Usings before/after file-scoped namespace

Question

C# 10 gave us file-scoped namespaces. So this:

using Foo;
using Bar;
namespace Baz {
  // ...
}

can be written as:

using Foo;
using Bar;
namespace Baz;
// ...

There are differences between usings before and after a namespace. Does the compiler automatically reorder that to:

namespace Baz;
using Foo;
using Bar;
// ...

If not, is there a dotnet build or msbuild CLI switch, code analyzer or some other option to enable such a thing?

Add to your .editorconfig:

csharp_using_directive_placement = inside_namespace

An image says it all:

As you can see you can select which mode you want in Visual Studio (so it doesn't matter!).

'Options', 'Text Editor',' 'C#', 'Code Style'.

Thanks for this Poul, upvoted! I'm sure many would benefit. I'm not using VS though. (linux, cli, vscode.) – lonix Oct 14 '22 at 03:42
