Control from WPFToolkit doesn't exist in namespace
提问by cadi2108
I added to references WPFToolkit.dll and I added do my .xaml file following line:
我添加到引用 WPFToolkit.dll 并添加以下行执行我的 .xaml 文件：
xmlns:toolkit="clr-namespace:Microsoft.Windows.Controls;assembly=WpfToolkit"
and before following line:
在以下行之前：
xmlns:toolkit="http://schemas.microsoft.com/wpf/2008/toolkit"
In both cases in line
在这两种情况下
<toolkit:NumericUpDown Value="10" Increment="1" Maximum="10" Minimum="0" />
I have error:
我有错误：
Error 1 The tag 'NumericUpDown' does not exist in XML namespace 'http://schemas.microsoft.com/wpf/2008/toolkit'. Line 20 Position 18. C:\Users\Diament\Documents\Visual Studio 2008\Projects\MyBasicFlyffKeystroke\MyBasicFlyffKeystroke\Window.xaml 20 18 MyBasicFlyffKeystroke
错误 1 XML 命名空间“http://schemas.microsoft.com/wpf/2008/toolkit”中不存在标记“NumericUpDown”。第 20 行位置 18. C:\Users\Diament\Documents\Visual Studio 2008\Projects\MyBasicFlyffKeystroke\MyBasicFlyffKeystroke\Window.xaml 20 18 MyBasicFlyffKeystroke
Where is the problem? :(
问题出在哪儿？:(

Note: Consider the Extended WPF Toolkit - Numeric Up Down, is obsolete. And they strongly suggest to use any of "specialized" versions. This, by the way, shouldn'tgenerate an Error, but Warning.
注意：请考虑扩展 WPF 工具包 - Numeric Up Down已过时。他们强烈建议使用任何“专业”版本。顺便说一下，这不应该生成Error，而是Warning。
What about not finding the assembly, check your project's and Wpf Toolkitversions compatibility.
找不到程序集怎么办，请检查您的项目和Wpf Toolkit版本兼容性。

NumericUpDown is not part of the basic WPF Toolkitbut part of the Extended WPF Toolkit
NumericUpDown 不是基本 WPF 工具包的一部分，而是扩展 WPF 工具包的一部分
Use the IntegerUpDown (or any of the provided derived classes) and be sure to use the appropriate DLL in your application. Here is an example using the IntegerUpDown when the Extended WPF Toolkit DLL (Xceed.Wpf.Toolkit.Dll) is referenced by your project:
使用 IntegerUpDown（或任何提供的派生类）并确保在您的应用程序中使用适当的 DLL。这是当您的项目引用扩展 WPF 工具包 DLL ( Xceed.Wpf.Toolkit.Dll)时使用 IntegerUpDown 的示例：
<Window x:Class="WpfApplication4.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:toolkit="http://schemas.xceed.com/wpf/xaml/toolkit"
Title="Window1" Height="300" Width="300">
<Grid>
<toolkit:IntegerUpDown Value="10" Increment="1" Minimum="0" Maximum="10" />
</Grid>
</Window>

I had the exact same problem.
我有同样的问题。
If I skippedthe unblock step and simply unzipped, the xaml preview window would not load and VS would keep giving me the 'IntegerUpDown component does not exist in the namespace http://schemas.xceed.com/wpf/xaml/toolkit' error, even though auto-complete would happily list all the components in that namespace.
如果我跳过取消阻止步骤并简单地解压缩，则 xaml 预览窗口将不会加载，并且 VS 将继续向我提供“名称空间http://schemas.xceed.com/wpf/xaml/toolkit中不存在 IntegerUpDown 组件”错误，即使自动完成很乐意列出该命名空间中的所有组件。
However if I unblockthe zip file first, then extract, then reference the dll in VS, it all works correctly.
但是，如果我先取消阻止zip 文件，然后解压缩，然后在 VS 中引用 dll，则一切正常。
TL;DR:follow the installation instructionsexactly, particularly unblockingthe zip file first.
TL; DR：按照安装说明完全相同，尤其是疏导，首先把ZIP文件。

I've followed @Andrew suggestion (download, unblock, extract, add), but still had the same issue.
我遵循了@Andrew 的建议（下载、解锁、提取、添加），但仍然有同样的问题。
Instead, the install through the NUGET (follow the instructions on their page here) made it work without the need to do the manual steps.
相反，通过 NUGET 安装（按照此处页面上的说明进行操作）使其工作而无需执行手动步骤。

我发现了同样的错误。您必须卸载当前的安装工具包并重新安装工具包，它会解决错误。这不是一个正确的解决方案，但您可以继续工作。
