Shadow properties are fields that don’t exist in the class itself, but are treated as if they did by Entity Framework. They can participate in queries, create/update operations, and database migrations.
Entity Framework was created solely for working with relational data on the full version of .NET. In EF 7, neither of those statements is true.
Version 7 of Entity Framework represents a major redesign of the 6-year-old ORM. As such, Microsoft will not be recommending the initial release of EF 7 for existing projects. Rather, it is only meant for projects that are using ASP.NET 5 and .NET Core.
When a database administrators think of high performance data loading, they are thinking of bulk operations, a feature noticeably lacking in Entity Framework. But that doesn’t have to be the case. We recently spoke with Jonathan Magnan of ZZZ Projects about their new offerings.
Entity Framework is being rebooted with an initiative called “Entity Framework Everywhere”. The goal of this project is dramatically reduce both the complexity of Entity Framework and the resources needed to run applications that use it. This will in turn allow it to run on a wider variety of platforms including Windows Store and Windows Phone.
Microsoft recently added Entity Framework 6 support for DynamicData and EntityDataSource controls with in addition to refreshed the templates. It also has few known issues as the support is limited to C# and Web Application projects.
Entity Framework continues to have performance problems when using larger EDMX models to generate classes. “If the EDMX only has one entity type materialization takes 840 ms […] but when the EDMX contains a richer model, for example one with 67 entity types and 92 associations, the same test takes 7246 ms to complete”.

With their focus on Xamarin, the commercial version of Mono, it often seems like Mono is being is being neglected. But the nine year old platform is still seeing active development. Mono 3.0.12 brings with several new features including support for Portable Class Libraries and cookies in WCF.
As part of the beta 1 release, Entity Framework 6 has added new methods to DbSet: AddRange, RemoveRange, and FindAsync. But what will happen with IDbSet, the matching abstract interface?
In order to support the new open source model for Entity Framework, it had to cut its ties to the core distribution of the .NET Framework. Unfortunately this required a breaking change to the namespaces exposed by the ORM in version 6.
Much has been written on the topic of ORMs and its failings. Most of the objections fall into two categories: Separation of Concerns and Object Oriented Design. For the Entity Framework we have good news for one these.
