Hi,

C#

Expression<Func<SystemUser, object>>[] includeProperties = { x => x.Company.CompanyAddresses.Where(z=>z.AddressTypeId==5).Select(y => y.Address.Country.CountryRegions) };
                    var user = _SystemUserRepository.GetById(userID, includeProperties);

while I am executing the above query, it throws exception as "The Include path expression must refer to a navigation property defined on the type. Use dotted paths for reference navigation properties and the Select operator for collection navigation properties."

if I remove "where" clause from query, it executes fine.

could any one explain the reason?

"if I remove "where" clause from query, it executes fine."
That's probably the clue. At a guess - and without your data that's all it can be - you need to look at how many values you have in the collection which match the criteria. I'm guessing that none do, so the GetById is being passed no values.
