是什么导致 VS 2010 SP1 WPF 设计器崩溃? [英] What causes the VS 2010 SP1 WPF Designer to crash?

问题描述

在以下情况下，我们在 VS2010 WPF 设计器中的各种机器上遇到崩溃:

We're experiencing crashes on various machines in the VS2010 WPF designer in the following scenario:

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

要重现错误，请创建一个新的 WPF 解决方案，执行以下操作:

To reproduce the Error, create a new WPF Solution, perform the following actions:

• 创建新的 WPF 解决方案
• 打开主窗口，添加一个文本框，设置一些静态文本
• 添加对 FluentNhibernate.dll 版本 1.2.0.712 的引用
• 清理并重建解决方案
• 再次在设计器中打开主窗口，编辑文本
• 在设计器中，单击窗口左侧，然后再次返回文本框

没有数据/命令绑定，没有引用 FluentNHibernate 功能或任何高度复杂的代码，只是在 MainWindow.xaml 中具有以下 XAML 的新 WPF 解决方案:

There's no Data / Command Bindings, no code that references FluentNHibernate functionality or anything highly sophisticated, just a new WPF Solution with the following XAML in the MainWindow.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>

这是完整的 Stacktrace:

MS 已确认这是一个 SP1 错误，但为了获得令人满意的结果，我需要了解更多有关此问题的信息...

MS has confirmed this as a SP1 Bug, but for a satisfactory outcome, I need to understand more about the issue...

是什么原因造成的，为什么只有在添加 FNH 时才会出现这种情况，为什么只有在从某个位置添加它时才会出现(程序集相同 - 我们进行了逐字节比较)?没有 SP1，它可以工作...

What causes this, why does it occur only when addind FNH, why only when adding it from a certain location (assembly is the same - we did a bytewise comparison)? Without SP1, it works...

推荐答案

我们有时会通过添加来解决这个问题

We sometimes get around this by adding

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

在违规控件的加载事件中

in the loaded event of the offending control
