I'm using VS2010, and I've download the [C# POCO Entity Generator](http://visualstudiogallery.msdn.microsoft.com/en-us/23df0450-5677-4926-96cc-173d02752313) and installed it, now I want to use it.

I can't read the [toturial](http://go.microsoft.com/fwlink/?LinkId=180359) 1 and I can't find any other good toturials, so I've had a go myself - I have created a model and then I'm creating new POCO Entity, but I got the bellow error:

```

```

What is the problem? I think it can't find the model mapping, if this is the case, how do I resolve this?
