Developing calculation views in developer mode

Hello,

Until now we used the modeling perspective for developing Calculation views.

We would like to use Developer perspective.

Which kind of project should we use? 

XS project is more for XS development.- We saw that Calculation views are available as an object but we are not sure it is the correct project type.

Is there a special project type for modeling?

We are in SP10

Thanks,

Amir
