2.Sqlite quote

System.Data.SQLite

System.Data.SQLite.Core

System.Data.SQLite.EF6

System.Data.SQLite.Linq

SQLite.CodeFirst　　使EF CodeFirst支持Sqlite

Nuget the mounting

3.WebConfig configuration, installation Nuget when some did not complete the configuration, you need to ensure that the following node contains the following configuration

The connection string used EF DbContext

</connectionStrings>

EF registered within the relevant provider Sqlite

<system.data>
<DbProviderFactories>
<remove invariant="System.Data.SQLite.EF6" />
<add name="SQLite Data Provider (Entity Framework 6)" invariant="System.Data.SQLite.EF6" description=".NET Framework Data Provider for SQLite (Entity Framework 6)" type="System.Data.SQLite.EF6.SQLiteProviderFactory, System.Data.SQLite.EF6" />
<remove invariant="System.Data.SQLite" />
<add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite"/>
</DbProviderFactories>
</system.data>

4.ApplicationDbContext Configuration

The main added OnModelCreating:

the override void OnModelCreating protected (DbModelBuilder modelBuilder)
{
// Sqlite CodeFrist If the database does not exist, create
Database.SetInitializer (new SqliteCreateDatabaseIfNotExists <ApplicationDbContext> ( modelBuilder));

// use ApplicationUser Microsoft.AspNet.Identity.EntityFramework.IdentityUser based, IdentityUserRole IdentityUserLogin with no primary key, here designated

//解决“EntityType 'IdentityUserLogin' has no key defined”及“EntityType 'IdentityUserRole' has no key defined”错误

modelBuilder.Entity<IdentityUserRole>().HasKey(r => new { r.UserId, r.RoleId });
modelBuilder.Entity<IdentityUserLogin>().HasKey(r => r.UserId);
//base.OnModelCreating(modelBuilder);
}
