Could not load file or assembly 'System.Data.SQLite' when using with EF 6

.net-assembly c# entity-framework-6 sqlite

Question

I have created a simple console application using VS 2013 and .Net 4.5 framework. I am trying to achieve a very simple objective of using Entity Framework & SQLite, I wish to create a table from my model, using the code-first approach. I have installed the NuGet package to be able to use LINQ to SQLite in my project.

Below is the code of my application:

 static void Main(string[] args)
 {
     string _databaseFilePath = Path.Combine(Path.GetDirectoryName(Assembly.GetEntryAssembly().Location), "TestSqliteDb.sdb");

     if (!File.Exists(_databaseFilePath))
         SQLiteConnection.CreateFile(_databaseFilePath);

     using (var testDb = new TestMovieDbContext())
     {
         testDb.AppConfigTable.Add(
             new ApplicationConfiguration
             {
                 ConfigKey = "CreatedDate",
                 ConfigValue = "12-03-2015"
             });
      }

public class TestMovieDbContext : DbContext
{
    public TestMovieDbContext()
        : base("name=TestDbConStr")
    {
    }

    public DbSet<ApplicationConfiguration> AppConfigTable { get; set; }
}

public class ApplicationConfiguration
{
    [Key]
    public string ConfigKey { get; set; }
    public string ConfigValue { get; set; }
}

So, here I'm simply trying to add a new ApplicationConfiguration obj to the AppConfig DbSet of the DbContext.

However, at the time of executing the Add method line, the application throws the below exception:

System.IO.FileLoadException was caught
  HResult=-2146234304
