Entityframework Join using join method and lambdas

Question

It seems there are different ways to do joins using linq. One is more straightforward and involves just joining tables like this:

var found = from c in s.cat         


        

Answer 1

If you have configured navigation property 1-n I would recommend you to use:

var query = db.Categories                                  // source
   .SelectMany(c=>c.CategoryMaps,                          // join
      (c, cm) => new { Category = c, CategoryMaps = cm })  // project result
   .Select(x => x.Category);                               // select result

Much more clearer to me and looks better with multiple nested joins.
