Code Inspection: Namespace does not correspond to file location
By default, ReSharper assumes that the namespace each class appears in matches its location in the project. The ‘root’ namespace for the project is defined in the project properties:
As a result of the above, all code elements at the project level are expected to appear in the
namespace, and a warning will be issued otherwise.
Namespaces are made deeper with the introduction of folders. A folder called
will necessitate all items it contains to appear in the
namespace. This can, however, be
circumvented in cases where you do not need the folder to append extra namespace elements. To avoid this, select
the folder and open its properties. Then, set Namespace Provider to False.
The folder will no longer influence the namespace of elements it contains, and ReSharper will not issue suggestions accordingly.
