An attempt to call XmlSerializer.Deserialize() throws an InvalidCastException
Mostly happens when de-serializing containers of classes. As a result, a container with System.Object instances is produced. This is caused by absence of default constructor in the class that is stored in the container. Surprisingly, when developing a full .NET application, the compiler does detect this problem and issues a warning (not the case when developing .NET CF apps).
