Sqlite not work with Entity Framework 6 - entity-framework

Question

I have a small project with sqlite and entity framework 6.
I install sqlite by Package Manager Console: PM>Install-Package System.Data.SQLite
In my web.config:
<connectionStrings>
<remove name="demoSQLiteonnectionString" />
<add name="demoSQLiteonnectionString" connectionString="Data Source=|App_Data|DemoData.s3db" providerName="System.Data.SQLite.EF6" />
</connectionStrings>
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
<parameters>
<parameter value="v11.0" />
</parameters>
</defaultConnectionFactory>
<providers>
<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
<provider invariantName="System.Data.SQLite.EF6" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6" />
</providers>
</entityFramework>
<system.data>
<DbProviderFactories>
<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" />
<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" />
</DbProviderFactories>
</system.data>
In my context class:
public class DataContext : DbContext
{
public DataContext()
: base("demoSQLiteonnectionString")
{
Database.SetInitializer(new CreateDatabaseIfNotExists<DataContext>());
}
public DbSet<Client> Client { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
// Chinook Database does not pluralize table names
modelBuilder.Conventions
.Remove<PluralizingTableNameConvention>();
}
}
When get instance of context: var context = new DataContext(),
it shows this error:
Additional information: No Entity Framework provider found for the ADO.NET provider with invariant name 'System.Data.SQLite'. Make sure the provider is registered in the 'entityFramework' section of the application config file. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information.
How to fix this problem?

Answer 1

You Should change the app config file to
<providers>
<provider invariantName="**System.Data.SQLite.EF6**" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6" />
</providers>
</providers>
to
<providers>
<provider invariantName="**System.Data.SQLite**" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6" />
</providers>
</providers>
and change the configuration file to :
public class DataContext : DbContext
{
public DataContext()
: base("demoSQLiteonnectionString")
{
}
public DbSet<Client> Client { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
// Chinook Database does not pluralize table names
modelBuilder.Conventions
.Remove<PluralizingTableNameConvention>();
Database.SetInitializer(new SqliteCreateDatabaseIfNotExists<DataContext>(modelBuilder));
}
}
