Pass list of custom types in Silverlight Ria services

i have to read csv file. from csv file, i have to create a List list And then return it to the calling method.

do you recommend any other alternative? also CustomClass has a property List. It's always null on the silverlight side开发者_StackOverflow社区. Can you tell me what the solution is?

The solution is to use [Include] and [Associate] attributes for properties of the class.

Also to read data, we can return an IEnumerable type e.g. list, ilist from our ria service to the silverlight application
