AddAsync(driveItem) does not return

The .AddAsync(driveItem) in the following code never returns. Could anyone shed some light on this?
IPublicClientApplication publicClientApplication = PublicClientApplicationBuilder
.Create(App.ClientId)
.Build();
DeviceCodeProvider authProvider = new DeviceCodeProvider(
publicClientApplication,
new string[] { "Files.ReadWrite.All" });
GraphServiceClient graphClient = new GraphServiceClient(authProvider);
DriveItem driveItem = new DriveItem
{
Name = "Foo",
Folder = new Folder { },
AdditionalData = new Dictionary<string, object>()
{ { "#microsoft.graph.conflictBehavior", "fail" }
}
};
await graphClient
.Me
.Drive
.Root
.Children
.Request()
.AddAsync(driveItem);
[Edit 1]
I have tried folder names other than "Foo", tried names of existing or non-existing folders to no avail.
I also tried "rename" instead of "fail" for "#microsoft.graph.conflictBehavior" to no avail.
I also tried without AdditionalData to no avail.
[Edit 2]
I decided to wait for the method to return for a while (more than 10 minutes), and it finally threw an exception:
Code: generalException Message: An error occurred sending the request.

[Edit 3]
The following code has exactly the same problem:
IDriveItemChildrenCollectionPage children = await graphClient.Me.Drive.Root.Children
.Request()
.GetAsync();
This looks like a general problem for the Graph SDK.
[Edit 4]
I played the app registration of Azure Active Directory, and got the following most inner exception:
AADSTS70000: The provided value for the input parameter 'device_code' is not valid.

Again, I have to wait for more than 10 minutes for the exception to be thrown.
[Edit 5]
Not sure why exactly the same calls using Microsoft.Toolkit.Graph.Controls work perfectly.
await provider.Graph.Me.Drive.Root.Children
.Request()
.AddAsync(driveItem);

I'm not sure why this isn't returning, but Camera Roll is one of the special folders (and therefore a reserved folder name). There are a small number of these that get automatically generated either when the Drive is provisioned or when a specific service connects for the first time (i.e. "Camera Roll" is created by the OneDrive app):
Documents
Photos
Camera Roll
App Root
Music
In order to retrieve the Camera Roll folder, you request it by it's "id":
GET /me/drive/special/cameraroll

ErrorAccessDenied in Microsoft Graph API while updating IsRead property of mail item

We are using microsoft graph api for calendar and mail item processing. we pick the items from the office 365 account,process the item then we mark it as read and after that we delete that item so that it will not be processed again.
In the mark item as read process, we have below method
MarkReadMail()
{
var response = graphClient.Me.Messages[itemID].Request().Select("IsRead").GetAsync();
var msg = response.Result;
msg.IsRead = true;
graphClient.Me.Messages[itemID].Request().Select("IsRead").UpdateAsync(msg);
}
MarkReadMail() is working fine with office 365 business essential account but on the client side they have used office 365 enterprise account, it gives the below error:
Message: Exception occured in method MarkReadMail :Code: ErrorAccessDenied
Message: Access is denied. Check credentials and try again.

Although, we have provided Mail.ReadWrite permission under delegated permissions on both the account.
Please suggest.

You cannot POST the object you received from the GET as it includes read-only properties (i.e. id). You need to POST a new object with just the properties you wish to update:
graphClient
.Me
.Messages["itemID"]
.Request()
.UpdateAsync(new Message(){ IsRead = true });

.Net Core ClientWebSocket: Unable to connect to server

I'm building a web application that connects to a Predix Timeseries instance to ingest data through a websocket. When I attempt to create the socket, I get this exception:
System.Net.WebSockets.WebSocketException: 'Unable to connect to the
remote server'
I'm using this code to create my websocket, with my error being thrown on the ConnectAsync call:
public async Task openWebSocket()
{
_socket = new ClientWebSocket();
_socket.Options.SetRequestHeader(headerName: "predix-zone-id", headerValue: PREDIX_ZONE_ID_HERE);
_socket.Options.SetRequestHeader(headerName: "authorization", headerValue: "Bearer " + AUTH_TOKEN_HERE);
_socket.Options.SetRequestHeader(headerName: "content-type", headerValue: "application/json");
CancellationToken token = new CancellationToken();
var uri = new Uri(uriString: "wss://gateway-predix-data-services.run.aws-usw02-pr.ice.predix.io/v1/stream/messages");
await _socket.ConnectAsync(uri: uri, cancellationToken: token);
}
and here is my exception's stack trace:

The inner exception stack track has little more information, but noting the ThrowOnInvalidConnectState() that might be useful:

I'm not sure what else to try - lots of other posts on SO at least have some useful information in the inner exception.
I've also attempted to use Fiddler. I can see message for other services, including my auth token retrieval from UAA, but nothing from this service.
Am I missing some configuration steps somewhere? Any help or guidance would be appreciated.

