Run autofix across the entire solution

Is there a way I can run autofix across the entire solution, let’s say I want the this prefix to be applied to all the files in the solution.

@darrensteadman In Visual Studio, this is possible for the current document, project, or even entire solution (already from the very first release of VS with analyzers):

@sharwell Do you know of any oss tools out there that will run code fixers on an entire solution, as a command line tool?

Why was this closed? The question wasn’t answered.

Being able to run a command-line Roslyn tool to do codefixes e.g. on checkin would be incredibly useful - I’m not averse to building something like that myself, but obviously if there is already an official/recommended tool that does this, I’d prefer to use it. If not, the extension points that would be needed, or pointers in the right direction, would be very welcome - although I suspect the fact that MSBuildWorkspace is still MIA (see dotnet/roslyn#17974) will be a problem.
