Former C# programmer here, in my most recent job hunt I rewrote my resume. I talked more about the value I provided for my company/customer (what the code did) rather than how I wrote the code. I'd say my results improved significantly in terms of getting my foot in the door.
I do mainly C# at my current job, so it's pretty prominent on my resume; perhaps I'll try a rewrite and focus more on what I've done rather than how I did it. Sounds like a good idea.
