The entity or complex type 'DomainClass' cannot be constructed in a LINQ to Entities query.

I write a linq query. It is showing error, i did not understand why this is error.
please see the query as below :

var timestamp = DateTime.Now.AddDays(-10);
var list = (from a in db.AppInfos 
                join b in db.Infos on a.App.AppId equals b.AppId
                where a.Timestamp > timestamp
                select new Info
                {
                    Id = int.MaxValue,
                    AppId=b.AppId,
                    Address = a.Address,
                    Timestamp = a.Timestamp,
                }).ToList();

It is throwing the error:
The entity or complex type 'DomainClass' cannot be constructed in a LINQ to Entities query.
I want to know why it is throwing error and what is the solution to rectify this error
