Hi Ronny and Jean,
Thank you for contacting us.
The visual studio template for creating a sample module is currently discontinued as we are preparing a slightly different strategy for creating your custom modules. At this point we can provide you with a few custom modules as part of the Software Development Kit. You can take a look at the Products module which is an advanced heavily customized Sitefinity module. Furthermore you can follow Josh Morales' blog post series
on how to create a Sitefinity based content module that is similar to what you were able to achieve using the template. However most of the feedback we had about the template is that it just outputs a few classes and configurations in which it is hard to learn or understand what is going on without having a robust step by step guide.
In our roadmap we have announced a new module builder tool
that allows users to create new modules (and hence content types) through user interface, inheriting core CMS features such as workflow, permissions, etc. on demand.
Thank you for your understanding and please let me know if you need further information.
