I'm attempting to create a method to call the Azure Rest API directly following this example https://github.com/pulumi/pulumi-azure-native/issues/601 by @tall-librarian-49374 it used to work fine, but now it seems that it's stopping at this line:

var token = await Pulumi.AzureNative.Authorization.GetClientToken.InvokeAsync();

I don't get any error, it just does not proceed past this line in my async method. Any ideas why, or what I can do to try and find the issue? I am calling this async method from the main Pulumi code using getawaiter, so my understanding is that it should wait.

Hmm, odd. We have this call in our test suite and it works fine https://github.com/pulumi/pulumi-azure-native/blob/3e3cf5fefca7a4580aef0fc313635ff76c6d0428/examples/cs-simple/MyStack.cs#L75

This is the method:

static async Task<string> SetIpGroupIp(string ipGroupId, string ip)
        {
          
                var ipGroupResourceGroup = ipGroupId.Split("/")[4];
                var ipGroupName = ipGroupId.Split("/")[8];
                var token = await Pulumi.AzureNative.Authorization.GetClientToken.InvokeAsync();
                var networkClient =
                    new NetworkManagementClient(new TokenCredentials(new StringTokenProvider(token.Token, "Bearer")))
                    {
                        SubscriptionId = ipGroupId.Split("/")[2]
                    };
                var ipGroup = (await networkClient.IpGroups.GetWithHttpMessagesAsync(ipGroupResourceGroup, ipGroupName))
                    .Body;
                Log.Warn(ipGroup.IpAddresses[0]);
                if (!ipGroup.IpAddresses.Contains(ip))
                {
                    ipGroup.IpAddresses.Add(ip);
                    await networkClient.IpGroups.CreateOrUpdateWithHttpMessagesAsync(ipGroupResourceGroup, ipGroupName,
                        ipGroup);
                }
                return ip;
        }

Yeah looks like that may have been it
