In this article, we are going to have look at dotnet CLI tool and common commands to generate and apply migrations. NET Framework like experience or for working from Visual Studio Package Manager) Using NuGet package manager console (for EF6 –.Using dotnet CLI tools (the recommended approach for.There are two ways to generate migrations This file has C# code to apply schema changes. It’s name has date and timestamp signifying when this file was generated. Physically, when you generate migration script, a new C# file is generated. A migration can be used to incrementally apply schema changes to database so as to keep database compatible with EF Core model. A migration is basically a script that is generated to keep the database in sync with the DbContext code. Then Entity Framework Core tool can be used to generate migrations. These set of classes is commonly referred to as EF Core Model. This POCO class can specify public properties and these properties would be columns of the SQL table. DbSet is a generic type, it accepts a POCO class as type parameter. Entity Framework core eliminates the need of SQL script for these tasks.įor defining a database, we can create a custom DbContext implementation, which will specify list of DbSets (a DbSet basically maps to table from relational database). Traditionally, database creation, tables creation, seed data population is done using SQL scripts. Entity Framework Core MigrationsĮntity Framework Core provides a way to interact with data stores using C# objects. Application connects to data store using connection string. Check documentation – Database Providers – for more details. Some examples can be flat file (technically possible), Mongo DB, CosmosDB, a Sqllite database, MySQL database, SQL Server database, etc.ĮF Core supports many database engines/data stores.
