Try installing the EF Core tool by executing the following command: dotnet tool install -global dotnet-ef * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH. NET Core program, but dotnet-ef does not exist. * You misspelled a built-in dotnet command. This should result in the initial help for the EF tools being displayed:Ĭould not execute because the specified command or file was not found. Test to see if ef commands are available to you: dotnet ef -h Both of these packages are required for any Entity Framework Core application that targets SQL Server. The second package contains the Entity Framework Core commands. The first package is the EF Core provider for SQL Server. Then create a new project: > dotnet new consoleĪdd the Entity Framework Core and Tools packages to the project: > dotnet add package Then navigate to it: > cd EFCoreScaffoldExample The following example illustrates how to use code first to generate a model from a SQL Server database in a new console application using the CLI tools.įirst, create a folder for the project: > mkdir EFCoreScaffoldexample This approach is known as Code First to an existing database. Tooling support for the EDMX file was dropped in Entity Framework Core in favor of using commands to reverse-engineer class files for the model from an existing database schema. In this approach, you reverse-engineer a model from an existing database, resulting in the generation of an EDMX file that contains the model definition and mapping information. Previous versions of Entity Framework support a Database-First approach to development.
