Thanks for reply. We have tried reprpducing this issue locally with small application, but np success. If you want sample code I can send it you, please let me know your email as I can’t attach the code in this blog.

But errors are coming on production server, can we apply a lock on adding a value/ removing a value from dictionary as this might be coming becuase of concurrent users?

Thanks,
Konda Reddy.

I’m afraid I haven’t seen this problem before, and after a quick look through my code I’m at a loss to explain it. If you can send me a small code sample that reproduces the problem, I’m happy to have a look at it and see if I can work it out.

As an aside – you might want to consider using something like Chirpy (http://chirpy.codeplex.com/) or something like Ayende’s CSS controller approach (http://ayende.com/blog/13314/elegant-code-raccoon-blogrsquo-s-css-controller) rather than my approach – other solutions to this problem have been offered over the last couple of years.

This is wonderful solution, but not working correctly for us for CSS, JavaScripts.

we are getting below errors very often.

An item with the same key has already been added.

Please let me know solutions?
