我有一个C＃项目，我正在使用Entity Framework 6.1。我有一些迁移文件和同一文件夹中的Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
#If VBA7 Then
Declare PtrSafe Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As LongLong, ByVal dwExtraInfo As LongPtr)
#Else
Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
#End If
Private Const VK_SNAPSHOT As Byte = 44
Public Function StoreScreenShotFrom_As(URL_Dest As String, Img_Name As String, Img_Type As String)
Dim IE As Object, IECaption As String
Dim aXL As Object, aWB As Object, aSh As Object, aChO As Object, Img_Path As String
Img_Path = VBA.Environ$("temp") & "\" & Img_Name & "." & Img_Type
Set IE = CreateObject("InternetExplorer.Application")
With IE
.Visible = True
.FullScreen = True
.Navigate URL_Dest

文件。 Configuration.cs包含以下类：
Configuration.cs如果我正确理解了Entity Framework，那么应该在应用新的数据库迁移文件后执行namespace SNS.Database.Migrations
{
public class Configuration : DbMigrationsConfiguration<SNSContext>
{
public Configuration()
{
AutomaticMigrationsEnabled = false;
}
protected override void Seed(SNSContext context)
{
...
}
}
}
方法。此外，要进行配置，请通过以下调用完成：
Seed工作正常。但是，即使我没有进行System.Data.Entity.Database.SetInitializer(new MigrateDatabaseToLatestVersion<SNSContext, Configuration>());
调用，也始终会调用Seed方法。
所以我的问题是，是什么告诉实体框架运行SetInitializer，为什么它总是执行Configuration.cs方法？
我已经检查了我的Seed文件，但没有指定codeConfigurationType。
