c# - Querying AzureAD Graph extension attributes with Microsoft Graph

Question

I am in the process of migrating away from Azure AD Graph API to Microsoft Graph since it is now deprecated. Previously it was possible to access extended properties against a user using Microsoft.Azure.ActiveDirectory.GraphClient .GetExtendedProperties(); call e.g:

var client = new ActiveDirectoryClient(serviceRoot, async () => await GetToken());
var user = await client.Users["user id..."].ExecuteAsync();
var properties = user.GetExtendedProperties();

I need to replicate this with equivalent calls in Microsoft Graph.

I have looked at the schemaExtensions endpoint, e.g:

GET all extensions:

/v1.0/schemaExtensions

But this doesn't appear to return the same extensions data that the AD Graph Client did.

GET user with ext:

v1.0/users/[user id]?$expand=extensions&$select=id,extension_[application id]_myExtension,onPremisesExtensionAttributes,displayName,jobTitle,identities

Where extension_[application id]_myExtension is an example extension in the format:

extension_appid_extensionname

And this doesn't return the custom extension data for the user (other properties work fine however).

How can we migrate extended properties from AD Graph Client to Microsoft Graph?

Answer 1

SchemaExtensions is different from extensionProperty. What you mentioned should be extensionProperty in Microsoft Graph.

You can use List extensionProperties to get all extensions.

Your request v1.0/users/[user id]?$expand=extensions&$select=id,extension_[application id]_myExtension,onPremisesExtensionAttributes,displayName,jobTitle,identities should be correct.

Please make sure that the application id should remove all -. The extension property format is extension_[application id without "-"]_myExtension.

For example:

GET https://graph.microsoft.com/v1.0/me?$select=id,extension_6d****fbf1fe4bc38a5a145520****89_policy,displayName

Response:

{
    "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users(id,extension_6d****fbf1fe4bc38a5a145520****89_policy,displayName)/$entity",
    "id": "98****c9-f062-48e2-8ced-22cb68****ce",
    "displayName": "Allen Wu",
    "extension_6d****fbf1fe4bc38a5a145520****89_policy": "readwrite"
}

The C# code sample:

var user = await graphClient.Users["98****c9-f062-48e2-8ced-22cb6****ce"]
    .Request()
    .Select("id,extension_6d****fbf1fe4bc38a5a145520****89_policy,displayName")
    .GetAsync();
