让 XAML 设计器在 VS2010 中展示设计

Question

我开始学习 WPF，我将 Family.Show 项目作为一个真实示例来帮助我学习。它有一个相当不错的用户界面，并且家谱主面板中有一些很酷的动画——我很想看看他们是如何做到的。

于是我下载了源代码（http://familyshow.codeplex.com/releases/view/23637#DownloadId=59428），在VS2010 Professional中打开了3.0的解决方案，让它做转换......试图打开 MainWindow.xaml 然后得到：

Error   1   Undefined CLR namespace. The 'clr-namespace' URI refers to a namespace 'Microsoft.FamilyShow' that is not included in the assembly. C:\Users\nloding\Documents\Visual Studio 2010\Projects\Family.Show-3.0\FamilyShow\MainWindow.xaml   7   15  FamilyShow
Error   2   The type 'local:DiagramViewer' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built. C:\Users\nloding\Documents\Visual Studio 2010\Projects\Family.Show-3.0\FamilyShow\MainWindow.xaml   118 12  FamilyShow

Error   8   The type 'local:OldVersionMessage' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built. C:\Users\nloding\Documents\Visual Studio 2010\Projects\Family.Show-3.0\FamilyShow\MainWindow.xaml   143 8   FamilyShow

设计师什么也没展示。我已经验证了对 FamilyShowLib 项目的引用——我什至构建了 DLL 并将其添加到主项目中。这解决了其他一些小错误，但就是这样。我还必须重新添加对 PresentationCore、PresentationFramework 和 WindowsBase 的引用。现在我只是坚持以上。

所以我在 Google 上搜索了一下，发现 VS 中的 XAML 设计器不起作用。这看起来很奇怪，但也许这就是问题所在。

我怎样才能让它发挥作用，这样我才能真正学习 WPF?!?!?

Answer 1

我不确定您通过 Google 找到了什么，但 VS 2010 XAML 设计器确实有效。您收到的错误表明您缺少对包含 Microsoft.FamilyShow 命名空间的程序集的引用。

检查您的 References 文件夹，确保列出的所有引用旁边都没有黄色标记，表示缺少程序集。在尝试查看设计器之前，您可能还需要构建项目。

更新：

我下载了项目并转换为 VS 2010。由于一些构建警告，我不得不手动设置 Familylib 项目以编译为 .NET 3.0（右键单击项目，打开属性）。然后项目构建没有错误，我能够在设计器中查看 MainWindow.xaml。
