The EF Core context and entity classes are in a .NET Core class library. A .NET Core console app or web app references the class library. It's also possible to put migrations code in a class library separate from the EF Core context. Other target frameworks.

I'm currently working on an inherited .NET Core project and I'm loving the experience. I'm still using the project.json project format instead of the newer *.csproj & msbuild one Hi All, I'm working on a database first approach with EF Core 3.1 and 5 pre-release using EF Power Tools to build my entities. I've hit a 'cartesian explosion' issue when I query the parent data with the .Include(x => x.ChildRecords) code and I wondered if there is a clean way to avoid this while still retaining the parent child relationships as per the generated database first code. Currently. To use .NET CLI, add <DotNetCliToolReference Include=Microsoft.EntityFrameworkCore.Tools.DotNet Version=2.0.0 /> under <ItemGroup> node by editing your .NET Core project's .csproj file.

If you are not using windows OS, then using the command line tools is the only option available to you Entity Framework Core (EF Core) is an Object-Relational Mapping (ORM). It works between the application and the database.

For the sample application I'm using Visual Studio 2017 RC with the .NET Core Tools MSBuild alpha and .NET Core 1.1. You can easily use Visual Studio 2015 Update 3 with .NET Core 1.0 as well. The features shown here are also available for Entity Framework Core 1.0. The Book type defines the model that will be used from the EF Core context Great question. What I would suggest is separation of concerns to solve this problem. Create an API for the EF6 stuff and another for the EF Core work. Then interact with them as needed. Design the ef6 based API as closely as you can to how EF Core works. Then when the DB2 support comes on board for EFCore, you can migrate the ef6 api to ef core

Commonly Used Types: Microsoft.EntityFrameworkCore.DbContext Microsoft.EntityFrameworkCore.DbSe EF Core, AspNet Core, Docker, MySql. This setup describes the ability to run AspNet Core and MySql db in docker containers during dev and still be able to use EF Core tools in order to run migrations against the MySql database running in a container Entity Framework Core can be also used with .NET Core console applications. Although ASP.NET Core provides some better mechanisms for application configuring and also dependency injection we can build simple database context factory and hide some dirty details from other parts of code in our application Entity Framework Core (EF Core) is the flavor or Entity Framework that runs on top of the .NET Core runtime.
