问题描述

我刚才下载的Visual Studio 14 CTP版，创造了Windows Phone的一个空白的应用程序。我试图打开 MainPage.xaml中和设计师展示了以下错误：

I have just downloaded the 14 CTP version of Visual Studio and created a blank app for Windows Phone. I tried to open the MainPage.xaml and the designer shows up the following errors:

和那些谁也看不出图像

System.Exception

我进入 App1.xaml.cs 和 MainPage.xaml.cs中和我见过的应用和的MainPage ，分别为，不必为的InitializeComponent）定义（。

I entered App1.xaml.cs and MainPage.xaml.cs and I've seen that App and MainPage, respectively, don't have a definition for InitializeComponent().

该项目是它是由Visual Studio中创建的状态，我没有改变任何东西！

这是怎么回事，我怎么能解决呢？

Why is this happening and how can I solve it?

推荐答案

确保您的XAML类名称匹配您的代码隐藏类的名称。 。我同时重构碰上这几次

Ensure the class name on your XAML matches the class name in your code-behind. I've run into this a few times while refactoring.

XAML开始标记：

<UserControl
    x:Class="Namespace.Foo"
    ... />

代码背后：

public sealed partial class Bar : UserControl
{
    public Bar()
    {
        // This will become the error specified (does not contain definition)
        this.InitializeComponent(); 
    }
    ...
}

所以Namespace.Foo需要在这里Namespace.Bar摆脱错误的。这应该如使用页而不是用户控件。
