标签'ViewModelLocator“不XML命名空间CLR命名空间存在：XXX [英] The tag 'ViewModelLocator' does not exist in XML namespace clr-namespace:XXX

问题描述

我已经试过许多其他的解决方案，没有任何成功。我有一个名为 ViewModelLocator 这是位于我的便携式类库类。它有一个属性叫的ViewModels ，这类型的百科< K，V>

I have tried numerous other solutions without any success. I have a class called ViewModelLocator which is located in my portable class library. It has a property in it called ViewModels, which is of type Dictionay<K, V>

然后，我有一款Windows Phone 8的项目引用便携式类库。我增加了以下到WP8的App.xaml：

Then I have a Windows Phone 8 project that references the portable class library. I added the following to the WP8 app.xaml:

<Application
    x:Class="Kaizen.WP8.Test.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
    xmlns:test="clr-namespace:Foo.Core.Portable.ViewModel;assembly=Foo.Core.Portable">
    <Application.Resources>

        <test:ViewModelLocator x:Key="ViewModelLocator">
            <test:ViewModelLocator.ViewModels>
                <test:SampleViewModel x:Key="sampleVM"/>
            </test:ViewModelLocator.ViewModels>
        </test:ViewModelLocator>
    </Application.Resources>
</Application>

当我按标签上的F12，其导航到我的PCL正确类或属性。这表明VS知道的对象，但是当我试图和建设，我收到以下错误：

When I press F12 on the tags, it navigates to the correct class and or property in my pcl. Which indicates that VS knows about the objects, but when I try and build, I receive the following error:

标签'ViewModelLocator'呢在XML命名空间
不存在'CLR命名空间：Foo.Core.Portable.ViewModel;装配= Foo.Core.Portable'。

The tag 'ViewModelLocator' does not exist in XML namespace 'clr-namespace:Foo.Core.Portable.ViewModel;assembly=Foo.Core.Portable'.

标签'SampleViewModel 不XML命名空间
存在'CLR命名空间：Foo.Core.Portable.ViewModel;装配= Foo.Core.Portable

The tag 'SampleViewModel' does not exist in XML namespace 'clr-namespace:Foo.Core.Portable.ViewModel;assembly=Foo.Core.Portable'.

任何人都可以请提供一些帮助？

Could anyone please provide some assistance?

[更新]
我引用MVVM光的PCL版本在我的PCL项目。这是 ViewModelLocator 类的样子：

public class ViewModelLocator
{
    public dynamic this[string viewModelName]
    {
        get
        {
            if (this.ViewModels.ContainsKey(viewModelName))
            {
                return this.ViewModels[viewModelName];
            }

            else
            {
                return null;
            }
        }
    }

    public Dictionary<string, ViewModelBase> ViewModels { get; set; }

    public ViewModelLocator()
    {
        this.ViewModels = new Dictionary<string, ViewModelBase>();
    }
}

我的WP8项目还使用了MVVM光的PCL组件。我注意到，如果我利用 ViewModelBase 类作为字典值，当我得到的错误。这是因为使用这两个项目之间的MVVM光PCL是一个问题？
[更新]

My WP8 project also makes use of the mvvm light pcl assemblies. I noticed that, if I make use of the ViewModelBase class as the dictionary value, that when I get the errors. It's as there's an issue using the mvvm light pcl between the two projects?! [Update]

在事先非常感谢！
亲切的问候，

Many thanks in advance!! Kind regards,

好了，所以我不完全相信我做错了什么在我的第一次尝试，但我重新创建解决方案，并进行或多或少相同的步骤，我没有再收到错误？ O_O

Okay, so I'm not exactly sure what I did wrong in my first attempt, but I recreated the solution and performed more or less the same steps and I didn't receive the error again?! o_O
