new line option before/after the arrow when using an expression body for a method/property

[vsfeedback]

This issue has been moved from a ticket on Developer Community.

I want the option to add a new line before(or after) the arrow when using an expression body for a method (or property).

Currently, the following code using long type names will not break on a new line.
One line is too long.

public static System.Collections.Generic.IList<Guid> CreateList() => new  System.Collections.Generic.List<Guid>();

If possible, I would like to see a line break before(or after) an arrow.
(The first line is the same as in the block body!)

public static System.Collections.Generic.IList<Guid> CreateList()
    => new System.Collections.Generic.List<Guid>();

My editorconfig is below.

csharp_new_line_before_open_brace = all
csharp_new_line_before_else = true
csharp_new_line_before_catch = true
csharp_new_line_before_finally = true
csharp_new_line_before_members_in_object_initializers = true
csharp_new_line_before_members_in_anonymous_types = true
csharp_new_line_between_query_expression_clauses = true

Thanks.

Duplicate of #21631.

I found this open feature request when I googled how to do that exact thing, wrap the line before the arrow operator when using expression bodied methods. Later I discovered that ReSharper has a formatting rule like this, so if you use RS this might be a workaround for anyone waiting for this to be implemented in VS natively.

The RS rules are

[resharper_]csharp_wrap_before_arrow_with_expressions, [resharper_]wrap_before_arrow_with_expressions

You can also find them in Extensions > ReSharper > Options > Code Editing > C# > Formatting Style > Line Breaks and Wrapping > Arrangement of Expression Bodied Members

Hope this helps. Cheers.