I figured out the issue. The three required headers for the Predix Timeseries are:
Predix-Zone-Id: zone_id_here
Authorization: Bearer auth_token_here
Origin: "https:// hostname_here
My problem is that I tried the Origin header, but the Predix VCAP_APPLCIATION environmental variable for the application_uris doesn't include the "https://". Once I added it manually ("https://" + uri) it worked fine.

I haven't done this in C#, but "Unable to connect" sounds like it could be a network issue. Can you open a websocket to another server? Maybe this one?
https://www.websocket.org/echo.html
Could be a proxy server issue? Can you try from a different network?

"Task was canceled" errors on Azure website

As traffic to our Azure website has increased, we've been seeing an increasing number of "A task was canceled" errors. A typical trace might look like this:
Fatal web api error: Controller: CustomerUserEventsController;
Url: http://app.payboard.com/api/organizations/9ddf55d1-e0c1-4a8f-9327-eef38682e090/addcustomeruserevent?callback=jQuery210035782216349616647_1398442710964&cookieId=05be2755-dc0d-414d-b0d2-ea1986a929c3&customerId=&customerName=&customerUserId=&customerUserFirstName=&customerUserLastName=&eventName=hr-index-GET&_=1398442710965;

We used to maybe get one a day; it's been increasing gradually, so that now we're getting a couple dozen.
You'll notice that there's only framework code in the stack trace - none of our code is in there at all. So I'm a bit at a loss for how to troubleshoot it. Any suggestions on how to approach tracking these down?

See the answer here:
ASP.NET Web API OperationCanceledException when browser cancels the request
And the WebAPI bug here:
http://aspnetwebstack.codeplex.com/workitem/1797
Basically, it's expected when an HTTP request is canceled, for instance, if the user closes the page that initiated the request. To keep it from showing up in your logs, basically, you just need to create a custom message handler that suppresses the error:
/// <summary>
/// See https://stackoverflow.com/questions/22157596/asp-net-web-api-operationcanceledexception-when-browser-cancels-the-request
/// </summary>
public class CancelledTaskBugWorkaroundMessageHandler : DelegatingHandler
{
protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
var response = await base.SendAsync(request, cancellationToken);
// Try to suppress response content when the cancellation token has fired; ASP.NET will log to the Application event log if there's content in this case.
if (cancellationToken.IsCancellationRequested)
{
return new HttpResponseMessage(HttpStatusCode.InternalServerError);
}
return response;
}
}

Had the exact same problem. In my case the solution was to change the authority (an https URL) from https://login.windows.net/... to https://login.microsoftonline.com/... as it could not be reached anymore. I am not publishing the full authority as it is a specific one for our organisation. Theoretically the first one is more direct, so I used that based on advise from a Microsoft specialist. But if it cannot be reached then there is a problem. Will need to go figure out nw why it is unreachable.
Hope this will be a lead to resolve your issues.

Coen.

(C#) Azure - Null Reference Exception during Live Authentication

I followed the Live Authentication tutorial on the Azure Mobile Services page (http://www.windowsazure.com/en-us/develop/mobile/tutorials/single-sign-on-windows-8-dotnet/)
and when I run this line of code
LiveLoginResult result = await liveIDClient.LoginAsync(new[] { "wl.basic" });
I get a "NullReferenceException" no matter what I do. I tried changing "wl.basic" to "wl.signin" and that didn't work either.
I am signed into my Microsoft Account, I get the pop-up to allow it to login, the app is associated to my dev account, and I have added the client key and secret to my azure account.
Thanks a ton for the help everyone! It's driving me crazy. Here's the full code if it helps. It doesn't get passed the line stated above and I posted on MSDN as well, just thought StackOverflow would be more helpful.
private LiveConnectSession session;
private async System.Threading.Tasks.Task Authenticate()
{
LiveAuthClient liveIDClient = new LiveAuthClient("https://mobileserviceexample.azure-mobile.net/");
while (session == null)
{
// TODO: Added for testing of multiple microsoft accounts. Only works on non-connected accounts
if (liveIDClient.CanLogout)
{ liveIDClient.Logout(); }
LiveLoginResult result = await liveIDClient.LoginAsync(new[] { "wl.basic" });
if (result.Status == LiveConnectSessionStatus.Connected)
{}

I had the same issue- "Object Reference not set to the instance of an object" when calling LoginAsync.
Make sure you have entered the Redirect URL in the Live Connect setup- see Step 4 of the attached link-
