【问题描述】:
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。我正在尝试实现一个非常简单的使用实体框架和 SQLite 的目标,我希望使用代码优先的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。
以下是我的应用程序代码:
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,这里我只是尝试将一个新的 ApplicationConfiguration obj 添加到 DbContext 的 AppConfig DbSet 中。
但是,在执行 Add 方法行时,应用程序会抛出以下异常:
System.IO.FileLoadException was caught

版本
1.0.66.0似乎很旧,我不确定它是否与 .Net 4.5 (See here) 兼容
