Blend 4错误加载设计器：HRESULT E_FAIL [英] Blend 4 error loading designer: HRESULT E_FAIL

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?

 

推荐答案

有时这是由其中一个XAML资源文档中未解析的引用引起的（我刚刚在我的Generic.xaml中修复了一个未解析的引用，现在错误消失了）。你可以下载ReSharper，该工具应该指出XAML中的任何问题
。

Sometimes this is caused by unresolved references inside one of the XAML resource documents (I just fixed one of those unresolved reference inside my Generic.xaml and now the error is gone). You can download ReSharper and that tool should point out any problems inside the XAML.
