You can specify the directory where classes are scaffolded using -OutputDir, and -ContextDir can be used to scaffold the DbContext class into a separate directory from the entity type classes: Scaffold-DbContext. namespace Your.Namespace -context-namespace You can also override the namespace for just the DbContext class using -context-namespace: dotnet ef dbcontext scaffold. However, from EFCore 5.0 onwards, you can override the namespace for all output classes by using -namespace.

context-dir Data -output-dir Modelsīy default, the namespace will be the root namespace plus the names of any subdirectories under the project's root directory. You can specify the directory where classes are scaffolded using -output-dir, and -context-dir can be used to scaffold the DbContext class into a separate directory from the entity type classes: dotnet ef dbcontext scaffold. The entity classes and a DbContext class are scaffolded into the project's root directory and use the project's default namespace. To specify a different one, use -Context in PMC and -context in the. The scaffolded DbContext class name will be the name of the database suffixed with Context by default. While using Data Annotations will scaffold this: Specify -DataAnnotations (PMC) or -data-annotations (.NET Core CLI) to instead use data annotations when possible.įor example, using the Fluent API will scaffold this: entity.Property(e => e.Title) Fluent API or Data AnnotationsĮntity types are configured using the Fluent API by default. NET identifiers will still be fixed and synthesized names like navigation properties will still conform to. NET Core CLI will disable this behavior preserving the original database names as much as possible. Specifying the -UseDatabaseNames switch in PMC or the -use-database-names option in the. NET naming conventions for types and properties by default. Table and column names are fixed up to better match the. To include multiple tables, use an array: Scaffold-DbContext. The -Schemas option can be used to include every table within a schema, while -Tables can be used to include specific tables. To include multiple tables, specify the option multiple times: dotnet ef dbcontext scaffold. The -schema option can be used to include every table within a schema, while -table can be used to include specific tables.

You can limit which tables are reverse engineered by specifying schemas and tables. Specifying tablesĪll tables in the database schema are reverse engineered into entity types by default. The provider name is typically the same as the provider's NuGet package name. The second argument is the provider name. dotnet user-secrets initĭotnet user-secrets set ConnectionStrings:Chinook "Data Source=(localdb)\MSSQLLocalDB Initial Catalog=Chinook"ĭotnet ef dbcontext scaffold Name=ConnectionStrings:Chinook

This works well with the Secret Manager tool to keep your database password separate from your codebase. NET application that uses the hosting model and configuration system, such as an ASP.NET Core project, then you can use the Name= syntax to read the connection string from configuration. Scaffold-DbContext 'Data Source=(localdb)\MSSQLLocalDB Initial Catalog=Chinook' For example, PowerShell requires you to escape the $ character, but not \.ĭotnet ef dbcontext scaffold "Data Source=(localdb)\MSSQLLocalDB Initial Catalog=Chinook" Refer to your shell's documentation for specifics. How you quote and escape the connection string depends on which shell you are using to execute the command. The tools will use this connection string to read the database schema. The first argument to the command is a connection string to the database.

You'll also need to install an appropriate database provider for the database schema you want to reverse engineer.

Install the NuGet package for in the project you are scaffolding to.

Before reverse engineering, you'll need to install either the PMC tools (Visual Studio only) or the CLI tools.

It can be performed using the Scaffold-DbContext command of the EF Core Package Manager Console (PMC) tools or the dotnet ef dbcontext scaffold command of the. Reverse engineering is the process of scaffolding entity type classes and a DbContext class based on a database schema.
