The official source of information on Managed Providers, DataSet & Entity Framework from Microsoft
Visual Studio 14 CTP was made available today, see the announcement post on the Visual Studio blog for more details. This post covers the places that Entity Framework is included in the release and some limitations to be aware of when using it.
As with past versions of Visual Studio, the Entity Framework Tools are included in-the-box. These tools are capable of working with models created with all versions of Entity Framework up to and including EF6.x.
Visual Studio 14 CTP includes an older build of the EF6 tooling which does not include the bug fixes and improvements from the 6.1.0 and 6.1.1 releases. Future previews of Visual Studio 14 will be updated to the latest version of the tooling.
At this stage, there isn’t a version of the 6.1.0 or 6.1.1 tooling that can be installed on Visual Studio 14.
An older build of the EF6 runtime is included in a number of places in Visual Studio 14 CTP. This build does not include the bug fixes and improvements from the 6.1.0 and 6.1.1 releases.
We recommend using NuGet to update to the latest version of the runtime. At the time of writing 6.1.0 was the latest stable release and 6.1.1-beta1 was available. For detailed information on how to upgrade, see Updating a Package in the NuGet documentation.
We recently blogged about our plans for Entity Framework 7. Visual Studio 14 CTP includes an early preview of ASP.NET vNext, which in turn includes a very early build of EF7. The EF7 runtime is installed in new ASP vNext projects that are created.
This build of EF7 only implements very basic functionality and there are a number of limitations with the features that are implemented. Please bear in mind that this preview is designed to give you an idea of what the experience will be like and you will quickly hit limitations if you deviate from the code from the default project template.
The EF7 code base is still in the very early stages of development, but if you want to experiment with a build we would recommend visiting our GitHub wiki for information on using nightly builds. Just remember that there are lots of things that don’t work… seriously… we warned you :)!
