Fluent SDK doesn't run under ASP.NET in .Net 4.5.2

Guys, I might be doing something wrong, but I can’t get anything to work at all.

AzureCredentials azureCredentials = new AzureCredentials(servicePrincipalLoginInformation, TenantId, AzureEnvironment.AzureGlobalCloud);
            Azure azure = Azure.Authenticate(azureCredentials).WithSubscription(SubscriptionId) as Azure;

This is my auth code. Doesn’t return any error. After I am trying to provision a Resource group and its just stuck without any errors or anything. The same behavior for any api call. Any idea?

message.InnerText = "Resource Group Doesnt Exists " + DateTime.Now.ToShortDateString();

var groupName = SdkContext.RandomResourceName(dealerID + "_" +"rsGroup_", 24);
resourceGroup = azure.ResourceGroups
           .Define(groupName)
           .WithRegion(Region.AustraliaSouthEast)
           .Create();

message.InnerText = "Creating Resource Group " + DateTime.Now.ToShortDateString();

@fredcicles Sync methods should also be fixed in the next release (shipping end of August)

@abhi1509 - FYI, just verified. CheckExistence hangs while CheckExistenceAsync works fine. here is the code:

public async Task<ActionResult> Index()
{
    var credentials = SdkContext.AzureCredentialsFactory.FromFile(Environment.GetEnvironmentVariable("AZURE_AUTH_LOCATION"));

    var azure = Azure
        .Configure()
        .WithLogLevel(HttpLoggingDelegatingHandler.Level.None)
        .Authenticate(credentials)
        .WithDefaultSubscription();

	var result = await azure.ResourceGroups.CheckExistenceAsync("somerandomnamegoeshere");
    ...
}

This issue is blocking Create scenarios where we create each dependent resource in parallel.
