XAML解析例外 - 的xmlns：X =" HTTP：//schemas.microsoft.com/winfx/2006/xaml"

问题描述

我是工作在我的电脑昨晚WPF项目，使用VS 2010旗舰版。

I was working on a WPF project on my PC last night, using VS 2010 Ultimate.

我刚才跟VS C＃2010速成打开了它在我的上网本。

I have just opened it up on my Netbook with VS C# 2010 Express.

当我尝试运行它，它，我抛出的XAML解析异常，它告诉我，该行：

When I try to run it, it I am thrown an XAML Parse Exception which tells me that the line:

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

时的问题。我看不出有问题吧，我从来没有改变过它，它看起来是它应该是什么

Is the problem. I can't see a problem with it, I have never changed it and it looks like it is what it should be.

错误：

'The invocation of the constructor on type 'WpfApplication1.MainWindow' that matches the specified binding constraints threw an exception.' Line number '3' and line position '9'.

推荐答案

XAMLParseException是WPF中抛出一个共同的异常。不幸的是不是非常有帮助。

XAMLParseException is a common exception thrown in WPF. Unfortunately it isn't very helpful.

要帮助找出真正的错误是什么，您可以打开的异常在Visual Studio早得多报告。默认组合键Ctrl + Alt + E。在那里，检查所有的箱子。

To help find out what the real error is, you can turn on exception reporting much earlier in Visual Studio. Default key combination is Ctrl + Alt + E. From there, check all the boxes.

现在是在你的代码抛出的异常将在调试器中突出显示。

Now the exception that is thrown in your code will be highlighted in the debugger.
