c# - AppFabric cache and serializing IQueryable objects -

i experimenting appfabric caching , have run issue saving retrieved data in cache. root of problem seems appfabric caching requires data have datacontract , datamember attributes applied class being saved.

if case, how can save (simplified code):

var q = (from u in dbcontext.users                          select new                          {                              name = u.name,                              id = u.rowid                          });  cache.put(“test”, q.tolist()); 

calling put causes exception:

system.runtime.serialization.invaliddatacontractexception caught  message=type '<>f__anonymoustypec`6[system.int32,system.string,system.nullable`1[system.int32],system.boolean,system.nullable`1[system.int32],system.int32]' cannot  serialized. consider marking datacontractattribute attribute, ,  marking of members want serialized datamemberattribute  attribute.  if type collection, consider marking collectiondatacontractattribute.  see microsoft .net framework  documentation other supported types. 

how can serialize results of iqueryable appfabric can cache it?

thank you,

rick

it isn't you're trying iqueryable, it's type anonymous. try making class results , creating 1 of store.

[serializable] public class useridpair {     public string name {get;set;}     public int id {get;set;} }  var q = (from u in dbcontext.users     select new useridpair     {         name = u.name,         id = u.rowid     });  cache.put(“test”, q.tolist()); 

make sure class serializable
