Visual Studio在编译期间编译WPF应用程序两次

Question

我在编译期间编译了两次VS2008中的WPF应用程序。两个CSC命令行类似，但有一些差异。第一个CSC命令行没有/resource选项，第二个在命令行上有两个/resource选项。

第二CSC命令行有这些额外的参数：

/resource:"obj\Debug AutoCAD\VisualApp.g.resources" /resource:"obj\Debug AutoCAD\CAP.Visual.Properties.Resources.resources" 

我恨张贴这样一个巨大的丑陋的编译器的输出，但这里有两个命令行。

任何想法可能会导致这种情况？我认为这是造成problem I posted about earlier today。

Answer 1

我注意到它并不总是出现在WPF项目中，只有在XAML中引用了XAML文件所属的程序集的名称空间时！在这种情况下，您需要两个编译步骤是有道理的，因为对于XAML-> BAML编译步骤，它需要引用程序集，所以它首先需要在汇编程序集中的元素之前构建程序集。

1. 创建一个名为WpfApplication1 WPF应用程序

2. 添加一个名为的UserControl1

3. 在MainWindow.xaml用户控件，添加 “的xmlns：我= CLR命名空间：WpfApplication1” 并插入UserContro1l在XAML中加入 到

4. 编译并在输出中看到有两个编译步骤， 首先是一个临时项目。

（见http://social.msdn.microsoft.com/Forums/en/msbuild/thread/3a52c962-187d-4701-9967-e0d25eb3b897一个问题，临时项目不读.csproj.user文件）

Answer 2

大部分推理两个阶段的汇编这里描述：

Building a WPF Application (WPF)

http://msdn.microsoft.com/en-us/library/aa970678(v=vs.110).aspx

不是人l标记编译的第1遍期间编译XAML页面。具有本地定义的类型引用的XAML文件（引用同一项目中其他位置的代码中定义的类型）在此时可免于编译。

不幸的是，大型项目的两阶段编译可能会对编辑/构建/调试工作流程有显着的性能影响，从而影响软件开发。我想尽可能地将非xaml保留在WPF/xaml项目之外是有意义的，所以不需要通过csc.exe来完成大量的重复工作。否则，感觉像Visual Studio 2013构建正在执行非常缓慢（并且它几乎让人考虑回到Windows窗体，VB 6甚至FoxPro）。
