是什么原因导致的VS 2010 SP1 WPF设计器崩溃？(What causes the VS 2

我们正在经历的在以下情形VS2010 WPF设计各种机器崩溃：

• 安装VS 2010 SP1
• 64位Windows 7
• 参考NHibernate.dll（版本1.2.0.712）

重现错误，创建一个新的WPF解决方案，执行以下操作：

• 创建一个新的WPF解决方案
• 打开主窗口，一个文本框添加到它，设置一些静态文本
• 添加引用FluentNhibernate.dll，版本1.2.0.712
• 清洁并重新生成解决方案
• 在设计师再次打开主窗口，编辑文本
• 在设计中，单击左侧窗口中，然后再返回到文本框中再次

没有数据/命令绑定，没有代码引用FluentNHibernate功能或任何非常先进的，只是一个新的WPF解决方案与在MainWindow.xaml以下XAML：

<Window x:Class="testWpfApplication2.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Width="800"
    Title="MainWindow" Height="350" >
  <Grid>
    <TextBox Text="yxcydfdssdfsdfdsfsdsddsasdyxcasd"  />
  </Grid>
</Window>

下面是完整的堆栈跟踪：

MS已经确认这是一个错误SP1，但对于一个令人满意的结果，我需要更多地了解这个问题...

是什么原因导致这一点，只有当addind FNH，从特定位置加入为什么只有当它（组装是相同的 - 我们做了一个比较，按字节），为什么会出现？ 不带SP1的，它的工作原理...

Answer 1:

我们有时会解决这个问题通过增加

if (System.ComponentModel.DesignerProperties.GetIsInDesignMode(this))
                return;

在有问题的控制的加载事件
