Determine the necessary editorconfig to allow enabling IDE0055

[belav]

The rules under C# Formatting Options appear to all be unnecessary when using CSharpier and can cause conflicts.
The rules under .NET Formatting Options could still be useful.

It would be useful to determine what set of .editorconfig options would allow enabling IDE0055, or provide alternatives for the .NET Formatting Options

[elovelan]

This is what I've come up with so far. I'm still looking to see if there are non-IDE0055 options that are conflicting as well. These can be set to ignore if desired, but having the editor's help pre-save seems valuable. Also, I think I could write test(s) that leverage the analyzer to ensure this is correct (likely similar for R# settings).

I can't yet figure out if there's any way to control alignment via EditorConfig.

Also, these seem to be the only (documented) IDE0055 settings that aren't applicable:

dotnet_sort_system_directives_first = true
dotnet_separate_import_directive_groups = false

[elovelan]

There are also some experimental settings that may be applicable that Visual Studio seems to know about (at least in the preview version, I haven't checked the RTM version yet) that I have yet to investigate since they're undocumented.

Thanks for digging into this. I tested it out on a large repo and ran into a couple things.

With csharp_new_line_before_open_brace = all

It is unhappy with braces being on the same line as a ) in some cases

    public void Method(
        string someLongName
    ) { }

    if (ex is HttpRequestException) { }

    // this is fine
    public void Method() { }

Switching to csharp_new_line_before_open_brace = none causes a lot more complaints.

It is also unhappy with this statement

return from prp in this.DataProvider.LinqQuery<ProductRelatedProduct>()
    join p in this.GetTable() on prp.RelatedProductId equals p.Id
    where
        prp.ProductId == productId
        && prp.SystemListValue.Name == type
        && p.ActivateOn < DateTimeProvider.Current.Now
        && (p.DeactivateOn ?? DateTimeOffset.MaxValue) > DateTimeProvider.Current.Now
    select p;

// it wants
return from prp in this.DataProvider.LinqQuery<ProductRelatedProduct>()
       join p in this.GetTable() on prp.RelatedProductId equals p.Id
       where
           prp.ProductId == productId
           && prp.SystemListValue.Name == type
           && p.ActivateOn < DateTimeProvider.Current.Now
           && (p.DeactivateOn ?? DateTimeOffset.MaxValue) > DateTimeProvider.Current.Now
       select p;

I didn't see any way to disable or ignore either of these. And I'm not sure if we want to make the changes to get IDE0055 happy, but if #661 is implemented, and also puts System first, then it may not be necessary to figure this out. We've started enforcing sorted usings at work, and having CSharpier do it for me would make life a bit easier
