问题描述
这个错误一直在发生，但最近看起来它仍然存在。简而言之，我在Blend 4中打开的解决方案中的每个.xaml，我得到错误：
This error has been coming and going, but lately it looks like it's there to stay. In short, every .xaml from the solution that I open in Blend 4, i get the error:
"异常：错误HRESULT E_FAIL已从调用COM组件返回。
"Exception: Error HRESULT E_FAIL has been returned from a call to a COM component.

毋庸置疑，这意味着我无法在Blend的设计视图中工作。对于简单的"从头开始"而言，项目设计师工作，我没有得到错误。所以似乎项目中存在一些问题。
Needless to say, this means I can't work at all in design view in Blend. For a simple "from-scratch" project the designer works and I don't get the error. So it seems there's something in the project bugging it.
我知道如何找出问题所在吗？
Any idea how I can find out what the problem is?
