FaultException attributeName LINQ Where ID clause

FaultException attributeName LINQ Where ID clause

Hello and thanks for your time. I'm receiving a FaultException
AtribbuteName exception when I execute:
from primary in PrimarySet
join secondary in SecondarySet
on primary.RegisterId equals secondary.Register.Id
where secondary.Id == new Guid("0EEB1E6E-C608-E311-8AEE-984BE17C6693")
// <-- problematic where clause
select primary.BooleanField
The StackTrace I receive is:

I've seen similar questions here (probl is reffered to Id fields), but I
