ASP.NET.MVC, EF 6 and SQLite 3 - error finding a table in a database

I'm trying to get to work ASP.NET.MVC4, EF6 and SQlite 3.

I have installed these packages:

I have created the database and all required tables. The database files is in *\bin\ folder of the project. To confirm the SQLite database and tables exist, I have run .schema command:

CREATE TABLE Wydarzenie(WydarzenieID INTEGER PRIMARY KEY AUTOINCREMENT, NazwaWydarzenia TEXT NOT NULL, Informacja TEXT);
CREATE TABLE Osoba(OsobaID INTEGER PRIMARY KEY AUTOINCREMENT, Imie TEXT NOT NULL, Nazwisko TEXT, Informacja TEXT);
CREATE TABLE GrupaWydarzenia(OsobaID INTEGER NOT NULL, WydarzenieID INTEGER NOT NULL, Przypomnienie INTEGER NOT NULL, PRIMARY KEY (OsobaID, WydarzenieID), FOREIGN KEY(OsobaID) REFERENCES Osoby(OsobaID), FOREIGN KEY(WydarzenieID) REFERENCES Wydarzenia(WydarzenieID));

I have also double checked we,config connection string and I think VS2010 finds it (it would be error such as "CreateDatabase" is not supported by this provider or something like that). The connection string:

<connectionStrings>
    <add name="WDBContext" connectionString="Data Source=|DataDirectory|wydarzenia.sqlite; Version=3" providerName="System.Data.SQLite.EF6" />
</connectionStrings>

Yet, for some reason the VS2010 says:

SQL logic error or missing database\r\nno such table: Osoba

I cannot understand why the table cannot be found! The WDBContext class is defined as

public class WDBContext : DbContext
{
    public DbSet<Wydarzenie> Wydarzenia { get; set; }
    public DbSet<Osoba> Osoby { get; set; }
    public DbSet<GrupaWydarzenia> GrupyWydarzen { get; set; }

    public WDBContext()
        : base("WDBContext")
    {
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();

        modelBuilder.Configurations.Add(new WydarzenieEntityConfiguration());
        modelBuilder.Configurations.Add(new OsobaEntityConfiguration());
        modelBuilder.Configurations.Add(new GrupaWydarzeniaEntityConfiguration());

        base.OnModelCreating(modelBuilder);
    }
}
