Hi Tim,

Can you try to create a product/product depending on your needs as described in the respective article:
- http://docs.sitefinity.com/for-developers-create-products
- http://docs.sitefinity.com/for-developers-create-product-types

I hope this helps.

I started from that example.

In-house we use dependency-injection extensively and need to Mock classes to support testing, we follow TDD as a standard development paradigm.

Did you ever solve this Tim? Unit tests in a Sitefinity project seem to be pretty problematic. I'm getting the same exception on Telerik.Sitefinity.Taxonomies.TaxonomyManager.GetManager().

Hi Arno,

For some managers we managed to use the constructor that took a parameter which we had mocked, we use Moq normally. However in not all cases was this successful/possible.
