MVC 5 with EF 6 in Visual Basic - Async and Stored Procedures with the Entity Framework

13 June 2014 13:40

VB.Net ASP.NET MVC Entity Framework

This tutorial is the ninth in a series of 12 that teach you how to build MVC 5 applications using Entity Framework for data access and Visual Basic. In earlier tutorials you learned how to read and update data using the synchronous programming model. In this tutorial you see how to implement the asynchronous programming model. Asynchronous code can help an application perform better because it makes better use of server resources.

MVC 5 with EF 6 in Visual Basic - Updating Related Data

13 June 2014 13:39

VB.Net ASP.NET MVC Entity Framework

This tutorial is the eighth in a series of 12 that teach you how to build MVC 5 applications using Entity Framework for data access and Visual Basic. In the previous tutorial you displayed related data; in this tutorial you'll update related data. For most relationships, this can be done by updating either foreign key fields or navigation properties. For many-to-many relationships, the Entity Framework doesn't expose the join table directly, so you add and remove entities to and from the appropriate navigation properties.

MVC 5 with EF 6 in Visual Basic - Creating a More Complex Data Model

13 June 2014 13:38

VB.Net ASP.NET MVC Entity Framework

This tutorial is the sixth in a series of 12 that teach you how to build MVC 5 applications using Entity Framework for data access and Visual Basic. In the previous tutorials you worked with a simple data model that was composed of three entities. In this tutorial you'll add more entities and relationships, and you'll customize the data model by specifying formatting, validation, and database mapping rules. You'll see two ways to customize the data model:  by adding attributes to entity classes and by adding code to the database context class.

MVC 5 with EF 6 in Visual Basic - Code First Migrations and Deployment

13 June 2014 13:37

VB.Net ASP.NET MVC Entity Framework

This tutorial is the fifth in a series of 12 that teach you how to build MVC 5 applications using Entity Framework for data access and Visual Basic. This tutorial covers how to enable Code First Migrations and then deploy your database to Windows Azure. The Migrations feature enables you to change the data model and deploy your changes to production by updating the database schema without having to drop and re-create the database. The section covering deployment to Azure is optional; you can continue with the remaining tutorials without having deployed the project.

MVC 5 with EF 6 in Visual Basic - Creating an Entity Framework Data Model

13 June 2014 13:33

VB.Net ASP.NET MVC Entity Framework

This tutorial is the first in a series of a Visual Basic versions of the Getting Started with EF 6 using MVC 5 tutorials published on the www.asp.net site. The original series, produced by Tom Dykstra and Rick Anderson ( @RickAndMSFT ) was written using the C# language. My versions keep as close to the originals as possible, changing only the coding language. The narrative text is largely unchanged from the original and is used with permission from Microsoft.

Entity Framework

I managed to generate this error twice within a few days while working with the Entity Framework and SQL Server 2012. I had to resort to searching for a resolution on both occasions so I'm posting about it to sear the cause and solution into my brain.

Code First Migrations With ASP.NET Web Pages Sites

28 August 2013 20:14

Visual Studio Entity Framework ASP.NET Web Pages WebMatrix

Entity Framework Code First Migrations enable changes to your model to be propagated to your database through code. Prior to the introduction of migrations, changes to the model resulted in the database being recreated from scratch with attendant loss of data. During development, this may not cause too many problems, but once the database has been deployed into production, it's another story. Migrations solve the problem in that changes are applied to the database schema without loss of data.

LINQ ASP.NET MVC Entity Framework

As you delve more into ASP.NET MVC you start to come across a whole new way of doing things that Web Forms development didn't really expose you to. Inversion of Control (IoC) and Dependency Injection (DI) are two phrases that crop up a lot in the MVC space. So what are they all about? And should you care?
