I use the NuGet-package WindowsAzure.Messaging.Managed 0.1.7.5.
When I try to create a subscription the subscription is created but I get a SerializationException.
Subscription sub = await Subscription.CreateAsync(topic, subscriptionName, connectionString);
An exception of type 'System.Runtime.Serialization.SerializationException' occurred in mscorlib.dll but was not handled in user code
Additional information: There was an error deserializing the object of type Microsoft.WindowsAzure.Messaging.SubscriptionDescription. The UTC representation of the date falls outside the year range 1-9999.
