# Switch to EF Core SQLite Provider
|
|
|
|
This document explains how to switch to the **SQLite** database provider for **[the application startup template](Startup-Templates/Application.md)** 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](https://www.nuget.org/packages/Volo.Abp.EntityFrameworkCore.SqlServer) NuGet package. Remove this package and add the same version of the [Volo.Abp.EntityFrameworkCore.Sqlite](https://www.nuget.org/packages/Volo.Abp.EntityFrameworkCore.Sqlite) package.
|
|
|
|
## Replace the Module Dependency
|
|
|
|
Find ***YourProjectName*EntityFrameworkCoreModule** 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:
|
|
|
|
* *YourProjectName*EntityFrameworkCoreModule.cs inside the `.EntityFrameworkCore` project.
|
|
* *YourProjectName*MigrationsDbContextFactory.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]( https://www.connectionstrings.com/sqlite/ ) 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](https://docs.microsoft.com/en-us/ef/core/managing-schemas/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. |
