Download Starter Template

Download a starter template with ASP.NET Core and Entity Framework Core to integrate SQLite. Multi-page template with ASP.NET Core 2.x + .NET Core Framework + Authentication will be explained in this document.

Install

Install the Microsoft.EntityFrameworkCore.Sqlite NuGet package to the *.EntityFrameworkCore project.

Configuration

Some configuration and workarounds are needed to use SQLite with ASP.NET Core and Entity Framework Core.

Configure DbContext

Since SQLite doesn't support multithreading, transactions should be disabled in the SQLiteDemoEntityFrameworkModule.PreInitialize() method.

NOTE:Check here for more info and workarounds.

[DependsOn(
    typeof(SQLiteDemoCoreModule), 
    typeof(AbpZeroCoreEntityFrameworkCoreModule))]
public class SQLiteDemoEntityFrameworkModule : AbpModule
{
    public override void PreInitialize()
    {
        ...
        // add this line to disable transactions
        Configuration.UnitOfWork.IsTransactional = false;
        ...
    }
}

Replace YourProjectNameDbContextConfigurer.cs with the following lines

public static class SqliteDemoDbContextConfigurer
{
    public static void Configure(DbContextOptionsBuilder<SqliteDemoDbContext> builder, string connectionString)
    {
        builder.UseSqlite(connectionString);
    }

    public static void Configure(DbContextOptionsBuilder<SqliteDemoDbContext> builder, DbConnection connection)
    {
        builder.UseSqlite(connection);
    }
 }

Configure connection string

Change the connection string to your SQLite connection in *.Web.Mvc/appsettings.json. Example:

{
  "ConnectionStrings": {
    "Default": "Data Source=SqliteDemoDb.db"
  },
  ...
}

Create Database

Remove all migration classes(include DbContextModelSnapshot) under *.EntityFrameworkCore/Migrations folder before creating database. Microsoft.EntityFrameworkCore.Sqlite will add some of its own configuration to work with Entity Framework Core.

Now it's ready to build the database.

  • Select *.Web.Mvc as the startup project.
  • Open Package Manager Console and select the *.EntityFrameworkCore project.
  • Run the add-migration Initial_Migration command
  • Run the update-database command

The SQLite integration is now complete. You can now run your project with SQLite.
