ENTITY FRAMEWORK CODE FIRST SQL SERVER CONNECTION STRING DRIVERS
If you are using SQL Server (2008 onwards) or SQL Server LocalDB then you do not need to download any drivers for Entity Framework. In the examples, I’ll use SQL Server Express LocalDB as that was included in my Visual Studio 2017 installation but any SQL Server version will do the same thing.

You can add test data to your database within the deployment giving you the same data each time you run or install it. Also, Code First allows reverse engineering of an existing database into appropriate Entity Framework classes although I don’t cover that here. Code First means the developer writes the classes to handle all of the data interactions and storage that is required and Code First builds those structures for you in the database.

What really got me excited was a few years back when Microsoft added the Code First approach to the Entity Framework. I’ve never tried to switch from say Oracle to SQL Server using EF myself.

The theory is that if I want to switch from one relational database provider then I do not have to rebuild my code, just a few configuration changes and I’m done. A few years later and Entity Framework (EF) was born to replace Data Objects and included lots of powerful features. Quite a lot of developers, myself included, started to build a data abstraction layer so that switching servers or making changes did not affect the code (at least existing code would still run).įrom memory, I think Microsoft created Data Objects around 2005, which was a first attempt to standardise their own database abstraction layer. If you were to switch from say Oracle to SQL Server then this data tier or even the whole product would need to have a major overhaul. Some people built separate business logic code or added other tiers to their applications so that not everything needed to be rebuilt when you had to make a structural change to say the database or switch servers. If a database object changed or you needed to switch to another database then coding changes were required quite often ending up in a rebuild. The application would either populate tables or call database server functions or procedures directly. In the past, developers coded either directly from their application to a database.
ENTITY FRAMEWORK CODE FIRST SQL SERVER CONNECTION STRING SOFTWARE
To start off it is probably worth mentioning what the Entity Framework is and why it is important in software development and also what Code First means. In this Code First exercise, I will install SQL Server LocalDB, create a Visual Studio project, install Entity Framework and then create the database objects (including some test data) through the Visual Studio project using Entity Framework Code First. Have you installed EntityFramework.SqlServerCompact NuGet package? Once it is installed .4.0 provider name is added and it should be used in the connection string.Ĭheck if SqlServerCompact provider is added to your this article, I will walk through an example in an attempt to show Entity Framework Code First. I think that you should check your providerName.

In one of my projects I used SQL Server Compact 4.0 and my connection string was simple enough:
