I'm using Devart to execute DB object and Store Procedure mapping.
Now i want to store in cache (using Enyim by MemCached) a Store Procedure object result.
When i'm trying to do that i have this kind of error (in short: type Devart.Data.Linq.a in Devart.Data.Linq is not signed as serializable)

This is Enyim log. I'm surely that MemCached is right configured 'cause i've tried to get and set object in cache by telnet and this has been done.
You linq expression has not been executed and for this reason there are no serializable objects to write to the cache.
If you do a ".ToList()" on the IEnumerable you should be fine.
