In this recipe, we will be using multiple contexts to select the objects and update them, without having the knowledge of where they came from. This is a very common scenario when entities, or representations of entities, are being received by a web service or any other situation where the original context may have fallen out of scope.
We will be using the
NuGet Package Manager to install the Entity Framework 4.1 assemblies.
The package installer can be found at http://nuget.org.
We will also be using a database for connecting to the data and updating it.
Open the Improving Detached Objects with Unit Of Work solution in the included source code examples.
