For the 70-515 .NET 4 web certification there is a chapter on debugging your web projects. This is a pretty useful thing to know about. In fact the last chapter I read was about setting up profiles in web sites/web applications which I also found quite useful.
I have never really done any remote debugging of web applications so it is a useful tool to understand. Usually I prefer to run a test program on my machine which connects to the data but I appreciate there will be occasions where that isn’t possible.
I also had some problems today when.the visual studio wasn’t ran as administrator. Although I set up Visual studio to run as an administrator, it didn’t seem to do this if you open it by clicking on a project file.
I have found a couple of good articles about setting up remote debugging
I have also found a couple of interesting youtube videos on the subject
