Question

我使用VS 2013和.Net 4.5框架创建了一个简单的控制台应用程序。我试图实现一个使用Entity Framework＆amp; amp;的非常简单的目标。 SQLite，我希望使用代码优先方法从我的模型中创建一个表。我已经安装了NuGet package以便能够在我的项目中使用LINQ to SQLite。

以下是我的申请代码：

 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; }
}

所以，这里我只是尝试将新的ApplicationConfiguration obj添加到DbContext的AppConfig DbSet中。

但是，在执行Add方法行时，应用程序抛出以下异常：

System.IO.FileLoadException was caught

Answer 1

我在Visual Studio 2013 Update 4上使用EF 6.1.3，SQLite 1.0.96.0和SQLite.CodeFirst 0.9.5.0而没有此类问题。尝试更新。

与EF 6一起使用时无法加载文件或程序集“System.Data.SQLite”
