Entity Framework Code Only option

.NET 4.0 and VS 2010 introduce a new feature for the Entity Framework called model first.  In addition, you will now be able to have a code only model. Written with POCOs and a simple class derived from ObjectContext and you are on the way…

Using Stored Procedures with Entity Framework

Yesterday i was attempting to use a stored procedure with the Entity Framework through the “function import” features and couldn’t get the auto-gen feature to expose the function on the Context.  The stored procedure was returning a scalar value which at this point doesn’t seem to be supported through auto-gen.  Choosing an Entity, however works fine. Further digging this morning led me to this article on the ADO.NET team blog explaining the issues with return types and stored procedures in Entity Framework.  The article also links to another great article showing how to return custom types two ways:  one way through the entity framework itself, the other through the use of extension methods.

Using T4 to Generate Stored Procs for Entity Framework

T4 code generation has been on my short list of things to look into but keeps getting put off as i navigate down some other endless path.  Meanwhile, I found a nice article on using T4 to generate stored procs for CRUD operations for the Entity Framework.

WCF and Large File Transfers

I’ve been doing a bit of WCF lately and picked up on a few things that will be helpful for me to remember.  To speed large transfers switch the messageEncoding on the binding to be MTOM, otherwise your data will get base64 encoded inside the XML.

  1. Streaming requires a MessageContract and not a DataContract
  2. Streaming doesn’t work on wsHTTPbinding.
  3. A MessageContract can only have one Member in the body (stream).

Another good piece:
