In the post I’ll show how you can use the Repository Pattern. (more)

Trying to delete a record in many to many relationship can be a bit tricky. In this scenario I have a person record that can be tied to multiple address records. Here is our database setup:   When creating the data model the Entity Framework will hide all the details for us of creating and updating the intermediary "PersonAddress" table.  Here's what's generated by the designer: When generating our Ria Service, if we select the "Enable Editing" option for our "Address" table it will create all the C...

The title of this post is a tongue-in-cheek reference to SubSonic’s inline query by the same name, which in turn is a reference to the blogger Jeff Atwood’s blog who you should all know.  Rob Conery, the SubSonic project leader, named the inline query class CodingHorror after he allegedly read Jeff Atwood’s post titled Embracing Languages Inside Languages, in which he bestowed the virtues of inline SQL inside your code, instead of the standard bequeathed statement that I bet you all have heard “We do all...

Tip 47 – How fix-up can make it hard to change relationships Problem: Take this code: Category oldCategory = ctx.Categories     .Include("Products")     .First(c => c.Name == "Drink"); Category newCategory = new Category {Name = "Beverage"}; foreach(Product product in oldCategory.Products) {     newCategory.Products.Add(product); } Ignore for a second that in this example the solution is probably just to rename the oldCategory "Beverages" - Coming up with real world samples gets hard...
