NH-3200 - Exception in linq query for use "Type" for property name

[nhibernate-bot]

I have a query by linq to nhibernate.

    var q = SessionInstance.Query<Evidence>()
           .Select(x => new Evidence(x.Id)
            {
                Type = x.Type,
                StartDate = x.StartDate,
                EndDate = x.EndDate
            })    
            .ToList();

It has a exception by this Message :

NHibernate.Exceptions.GenericADOException :
Could not execute query<SQL: SQL not available>
{"Exception has been thrown by the target of an invocation."}
{"Specified cast is not valid."}

But by rename Type property to Type1, My problem is resolved.

    q = q.Select(x => new Evidence(x.Id)
        {
            Type1 = x.Type1,
            StartDate = x.StartDate,
            EndDate = x.EndDate
        });

My Evidence class is :

    public class Evidence
    {
        public long Id;
        public EvidenceEnumType? Type;
        public DateTime? StartDate;
        public DateTime? EndDate;
    }

Why?
Is a solution exist for use Type name for a property?
