如果我在Visual Studio 2010 SP1中创建一个新项目,并选择“WPF应用程序”,并尝试构建生成的应用程序,我会得到错误
名称“InitializeComponent”在当前上下文中不存在。
今天早上,当我试图构建当前项目时,我遇到了类似的错误。昨天,我编译和运行它没有问题。
我创建了一个新项目,每当我编译项目时,都会得到错误。我刚刚把项目发给了同事,他刚刚编译完成,没有任何错误。
怎么了?

导致这个错误的另一个常见原因是:
Right click on folder in project to create new UserControl. This creates a class and xaml file that derives from user control in the namespace of the folder. Then you decide to change the namespace of the class because you're really just using folders for organization of code. The x:Class attribute will not get automatically updated so it will be searching for a class that doesn't exist. Could probably use a better error message like "x:Class type could not be found in namesace bla.blaa.blaaa."
其他回答
在一些操作之后,.cs文件的命名空间和。xaml文件中的命名空间可能是不同的(在xaml中查找x:Class="namespace. yourtype ")。
使它们相同。
当我试图构建一个针对net48的SDK项目时,这种情况发生在我身上。它与MSBuild.exe一起工作很好,但dotnet构建失败与给定的错误。
对我有用的是
在<PropertyGroup/>节点中添加<UseWPF>true</UseWPF> 删除所有<Page />元素,因为它们现在已被自动包含。
现在msbuild和dotnet都可以构建了。

此问题的另一个解决方案是简单地将属性-> Build Action从嵌入式资源更改为其他任何内容,保存,然后将其更改为嵌入式资源。错误消失了。
我知道这是一个老问题了,但我们也遇到过类似的问题。我们能够使用VS2012构建一个项目,但不能从命令行使用msbuild。我进入。proj文件,并注意到它在默认的“PropertyGroup”部分下没有“ProjectTypeGuids”的记录,所以我添加了这个:
<ProjectTypeGuids>{60dc8134-eba5-43b8-bcc9-bb4bc16c2548};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}</ProjectTypeGuids>
这是WPF的项目GUID。然后我删除并重新添加UserControl,它开始工作。我不确定我是否必须做最后一步,但现在它对我有用。
I know this was answered due to a different cause, but this is a highly hit posting and I had ran into the same issue with a class library. In this case, it turned out to be both a change in my namespace (answered in this post here) and that the compiler could not rebuild the Window.g.i.cs which defines the InitializeComponent() method. It couldn't because the class library was missing the ProjectTypeGuid value for WPF projects in the csproj file. Instructions for this are here and here. I thought I would share in case someone else has run into the same issue. Just changing the namespace isn't enough in this case.
