编辑generic.xaml是否有效？

嗨拉尔斯，
编辑Generic.xaml应该在Blend中工作，我的问题很少：
1。您使用的是Windows8和Visual Studio的哪个版本？我建议在最新的Windows8 Release Preview和Visual Studio 2012 RC位上尝试该场景。
2。您是否有可能与我们分享一个小型的repro项目？
您可以通过Microsoft dot com的navits向我发送详细信息，我可以优先考虑这个问题。

Is editing of generic.xaml suppose to work?
lh
Hi Lars,
Editing of Generic.xaml should work in Blend, I do have few questions:
1. Which build of Windows8 and Visual Studio are you using? I would recommend trying the scenario on latest Windows8 Release Preview and Visual Studio 2012 RC bits.
2. Will it be possible for you to share a small repro project with us?
You can send me details at navits at Microsoft dot com and I can take a look at this issue on priority.
