Only parameterless constructors and initializers are supported in LINQ to Entities

Question

I have this error in this linq expression :

var naleznosci = (from nalTmp in db.Naleznosci
                              where nalTmp.idDziecko == idDziec
           


        

Answer 1

Just ToList() the DbSet before the Select statement.. the actual DbSet is saved as a query, it's not fulfilled yet. After calling ToList() you're playing with objects, and then you can use a non-default constructor in the query.

Not the most efficient way usage-time wise, but it's an option on small sets.
