There are a million links like this one http://blogs.msdn.com/b/cie/archive/2014/01/24/windows-azure-remote-debugging.aspx, which more or less would seem to take care of the remote debugging setup. I have done this many times in VS 2013 Update 2, deployed, then attached to debugger and it simply does not work. Well, the debugger seems to attach, but I continually get the message when I hover over a break point informing me that 'The breakpoint will currently not be hit. No symbols have been loaded for this document' A while back I recall seeing a channel 9 presentation and they seemed to configre the symbol store. I tried configuring this and it still gives me the same message when hovering over the breakpoint.
VS 2013 Update 2 Remote Debugging - I can only get it to work with a 'Debug' build. I have set the Debugging Option "Enable Just My Code" and loaded all symbols -- this seems to work fine. I can now set breakpoints and do not receive the message you (and I) noted earlier.
This is probably not the ideal situation as it would be nice to be able to attach the debugger to a production release but it seems to be a semi-reasonable workaround for now.
EDIT: Important points:
- You must enable Remote Debugging in the Azure Portal for your Cloud Service or Web Site -- Configure Tab (it only remains enabled for 48 Hours)
- The debug attribute of the compilation element in your Web.config file must be set to "true". This means, you either have to do a 'Debug' build or manually edit the Web.config file. Here is a link to official Microsoft documentation with a full explanation and a great example of how to do that without redeploying your application: http://azure.microsoft.com/en-us/documentation/articles/web-sites-dotnet-troubleshoot-visual-studio/#remotedebug
- If you still have problems you may have to disable the Debugging Option Enable Just My Code in Visual Studio
I had the same problem - also with VS 2013 Update 2.
The crucial bit I missed was selecting the w3wp.exe process in the pop-up that shows the running processes before hitting the Attach button.
