How to automatically reorder named function arguments with Resharper?

Question

When reordering arguments in a function signature, callers do not get updated (unless specifically using the Change signature method in Resharper) and continue to compile fine with the old order. This is not a problem semantically but may look a bit messy when many callers end up having different argument orders.

Is there any way with Resharper - or any other tool - to automatically reorder named parameters solutionwide so that they can perfectly match the function signature?

This seems like a nice refactoring function that would make the code look more consistent, and to which I don't see any possible side effect or negative aspect, much like standardizing other cosmetic aspects across a solutions.

Have you tried the "Change signature" refactor option on the method name? It will fix callers, as long as callers are in the same solution. — Lasse V. Karlsen

I know, but I am looking for a way to do this automatically for all functions in the solutions, which would take time if I had to do it manually (thousands of functions spread across many files). — Erwin Mayer

@LasseV.Karlsen obviously he has, since it's right there in the post. — sehe

Did you know Ctrl-F6 is the usual shortcut for Change Signature?
Did you know you can write R# plugins? Likely, this would not be a very large task
- see e.g. http://www.jetbrains.com/resharper/plugins/index.jsp

Might have some drawbacks too:

Ordering of parameters often conveys information to the developer: it might show some logical grouping of information, e.g.

 Foo(foo: 3,
     zyx: "hello",
     flurb: null,    // these 3 from the config file

     val: 42);       // from the input xml

Why would it be a bad idea to ensure callers use named arguments in the same order as in the original function signature? I am not talking about renaming parameters per se, if this is what you feared. Thanks for the 2 suggestions though.

Would you believe I missed that in the title? Anyways, edited
