That doesn't tell us anything other than the problem happens when creating the notification service. You could have a missing key, there could be bad config somewhere, we can't tell until you give us stacktrace or more of the related code.

Please update your question rather than replying in comments, it make the Question harder for others to read.

Added stack trace Sir.

I'm afraid this is outside of my area of expertise, but it looks like the application is having problems loading the x509 certificate. You should check how this is loaded and research which steps you need to take. Hopefully someone will have a better answer.

You could take a look at this http://code.google.com/p/apns-sharp/issues/detail?id=47
I don't want to "answer" as it'll reduce the number of people more experience in this sort of stuff from seeing your question. Hopefully the resolution in the thread is what you need.

Thanks for the help sir but its still not working :(

Do not answer you own question like that! Its status switches away from "Unanswered" and it drops out of the Unanswered Q&A Secion, making it less visible to people who might help.

Solution 2

You're asking this question in the wrong place. You should be asking in Apple's Developer Support forum[^].

It's extremely unlikely anyone here is going to have any experiense with the library you're using.

Solution 3

I just fixed the same issue on my server setting the application pool identity (in advanced settings of the app-pool) to LocalSystem.
