ssis - 为什么 BIML ScriptTask 会失败，直到我在 VS 中打开脚本并保存包

Question

我有这个 BIML 脚本，它创建一个主包和子包。子包中有一个 ScriptTask，它将父包变量的值映射到子包变量。当我在 SSIS(Visual Studio 2015，目标 Sql Server 2014)中生成包时，它们生成得很好。如果我运行主包，子包将失败并出现以下错误:

DTS Script Task has encountered an exception in user code:
Project name:  ST_GetJobLogIdHere
Exception has been thrown by the target of an invocation.

at System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments, Signature sig, Boolean constructor)
at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object[] parameters, Object[] arguments)
at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)
at System.RuntimeType.InvokeMember(String name, BindingFlags bindingFlags, Binder binder, Object target, Object[] providedArgs, ParameterModifier[] modifiers, CultureInfo culture, String[] namedParams)
at Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTATaskScriptingEngine.ExecuteScript()

当我在子进程中打开 ScriptTask，然后再次关闭它时，包是脏的，所以我保存它。之后，运行包就可以正常工作了。

这是 BIML 脚本:

我错过了什么？为什么在我手动打开代码窗口之前包会失败？ 在此先感谢您的帮助， 西蒙

阅读上面的评论以澄清问题。

事实证明，Visual Studio 2015 中的 BIML Express/BidsHelper 不知道项目属性中设置了哪个 SQL Server 目标版本。

解决方案是安装 VS2013/SSDT 2014 和 BIML Express for VS2013，以便能够正确生成 SSIS 2014 包。

VS 2015/SSDT/BIML Express 将仅生成 SQL Server SSIS 2016 包的脚本任务。
