If it worked at runtime but not design-time then I am blaming VS 2010 for being buggy. I've had VS 2010 not recognize the local namespace when imported into XAML, but when opened in VS 2012 it worked in the designer with no problems. Unfortunately, Visual Studio 2010's XAML/WPF support is far from perfect. Expression Blend or Visual Studio 2012 are better.
如果它在运行时有效但在设计时无效，那么我将责怪 VS 2010 有问题。我让 VS 2010 在导入 XAML 时无法识别本地命名空间，但是在 VS 2012 中打开时，它在设计器中正常工作，没有任何问题。不幸的是，Visual Studio 2010 的 XAML/WPF 支持远非完美。Expression Blend 或 Visual Studio 2012 更好。
I did like ViktorLaCroix 's suggestion. I would try
我确实喜欢 ViktorLaCroix 的建议。我会尝试

Instead of importing it using clr-namespace and see if that helps you. That's how I am using it and it works fine. I'll also show you my reference details for the library.
而不是使用 clr-namespace 导入它，看看是否对您有帮助。这就是我使用它的方式，它工作正常。我还将向您展示我对该库的参考详细信息。
