Debug high iis worker process

Question

I have a high iis worker process attached to a site, cpu hits 99% and stops the site. Ive been looking at the official guide at http://www.iis.net/learn/troubleshoot/performance-issues/troubleshooting-high-cpu-in-an-iis-7x-application-pool but a bit over my head.

My site is a asp.net website (not compiled), is there a third party tool capable of telling me which page/line of code the app is hanging on?

Thanks

If you're using Visual Studio 2015 the tools you're looking for are built into the IDE.

https://msdn.microsoft.com/en-us/library/mt210448.aspx

If you're not using that another way will be to use Debug Diag.

You'll find how to instructions on each of these tools, just by doing google searches. But I believe these tools will point you in the right direction and help you fix the CPU issue.
