Today we’re providing a third CTP of the next version of Visual Studio, to gather your early feedback. For more information on this release, see Visual Studio “14” CTPs and the Visual Studio Blog. This post covers the places that Entity Framework is included in the release and some limitations to be aware of when using it.
Entity Framework 6.x Tools
There is a bug in the version of the designer included in this CTP that will cause the following error to appear when trying to use the EF Tools.
Method not found: ‘Void Microsoft.VisualStudio.PlatformUI.DpiHelper.LogicalToDeviceUnits(System.Windows.Forms.ImageList ByRef, Microsoft.VisualStudio.PlatformUI.ImageScalingModel)’.
To resolve this issue, you will need to install an updated version of the Entity Framework 6.1.1 tools for Visual Studio “14” CTP3.
Entity Framework 6.x Runtime
The Entity Framework 6.1.1 runtime is included in a number of places in Visual Studio “14” CTP.
- The runtime will be installed if you create a new model using the Entity Framework Tools in a project that does not already have the EF runtime installed.
- The runtime is pre-installed in new ASP.NET projects, depending on the project template you select.
Entity Framework 7
We recently blogged about our plans for Entity Framework 7. Visual Studio “14” CTP 3 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.
As with previous CTPs of Visual Studio “14”, this build of EF7 implements 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.
For more information on what’s included in this build of EF7, see the release notes page on our GitHub project.
We’re making good progress on the EF7 code base, but it is still in the early stages of development. If you want to experiment with a build we would recommend visiting our GitHub wiki for information on using nightly builds.
