Using 3D OBJ file in Blend 2015

Question

I just started to lean WPF 3D and follow the tutorial. I created a 3D Model and exported it as OBJ file. Created a new WPF project and added this OBJ file. How I can use it inside Window or Viewport3D ? I found a link from Microsoft at: Import 3D content but it written for Expression Studio and there's no 'Insert' option in Blend :( I could not drag it on Window because of 'disabled' icon when dragging

When I double click on OBJ file I can see my 3D Model in WPF window - so I guess that WPF could read this file.

P.S. Here is Blend showing my 3d Model:

I have the same problem, Luckily I still have VS2010 and VS 2013 on my computer, and their Blend counterparts. My work around is to open my project in blend 2013 ,import my models , save then re-open in 2015, or start the project in one of the older Blend programs import the models then continue the program in 2015.
