Applying DataTemplates to Sample/Design Data in Expression Blend

Question

I have a ListView that is supposed to display objects of class Sensor, for which I created a simple (for now) DataTemplate.

In order to further design this DataTemplate in Expression Blend, I created Sample Data from Class as shown in the docs (although I am using Blend for Visual Studio 2013, but it seems to be the same).

I can successfully get the Sample Data I created being displayed in a ListView, but it is not using the DataTemplate I created, since the elements displayed seem to belong to a different, "design" namespace:

• The qualified name of my class is Miotec.BioSinais.ModeloDomínio.Sensor;
• (But) the qualified name of the displayed class is _.di0.Miotec.BioSinais.ModeloDomínio.Sensor.

What am I doing wrong? (code and screenshot below)
