In this recipe, we will cover how to implement a soft delete solution with the Entity Framework, leveraging an open source library of interceptors.
We will be using the NuGet
Package Manager to install the Entity Framework 4.2 assemblies, and the Entity Framework Interceptors assemblies.
The package installer can be found at http://nuget.codeplex.com/.
We will also be using a database for connecting to the data and updating it.
We then the following command:
Install-Package Isg.EntityFramework.Interceptors.SoftDelete
Open the Improving Soft Delete solution in the included source code examples.
We start by writing out a test that will allow us to define the scope of our problem. In this case, we want to deal with soft deletable objects in the same way as we deal with other objects in our context. We define it with the following code:
using System; using System.Data.Entity; using System.Linq; using BusinessLogic; using DataAccess; using Isg.EntityFramework...
