Getting dizzy using the Spec Explorer Modelling Guidance

While creating a sample Spec Explorer application, you have this feeling of being lost. The thing is if you follow the steps of the Modeling Guidance (using the "Author a model from scratch" option), you'll soon get lost since the steps and the sample code are not consistent and continuous.

Spec Explorer - Visual Studio Encountered An Exception

While I was playing around with Spec Explorer and I hit this error:

After this, very simple IDE operations like Copy/Paste are not working. I have to restart Visual Studio 20101 Beta 2. It's getting a little bit frustrating.

And the thing is, once the above error was encountered you have to close Visual Studio 2010 using the Task Manager since closing it using it's own window is of no use since you'll keep on seeing this again and again:

Missing "ADO.NET Entity Data Model" Template in Visual Studio 2010 Beta 2 Ultimate Edition

When I installed the Microsoft Visual Studio 2010 Beta 2 Ultimate edition, I wanted to know how the ADO.NET Entity Data Model can make me forget my good experience with LINQ To SQL. Unfortunately after much searching, I can't seem to find a way to add it to my project, whether it's a web project or a windows application I'm working on.
