I’ve tried to debug sample ASP.NET and ASP.NET MVC applications in MonoDevelop 2.4 (on Mono 2.8 on Windows 7) but breakpoints doesn’t work.
If debugging MVC Application MonoDevelop prints the following into the output:
Mono.Debugger.Soft.VMDisconnectedException: An exception of type "Mono.Debugger.Soft.VMDisconnectedException" thrown.
at Mono.Debugger.Soft.Connection.SendReceive(CommandSet command_set, Int32 command, PacketWriter packet)
at Mono.Debugger.Soft.Connection.Type_GetInfo(Int64 id)
at Mono.Debugger.Soft.TypeMirror.GetInfo()
at Mono.Debugger.Soft.TypeMirror.get_FullName()
at Mono.Debugging.Soft.SoftDebuggerSession.HandleEvent(Event e, Boolean dequeuing)
at Mono.Debugging.Soft.SoftDebuggerSession.HandleEvent(Event e)
at Mono.Debugging.Soft.SoftDebuggerSession.EventHandler()
If debuffing ASP.NET application MonoDevelop silently finishes debugging after a second or two and sometimes leaves a hanging black console window (mono.exe).
Does anybody know is debugging of Web Applications supported by MonoDevelop? Or maybe how to make it work?
Upd:
Also there are error messages in MonoDevelop log after each attempt to debug. In Mono 2.8 no errors appear but for older versions (2.6.7, 2.6.4) they are.

After looking throuth MonoDevelop.Debugger.Soft.AspNet sources i figured out that it supossed to work only with versions 1.0 & 2.0 of runtime. I’ve changed the runtime version of my test project but no changes…

ASP.NET debugging is supported with the soft debugger, but Windows support for the soft debugger has not been tested very much. In your specific case it looks like the targeted Mono runtime is crashing when in debugging mode. Could you file a bug report?
Also, the upcoming MonoDevelop 2.4.1 adds support for debugging the 4.0 framework.
UPDATE: it looks like there is a bug filed already.
