I'm writing a Xamarin app, and I'd like to give my users the ability to sign in with Azure AD from any tenant. In the world of web apps, you can do that using the common tenant; however, for some reason it seems like that's a problem for mobile apps.
Based on https://azure.microsoft.com/en-gb/documentation/articles/app-service-mobile-dotnet-how-to-use-client-library/#adal, my client code looks like this:
private async Task AadAuthenticateAsync()
{
const string authority = "https://login.microsoftonline.com/common";
const string resourceId = "<My Resource ID>";
const string clientId = "<My Client ID>";
string redirectUri = $"{AppSettings.ServerUri}/.auth/login/done";
try
{
var authContext = new AuthenticationContext(authority);
var authResult = await authContext.AcquireTokenAsync(resourceId, clientId, new Uri(redirectUri), new PlatformParameters(this));
var payload = new JObject { ["access_token"] = authResult.AccessToken };
_user = await _client.LoginAsync(MobileServiceAuthenticationProvider.WindowsAzureActiveDirectory, payload);
}
catch (Exception ex)
{
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.SetMessage(ex.Message);
builder.SetTitle("You must log in. Login Required");
builder.Create().Show();
}
}
However, when I sign in using this flow, the _client.LoginAsync step throws an exception, saying "You do not have permission to view this directory or page".
My web app is already configured to be multi-tenant, so I would have expected this flow to work as expected. Am I missing something, or is there another way to do this, given that it should be a fairly common use case?
UPDATE
When I first set this system up, I used a tenant without any users as my realm. All other tenants, including the tenant containing my own users, will be signing in using the common tenant. Following Saca's suggestion, I set up a user in mytenant.onmicrosoft.com, and signing in as that user works without a hitch: both for the authority login.microsoftonline.com/mytenant.onmicrosoft.com and login.microsoftonline.com/common. However, any user from any other tenant blows up with the same exception. In other words, although I've set the web app up as a multi-tenant app, mobile authentication seems not to accept the multi-tenant use case.
The request URL that gets invoked by _client.LoginAsync() is /.auth/login/aad.
UPDATE 2 At Saca's request, here is the stack trace:

I am sending a large video file (average file size of 50mb) to my server using HttpClient and PostAsync. I am getting an exception (see below for full exception details). I found a article that the maximimum file size that can be handled is 1mb or less is this true? If so, how can I increase the maximum file size?

If your are saving the uploaded video in server using api, May be your max request length smaller than your uploded video size. If you want to upload high size video, Then increase the max request length in your webconfig file. Here is the sample code for increasing max request lenght in web api project.
<httpRuntime targetFramework="4.5.2" maxRequestLength="15200" />
Using ExecuteAsync works for create, insert, etc., but not for select.
This are the two queries that works: CREATE TABLE t(x INTEGER PRIMARY KEY ASC, y, z) and insert into t(y, z) values(2, 2)
But select doesn't. This is my code:
SQLiteAsyncConnection conn = new SQLiteAsyncConnection(App.Databaselocation);
var result = await conn.ExecuteAsync("select y from t");
And throws this SQLiteException:

You need to use a Query/QueryAsync in order to return a result set from a sql select:
var result = await conn.QueryAsync<t>("select y from t");
I'm trying to follow the example for signing up a user in Cognito using C# from here. I had to add some stuff because AmazonCognitoIdentityProviderClient doesn't have an empty constructor. My app happens to be a Xamarin Forms app, but that shouldn't matter. I tried doing it in a .NETStandard project but kept getting an error saying that the method doesn't exist. So I switched to a PCL and now I'm getting System.IO.InvalidDataException: Cannot determine protocol. I get this error on both Android and iOS.
Here is my code:
public async Task SignupUser(string username, string password, string email)
{
const string UserPoolId = "us-east-1_XXXXXXXXX";
const string ClientId = "6xxxxxxxxxxxxxxxxxxxxxxxxx";
const string ClientSecret = "my-client-secret";
const string CognitoIdentityPoolId = "us-east-1:identity-pool-id-here";
try
{
AmazonCognitoIdentityProviderConfig providerConfig = new AmazonCognitoIdentityProviderConfig()
{
RegionEndpoint = RegionEndpoint.USEast1
};
CognitoAWSCredentials cogCreds = new CognitoAWSCredentials(CognitoIdentityPoolId, RegionEndpoint.USEast1);
IdentityProvider = new AmazonCognitoIdentityProviderClient(cogCreds, RegionEndpoint.USEast1);
SignUpRequest signUpRequest = new SignUpRequest()
{
ClientId = ClientId,
Password = password,
Username = username
};
AttributeType emailAttribute = new AttributeType()
{
Name = "email",
Value = email
};
signUpRequest.UserAttributes.Add(emailAttribute);
var signUpResult = await IdentityProvider.SignUpAsync(signUpRequest);
}
catch (Exception ex)
{
Debug.WriteLine(ex);
}
}
Here is the exception:

I solved the same issue sending "null" as credentials in AmazonCognitoIdentityProviderClient constructor:
IdentityProvider = new AmazonCognitoIdentityProviderClient(null, RegionEndpoint.USEast1);
I don't know why but it works perfectly after that, no documentation found.
var region = RegionEndpoint.GetBySystemName("us-west-2"); // use the region that you need
IdentityProvider = new AmazonCognitoIdentityProviderClient(null, region);
I have built a Xamarin forms app with PCL.
The application crashes sometimes on await Navigation.PopAsync();
I have found this https://forums.xamarin.com/discussion/62414/app-resuming-results-in-crash-with-formsappcompatactivity, but it's doesn't help
It appears only on android 5.0 and above. I'm using Xamarin.Forms 2.3.3
Here is crash log:
Xamarin caused by: android.runtime.JavaProxyThrowable: System.AggregateException: A Task's exception(s) were not observed either by Waiting on the Task or accessing its Exception property. As a result, the unobserved exception was rethrown by the finalizer thread. ---> System.AggregateException: One or more errors occurred. ---> Java.Lang.RuntimeException: Can not perform this action after onSaveInstanceState

Because the FormsAppCompatActivity
didn't allow your code to manipulate the page diplaying...
That's all. I've searched a lot, and no choice for this moment. Maybe it's a bug, anyway we had right of Push, so would that. But it wouldn't.
Solution I choosed was:
find out the target page from the history
remove it from the NavigationStack, in order to push it back to the top of the NavigationStack
then I could cut off the wanted pages of the NavigationStack
The first row is saying your task crashed so your app crashed. Adding this class
public static class LogException
{
public static void LogExceptions(this Task task)
{
task.ContinueWith(t =>
{
var aggException = t.Exception.Flatten();
foreach (var exception in aggException.InnerExceptions)
{
System.Diagnostics.Debug.WriteLine("LOG EXCEPTION catch: " + exception);
}
},
TaskContinuationOptions.OnlyOnFaulted);
}
}
and using it like this:
Task.Factory.StartNew(() => PopYourPage()).LogExceptions();
would catch these exceptions not killing your app.
What are you popping, can you explain it better?
