Switch to EF Core PostgreSQL Provider

    project in the solution depends on the Volo.Abp.EntityFrameworkCore.SqlServer NuGet package. Remove this package and add the same version of the package.

    Replace the Module Dependency

    Find YourProjectNameEntityFrameworkCoreModule class inside the .EntityFrameworkCore project, remove typeof(AbpEntityFrameworkCoreSqlServerModule) from the DependsOn attribute, add typeof(AbpEntityFrameworkCorePostgreSqlModule) (also replace using Volo.Abp.EntityFrameworkCore.SqlServer; with using Volo.Abp.EntityFrameworkCore.PostgreSql;).

    Find UseSqlServer() call in YourProjectNameEntityFrameworkCoreModule.cs inside the project and replace with UseNpgsql().

    Change the Connection Strings

    PostgreSql connection strings are different than SQL Server connection strings. So, check all appsettings.json files in your solution and replace the connection strings inside them. See the connectionstrings.com for details of PostgreSql connection string options.

    You typically will change the appsettings.json inside the and .Web projects, but it depends on your solution structure.

    • Delete the Migrations folder under the .EntityFrameworkCore.DbMigrations project and re-build the solution.
    • Run Add-Migration "Initial" on the Package Manager Console (select the .DbMigrator (or .Web) project as the startup project in the Solution Explorer and select the .EntityFrameworkCore.DbMigrations project as the default project in the Package Manager Console).

    This will create a database migration with all database objects (tables) configured.

    Run the .DbMigrator project to create the database and seed the initial data.

    Run the Application

    It is ready. Just run the application and enjoy coding.
