Scoped usings inside namespaces

[KlausEvenEnevoldsen]

I love global using but sometimes the scope of the entire project is too much. Often I have a folder named Data where I store all my stuff that uses EntityFramework. It would be so nice to be able to create scoped usings inside a namespace like this:

namespace using Microsoft.EntityFrameworkCore;
using System;

namespace Data;

public class Foo
{
  // stuff
}

All namespaces below Data now has access to the classes inside Microsoft.EntityFrameworkCore.

There is something similar in ASP.NET, where the _imports.razor file works for the current branch of the file system and below. Something like that could work, I guess?
