Thanks, Arthur Reply Brian Watt says: July 5, 2013 at 11:17 am Thanks for the article it got me sorted out with some confusion about the metadata portion of the connection string. I used this so I could have a centralized database to provide configuration setting for different environments (DEV, QA, UAT, PROD) for all of our applications
Granted, you have to do a bit of digging to find the right documentation (and StackOverflow is your friend here), but if you do, it really helps to enrich your domain model. what about comparing the two with detached context and updating a parent lots of children and a deep object graph?I believe NH.Merge command takes the cake whereas EF forces you to write your own code
http://erikej.blogspot.com/2013/02/fixing-entity-framework-designer.htmlAybe: You need to fix the generated script by hand before running it in the Toolbox, as I state in this post: GO is used after each statement, except FOREIGN KEY constraint creation statements. So in the meantime, I have updated the template to fix this, you can start using it today as replacement for the current one as follows: 1: Download my updated T4 file from here
Entity Framework, LINQ and Model-First for the Oracle Database
In this portion of the lab, you will execute a LINQ query with a lambda expression against the EMPLOYEE entity, then map a stored procedure to execute an update against all rows selected. In this tutorial, you will learn how to use Oracle Database and these three technologies with Microsoft Visual Studio and Oracle Data Provider for .NET (ODP.NET)
The data assembly can have its own connection string, if you like (this is convenient, as it will be used by the Entity Framework designer), but it will not be used by the web application at runtime. Connection strings are loaded from the configuration file for the executing assembly, which may not be the assembly which contains your Entity Framework model
Let's see each one by one.Constructor : It is an empty constructor that doesn't have any parameters, in other words it is the default constructor but it inherits the base class single string parameterized constructor. The default implementation of this method does nothing, but it can be overridden in a derived class such that the model can be further configured before it is locked down
I will show later how you can call Store Procedures in the CF approach in the next article.The CodeSo, we will create our Model class first and will then create the table in the database. When one of the CRUD operations is invoked, the Entity Framework will generate the necessary SQL to do the operation.What is CF?Whether you have your relational database is in place or not, you can always define your own model classes and their properties
As someone who's day job is all about data-access code and ado.net providers, I really don't want to go back to those days and can't think of a single reason why one would want to go back to that system. Our plans around the provider model actually open up some interesting possibilities here for plugging in various format options for defining a custom script
Simple Code First with Entity Framework 4 - Magic Unicorn Feature CTP 4 - Scott Hanselman
We'll be posting some follow-up blog posts on the ADO.NET team blog in the next week about how to customize database initialization, seed it with sample data, or do all kinds of extra goodies.2. Howver, on the tooling side, I did get a chance to talk to Damian Edwards, a developer working on some of this stuff and I put video up on Channel 9 yesterday
Code First with SQL CE - CodeProject
Model: Model - project with entity classes used for data persistence and business logic Dal: Data Access layer - project with DbContext class which is responsible for accessing database Test: A console program to test the solution Model We start building our solution with this project - because this project defines our database model. Sample Code First project with SQL CE 4.0 database Download build - 4.9 MB Download source - 54.4 KB Introduction In this article, I present a sample project using Entity Framework 6 with code first
Step4: Run and Verify data After build and run app, I use SQL Server Compact 4.0 Tooling for VS2010 to verify the database, the table and the data are added correctly. After base construction, if the inhered Fsharp class calls its constructor with property initialization, it will override the property value that base class already initialized
Understanding Database Initializers in Entity Framework Code First
The Initialize() method takes a boolean parameter that controls whether the initialization process should re-run if it has already run for the application. Using Inbuilt Database Initializers Now that you are aware of the inbuilt database initializers provided by Code First, let's see how to use them in your application
Everything SQL Server Compact: Saving images and long strings to SQL Server Compact with Entity Framework 4.1 Code First

Introduction to Entity Framework Code First
The name of the database created will be BlogDb (as specified in data context constructor) and two tables - BlogPosts and Categories - will also be created. After the fourth play was whistled dead, Harris was lying on top of Lutui and delivered a closed-fist punch through Lutui's facemask a few yards away from the Cardinals bench
Two strategies for testing Entity Framework - Effort and SQL CE - CodeProject
Use of the interface is not necessary to explain the testing methods in this article, but it's good practice for other components of the system to use interfaces as this helps with mocking when testing different components of the system. A common approach for unit testing is to abstract away Entity Framework classes (such as DbContext) and run the business logic under test against mocked objects in memory
Solmead - Wednesday, December 8, 2010 5:00:29 PM Some explicit instructions on how to convert CTP4 code to CTP5 code are needed, Fred Morrison - Wednesday, December 8, 2010 5:30:53 PM How do I update my Package Manager Console??? I sill have to use Add-Package and I am not seeing all the packages???? Paul - Wednesday, December 8, 2010 5:31:31 PM Scott I like the idea of data annotations on class properties over using fluent configuration. For join tables, you are correct that this cannot always be specified an dI will open an issue to track to make sure you can do this kind of ordering for the join table
In an upcoming blog post could you provide an example of EF Code-First that turns out to be a many-to-many relational scenario? You have exposed a few conventions over configurations for a one-to-many scenario; I guess that a MTM scenario must be as easy to implement as the OTM scenario as long as a few conventions are respected. Why is both RSVP.Dinner and RSVP.DinnerID needed? Is this a requirement? I much rather have just RSVP.Dinner (and the by convention this should create a DinnerId in the RSVPs table)

SQL Server Express connection string for Entity Framework Code First - Stack Overflow
You would have to verify that by attaching the MDF to a full-fledged SQL Server instance and see what the database stored inside the MDF is really called. Also - the file extension for SQL Server Express database files is .mdf (not .sdf - that's SQL Server Compact Edition) - you need to take that into account, too! (was a typo, according to comment by OP)
