Cannot convert expression type 'NHibernate.IQueryOver<T,T>' to return type 'System.Linq.IQueryable<T>'

问题

I'm sure I'm doing this wrong, but I've been picking at it for a while. I'm trying to implement an IRepository Find method, and I just can't seem to work out how. Any help would be greatly appreciated!

The following code gives me the red squiggly line with the error message posted as the question.

   IQueryable<T> IRepository<T>.Find(Expression<Func<T, bool>> predicate)
    {
        return sessionManager.OpenSession().QueryOver<T>().Where(predicate);
    }

回答1:

You have to use .Query<T>() extension method instead.
