Welcome back! This is Mike Clay again with the Microsoft ASP.NET Developer Support team. I have authored Support Voice columns in the past. This month, I want to wrap up some of the previous debugging topics I covered and touch on a few issues that we still see pretty frequently in PSS. I wanted to discuss the basic configuration and permissions required for debugging in Visual Studio .NET and provide a few more helpful resources that can be difficult to find. We have lots of debugging information and documents available, which can be a bit overwhelming sometimes, especially if you are new to ASP.NET debugging. I thought it would be helpful to put the core debugging requirements in one place and let this be a starting point for common errors that developers frequently run into. The purpose here is not to go into too much detail, but simply to provide developers with a quick checklist before you try to debug ASP.NET applications.
Recap of debugging permissions in ASP.NETLet me first mention that for all scenarios discussed below, I am referring to automatic debugging. Automatic debugging is when you either push the blue Start button or press the F5 key in Visual Studio .NET. This automatically attaches to the aspnet_wp.exe or w3wp.exe worker process for you. Manual debugging is when you manually attach to the appropriate process through the Debug menu. With either method, there are some key concepts to keep in mind.

Local or remote debugging?This is very important in terms of the debugging configuration because local debugging has fewer requirements than remote debugging. Usually, local debugging in Visual Studio .NET works right out the box, assuming the developer is a local administrator.
PermissionsAs mentioned before, not much configuration is required for local debugging. However, remote debugging has the following main requirements:

TroubleshootingOnce you have the correct configuration and minimum permissions in place, there are still some common errors you can run into. We have touched on troubleshooting steps and resources in the following Support Voice column:

I hope you found this information helpful in easing some of the initial confusion involved with ASP.NET debugging. Remember, the Support Voice columns are for the YOU!
