Switch to EF Core SQLite Provider
This document explains how to switch to the SQLite database provider for the application startup template which comes with SQL Server provider pre-configured.
Replace the Volo.Abp.EntityFrameworkCore.SqlServer Package
.EntityFrameworkCore
project in the solution depends on the Volo.Abp.EntityFrameworkCore.SqlServer NuGet package. Remove this package and add the same version of the Volo.Abp.EntityFrameworkCore.Sqlite package.
Replace the Module Dependency
Find YourProjectNameEntityFrameworkCoreModule class inside the .EntityFrameworkCore
project, remove typeof(AbpEntityFrameworkCoreSqlServerModule)
from the DependsOn
attribute, add typeof(AbpEntityFrameworkCoreSqliteModule)
(also replace using Volo.Abp.EntityFrameworkCore.SqlServer;
with using Volo.Abp.EntityFrameworkCore.Sqlite;
).
UseSqlite()
Find UseSqlServer()
calls in your solution, replace with UseSqlite()
. Check the following files:
- YourProjectNameEntityFrameworkCoreModule.cs inside the
.EntityFrameworkCore
project. - YourProjectNameMigrationsDbContextFactory.cs inside the
.EntityFrameworkCore.DbMigrations
project.
Depending on your solution structure, you may find more code files need to be changed.
Change the Connection Strings
SQLite 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 SQLite connection string options.
You typically will change the appsettings.json
inside the .DbMigrator
and .Web
projects, but it depends on your solution structure.
Re-Generate the Migrations
The startup template uses Entity Framework Core's Code First Migrations. EF Core Migrations depend on the selected DBMS provider. So, changing the DBMS provider will cause the migration fails.
- 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.
