The row also contains a\n type or mimetype. Type corresponds to a .NET class that support\n text/value conversion through the TypeConverter architecture.\n Classes that don't support this are serialized and stored with the\n mimetype set.\n\n The mimetype is used for serialized objects, and tells the\n ResXResourceReader how to depersist the object. This is currently not\n extensible. For a given mimetype the value must be set accordingly:\n\n Note - application/x-microsoft.net.object.binary.base64 is the format\n that the ResXResourceWriter will generate, however the reader can\n read any of the formats listed below.\n\n mimetype: application/x-microsoft.net.object.binary.base64\n value : The object must be serialized with\n : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter\n : and then encoded with base64 encoding.\n\n mimetype: application/x-microsoft.net.object.soap.base64\n value : The object must be serialized with\n : System.Runtime.Serialization.Formatters.Soap.SoapFormatter\n : and then encoded with base64 encoding.\n\n mimetype: application/x-microsoft.net.object.bytearray.base64\n value : The object must be serialized into a byte array\n : using a System.ComponentModel.TypeConverter\n : and then encoded with base64 encoding.\n -->");
