Surface Simulator抛出“指定的强制转换无效”。例外 [英] Surface Simulator throws "Specified cast is not valid." exception

问题描述

嗨！

我们正在几台PC上开发Surface应用程序（Win7 x64，VS2008和VS2010）。由于在这些PC上运行WPF4触摸应用程序，Surface Simulator不再起作用。

它抛出"指定的强制转换无效"。启动期间的异常。

   at System.Windows.Threading.ExceptionWrapper.TryCatchWhen（Object source，Delegate callback，Object args，Boolean isSingleParameter，Delegate catchHandler）

  在System.Windows.Threading.Dispatcher.WrappedInvoke（委托回调，Object args，Boolean isSingleParameter，Delegate catchHandler）

这个问题有一个已知的解决方案吗？

解决方案

x64机器上不支持表面模拟器。你在32位机器上也有这个问题吗？

谢谢！

Hi!

We're developping Surface applications on several PCs (Win7 x64, VS2008 and VS2010). Since running WPF4 touch apps on these PCs the Surface Simulator doesn't work anymore.

It throws an "Specified cast is not valid." exception during start-up.

The stack trace is:

   at System.Windows.Application.RunInternal(Window window)
   at System.Windows.Application.Run(Window window)
   at System.Windows.Application.Run()
   at Microsoft.Surface.Simulator.SimulatorMain.Main()

Is there a known solution to this problem?

Thanks,

Helge ;-)=)

解决方案

The surface simulator is not supported on x64 machines. Do you have this issue on 32 bit machines as well?

Thanks!
