Code First code snippets

Visual Studio code snippets for DevForce 2010 "Code First" can speed development of your entity models, reducing tedium and errors.

Snippets

There are five code snippets:

cflistnavprop.snippet, shortcut "cfnav",  emits a "list navigation" property returning a DevForce RelatedEntityList of entities. For example, a Customer entity might have an "Orders" list navigation property returning the customer's Orders. 

cfrefnavprop.snippet, shortcut "cfref", emits a "reference navigation" property and a companion foreign key property. The navigation property returns a single entity. For example a "Customer" property that returns the parent Customer entity. A reference navigation property usually has a corresponding foreign key property; a "Customer" property of an Order probably should have a foreign key property named CustomerId.

cfentitymanager.snippet, shortcut "cfentitymanager",  emits a custom EntityManager for your model. It consists mostly of standard constructors and the prototype of a query method. It produces a lot of inescapable boiler plate code that you'll probably need only once per application model.

cfentityqueryprop.snippet, shortcut "cfeq",  emits an EntityQuery<T> property for a custom EntityManager. For example, to add a Customers query property, use this snippet to add "public EntityQuery<Customer> Customers {get; set;}" to your EntityManager.

cfdbsetproperty.snippet, shortcut "cfdbset",  emits a DbSet<T> property for a custom DbContext. For example, to expose Customer entities, use this snippet to add "public DbSet<Customer> Customers {get; set;}" to your DbContext.

Use in your code

Microsoft describes numerous ways to use a code snippet. We prefer the "short-cut" technique:

1. Put the cursor where you want to insert the code snippet.
2. Type the shortcut for the code snippet (e.g. "cfrefnavprop").
3. Press TAB, TAB to invoke the code snippet.
