I do like having the namespace there, if only to gently nudge you towards better architecture. As a temp fix I have overridden Rider's code formatting to not indent within the namespace, but C# 10 will bring file scoped namespaces. You can just declare the namespace between the imports and the classes, and everything in the file will be namespaced automatically.
