SA1200 How to suppress it for a few files (namespaces)?

Hi everyone, I meet this scenario when I try to disable rules for auto-generated files of EF Core. I can suppress a few other messages for the scope namespaceanddescendants, targeting migration files’ namespaces.

However, I cannot suppress SA1200 for some reasons (bug, or by design?).

Auto-generated code:

using System;
using Microsoft.EntityFrameworkCore.Migrations; // These 2 using statements throw warning

namespace My.Data.Migrations.Parent.Namespace
{
    ...
}

In my GlobalSupressions.cs file, I have:

[assembly: SuppressMessage(
    "StyleCop.CSharp.OrderingRules",
    "SA1200:UsingDirectivesMustBePlacedWithinNamespace",
    Justification = "Auto-generated by EF Core.",
    Scope = "namespaceanddescendants",
    Target = "My.Data.Migrations.Parent.Namespace")]

This does not work. I have also tried “member”, “resource”, “module”, “type”, “method”, “namespace”. Nothing works.

Moreover, the way that the document suggests is not really suitable for me because I don’t want to suppress the message for the whole assembly.

So, my question is that can we suppress SA1200 for files/namespaces? (and how?) Thank you all.

…A few new files…

Are these new files with new names, or do they overwrite files? Put another way, after the pragma lines are added, will the code generator ever overwrite the file and remove them?

If each file is only generated one time, my suggestion would be:

1. Fix SA1200 in the generated file rather than suppress it
2. File a bug for EF requesting that the code template honor the .editorconfig setting that instructs the IDE to place using directives inside namespaces

More of “repeatedly”. When the devs make changes to the database models, they run the CLI. A few new files (one is the example I gave above) will be generated. So, our current workflow after each CLI run like that is to go into the files and put #pragma warning disable to every file that is generated.

Using GlobalSupressions, I was able to suppress other warnings. The only left is SA1200.
