Debug asp.net without Visual Studio

Is there any way I can debug asp.net application without Visual Studio. I mean I have all aspx and .cs files in the folder but the system doesn't have Vis开发者_JAVA技巧ual Studion installed in it. Is there any way I can debug it via breakpoints?

It's not going to be easy but .net does have a command like debugger:

You would need to attach it to IIS or whichever process is hosting your site and I don't think it's easy to add the breakpoints, but it would do the trick.

However, the simpler option would probably be to get Visual Studio Express edition, it's free and does let you debug stuff.

I've no idea if it's possible to create breakpoints and such without visual studio, but you could perform basic debugging by adding code to the existing files that outputs whatever you need (variable values, caught exception messages?) to a log file?
