I have an .net 4.5 application that works just fine locally but when I try and deploy it as an IIS application it has some bugs. I never receive error messages but the functionality isn't the same. I have tried to use VS and debug by attaching to process but I am unable to get any kind of feedback at all of what is going on. Is there another way to debug the deployed application?
Attaching it to the process of that application pool is your best bet for something like this. Make sure debugging is on in the web.config, or you will not get any proper results.
Are you trying to debug your application on your local IIS or your some production server hosted somewhere else?
I have a production server that is hosted somewhere else...
I know that this is very vague instructions for help but since debugging doesn't work but - if we were to just brainstorm - what is normally the case when this happens?
