将DataTemplates应用于Expression Blend中的样本/设计数据

我有一个ListView,它应该显示类Sensor的对象,为此我创建了一个简单的(现在)DataTemplate。

为了在Expression Blend中进一步设计这个DataTemplate,我从类as shown in the docs创建了样本数据(虽然我使用Blend for Visual Studio 2013,但它看起来是一样的。)

我可以成功地将我创建的示例数据显示在ListView中,但它没有使用我创建的DataTemplate,因为显示的元素似乎属于不同的"设计"名称空间:

  • 我班级的合格名称为Miotec.BioSinais.ModeloDomínio.Sensor;
  • (但)显示的类的限定名称为_.di0.Miotec.BioSinais.ModeloDomínio.Sensor

我做错了什么? (下面的代码和截图)
