:

var userExtensions = await _graphClient.Me.Extensions["nameofExtension"].Request().GetAsync();

GraphServiceClient client = AuthHelper.GetAuthClient();

var currentUser = await client.Me.Request().GetAsync();
string id = currentUser.Id;

var test = await client.Me.Extensions.Request().GetAsync();

Console.WriteLine(currentUser.DisplayName);
Console.WriteLine("Click to update extension");
Console.ReadLine();

Dictionary<string, object> addData = new Dictionary<string, object>()
{
    {"Key", "Value"}
};

var extObject = new OpenTypeExtension()
{
    ExtensionName = "testExtension",
    AdditionalData = addData
};

try
{
    await client.Me.Extensions.Request().AddAsync(extObject);
}
catch (Exception ex)
{
    //
}
