ReSharper for Visual Studio Code also provides multiple formatting rules for attributes.
ReSharper helps you apply attributes style in the existing code and takes your preferences into account when it produces new code with code completion and performs refactorings.
Apply style preferences for attributes
By default, multiple attributes are checked for compliance with your preferences and if they do not comply, ReSharper for Visual Studio Code highlights such declarations and suggests the corresponding quick-fix.
Your preferences may say that the attributes should be in separate sections:

Configure preferences for attributes style
You can configure syntax style settings via EditorConfig. These settings can be stored in .editorconfig files on different levels of your solution hierarchy. The files are normally put under VCS so that settings defined there are shared among the project team.

Add the required attributes style properties to the file. For example:
