使用<NetFx40_LegacySecurityPolicy> Element使我能够在Visual Studio 2010和2012 Windows窗体设计器中使用旧的.NET 2.0许可下的.NET 2.0控件，以便为TRAVERSE生态系统开发。 （见NetFx40_LegacySecurityPolicy in design-time mode。）
但是，同样的设置会强制Visual Studio 2013立即崩溃打开显示。 是否有解决方法，或者我是否被迫安装Visual Studio 2012以使用Forms设计器？
它调用Environment.FailFast，并显示消息“无法在UI线程上安排时间。延续将永远不会执行。”它捕获的异常，这是一个InvalidOperationException，消息“动态操作只能在同源AppDomain中执行。”
