Expression Blend:收到错误"XXX"在名称空间"XXX"中不存在，但在VS2008中不存在 [英] Expression Blend: Getting error "XXX" does not exist in the namespace "XXX", but not in VS2008

问题描述

我正在尝试使用Blend 3.0编辑包含某些WPF控件的项目.该项目已经可以在Visual Studio 2008中编译并正常运行.

I am trying to use Blend 3.0 to edit a project that contains some WPF controls. This project already compiles and runs fine from Visual Studio 2008.

但是，在Blend中，我收到了毫无意义的神秘错误:

In Blend however, I'm getting mysterious errors that make no sense:

例如，我有一个派生自Control的类:

For example, I have a class that derives from Control :

namespace Company.WPFControls.SearchTextBox
{
    public class SearchTextBox : Control
    {
        ...
    }
}

然后我尝试在同一程序集中的资源中使用它来分配样式:

And I try to use it in a resource, in the same assembly, to assign a style:

<ResourceDictionary 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
    xmlns:local="clr-namespace:Company.WPFControls.SearchTextBox" 

    <Style TargetType="{x:Type local:SearchTextBox}">
        ...
    </Style>
</ResourceDictionary>

在Blend中出现以下错误:

I get the following error in Blend:

名称"SearchTextBox"不 存在于命名空间中 "clr命名空间:Company.WPFControls.SearchTextBox".

The name "SearchTextBox" does not exist in the namespace "clr-namespace:Company.WPFControls.SearchTextBox".

我尝试通过添加;assembly=Company.WPFControls来指定程序集名称，但它不能消除错误.

I've tried specifying the assembly name, by adding ;assembly=Company.WPFControls but it doesn't remove the error.

有什么办法可以解决此问题，或者至少可以找出问题的根源?

Is there any way to fix this or at least figure out where the problem comes from?

推荐答案

在Windows Vista 64上，我在Blend 2上遇到了同样的问题.

I had the same problem with Blend 2, on a Windows Vista 64.

我通常在VS2008中编译我的解决方案，并在所有项目中使用"Debug-x86"目标，以便它与其他一些仅32位的项目兼容.

I normally compile my solution in VS2008, with a "Debug - x86" target on all my projects, so that it's compatible with some other 32 bits-only projects.

Blend似乎喜欢调试-任何CPU"目标. 我基本上改变了配置管理器，使其针对任何CPU平台而不是x86.

It looks like Blend loves the "Debug - Any CPU" targets. I basically changed my configuration manager so that it targets Any CPU platforms instead of x86.

所以...

• 在Blend和VS2008中打开您的解决方案
• 在VS2008中，选择菜单Build-> 配置管理器
• 确保您的解决方案 配置具有调试-任何CPU" 适用于所有项目
• 在VS2008中编译
• tadaaaa 您的Blend项目应更新并删除这些错误... 对我来说很好

• Open your solution in Blend and in VS2008
• In VS2008, choose the menu Build -> Configuration Manager
• Ensure that your solution configuration has a "Debug - Any CPU" for all projects
• Compile in VS2008
• tadaaaa Your blend project should update and remove those errors... well it did for me

我做了相反的工作来验证它是否确实如此，看来是的……我只是将解决方案更改恢复为Debug-x86，清理了所有内容，然后重新构建，而我仍然返回错误消息"Does不存在[...]"

I did the opposite to verify if it was really that, and it seems yes... I simply reverted the solution changes back to Debug - x86, cleaned everything, and rebuilded, and I was still back with the error "Does not exist [...]"

至于为什么?" ...我不知道，但至少现在可以了！

As for the "Why?"... I don't know, but at least it works now!
