Question

One Author can have many Book. Table Book have Author_Id on it.

I Want a LINQ query that returns a IQueryable<Book> (So I can navigate with Book.Author.Name and stuff), but Only 1 Book per Author.

How do I do that with a LINQ?

Answer 1

Pretty sure this is it:

var books = from a in authors
            from b in a.Books.Take(1)
            select b);

Edit: Less hacky way to do this:

var books = authors.Select(author => author.Books.First())
                   .Select(book => book);
