- If you must use serialization, use the <xref:System.Runtime.Serialization.Formatters.Binary.BinaryFormatter> class instead of the <xref:System.Xml.Serialization.XmlSerializer> class. The <xref:System.Runtime.Serialization.Formatters.Binary.BinaryFormatter> class is implemented in the Base Class Library (BCL) in the mscorlib.dll assembly. The <xref:System.Xml.Serialization.XmlSerializer> is implemented in the System.Xml.dll assembly, which might be an additional DLL to load.
