I have an ASP.NET application (.NET 4.0) on Windows 2008 Server (IIS 7.0). I've installed a Microsoft web express but it doesn't support attach to process feature; also I don't want to transfer source code to the server.
Is there any way to remotely attach w3wp.exe and debug .NET local code (I have RDP administrator access on server) ?
I don't think anything other than Visual Studio Professional has "Attach to Process" which works over a network.
If/when you do get hold of VS Professional, you should read about msvsmon - the remote debugging feature of Visual Studio. msvsmon is a little bit of software that sits on the server and enabled a remote debugging scenario.
