Remarks

The WopDefaultValueAttribute specifies the default value for the DTO field generated for the property this attribute is bound to.

The default value will be serialized for a presistent instance if

• the property is not included in the serialization view used
• the property has a null reference value
• the type of the property is one of the SQL type in the System.Data.SqlTypes namespace and the property has Null value.

To reduce the data transfer overhead WOP compiler will tag the generated DTO field with the proper DefaultValueAttribute attribute using the default value specified.

If the default value is not specified, the default instance will be used for value-type fields (0 for int, false for bool, etc.) and a null reference for reference-type fields.

The WopDefaultValueAttribute attribute cannot be used for referential or collection properties. The default value for these properties is always a null reference.
