Suggestion to Align Default Namespaces with eShop.* Pattern for Better VS Integration

I would like to bring to your attention that some projects within the repository, such as Basket.API, do not follow the eShop.* naming convention for default namespaces. Here are the details and a suggestion for improvement:

**Current Namespace Configurations**
- Example: The Basket.API project, among others, does not align with the common eShop.* pattern. This inconsistency is depicted in the attached screenshot.

- Impact on Visual Studio Integration
Description: This variance in namespace naming can complicate the automatic syncing process with Visual Studio, potentially impacting development flow and consistency.

It would be beneficial to standardize the namespaces across projects to the eShop.* pattern. If the team finds it helpful, I'm more than willing to assist by contributing a pull request to make this adjustment.
