SQLite with EntityFramework with Code-First

c# ef-code-first entity-framework sqlite system.data.sqlite


I am trying to create an embedded SQLite database on the fly with the EF however, I can't get it to work, the database file is never getting created.

I have EF 4.2 and latest version SQLite

Here is what I have


<?xml version="1.0"?>
      <remove invariant="System.Data.SQLite"/>
      <add name="SQLite Data Provider"
           description=".Net Framework Data Provider for SQLite"
           type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite"/>
    <add name="DataContext"
         connectionString="Data Source=test.db;Version=3;New=True;"
         providerName="System.Data.SQLite" />
    <supportedRuntime version="v4.0" />

DB initializer (to put some content in)

class PageDbInitializer : DropCreateDatabaseAlways<PageDB>
    protected override void Seed(PageDB context)
        for (int i = 0; i < 10; i++)
            WebPage page = new WebPage() { Name = "Page" + (i + 1) };


class PageDB : DbContext
        public DbSet<WebPage> Pages { get; set; }

And finally in the main()

Database.SetInitializer( new PageDbInitializer() );

I believe I have some steps missing, but can't find them out.

Accepted Answer

System.Data.SQLite is in current version only EFv1 compatible provider (1, 2). It means it doesn't have EFv4 (EFv4.2 is wrapper around EFv4) features including database creation and deletion (check DbProviderServices differences for .NET 3.5 and .NET 4.0 in MSDN). Because of that you cannot use automatic database creation with code first when working with SQLite. You must create database and all tables manually.

As an alternative you can use different provider for SQLite. For example Devart's SQLite provider claims it supports EFv4 and 4.1 and thus database creation.

Check this out:


Also available as a NuGet

It adds some DB Initializers to your ptoject, such as SqliteCreateDatabaseIfNotExists

Here's the example of the web site:

public class MyDbContext : DbContext
    public MyDbContext()
        : base("ConnectionStringName") { }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
        var sqliteConnectionInitializer = new SqliteCreateDatabaseIfNotExists<MyDbContext>(
            Database.Connection.ConnectionString, modelBuilder);
