我有一个WPF应用程序，尝试使用打开表单时，的ShowDialog（），我得到这个奇怪的例外，下面一台机器上。 任何想法是什么问题呢？

我已经经历了同样的错误，问题是与Windows presentation基础字​​体缓存服务。它的缓存文件被莫名其妙地损坏。按照此MS知识库文章中的说明， http://support.microsoft.com/kb/937135 ，我能得到这个问题消失。

这既适用于3.0.0.0和4.0.0.0版本的缓存。

在我发现一篇文章，我刚刚停止并禁用该服务，我的WPF应用程序启动权了。我怀疑禁用它会显示WPF应用程序（这是够慢的话）下降导致缓慢，但有几台机器在外地有这样的伊苏斯之后，我禁用它，因为有没有问题。

I have a WPF application, when trying to open a form using ShowDialog(), I get this weird exception below on one machine. Any idea what the problem might be?

I've experienced this same error, and the problem is with the Windows Presentation Foundation Font Cache Service. Its cache file is somehow corrupted. By following the instructions in this MS KB article, http://support.microsoft.com/kb/937135, I was able to get the problem to go away.

This applies to both the 3.0.0.0 and 4.0.0.0 versions of the Cache.

Before I found that article, I had just stopped and disabled the service, and my WPF application started right up. I suspect disabling it will cause a slow down in displaying WPF applications (which is slow enough already), but after having several machines in the field have this issus, I disabled it and have had no problems since.
