I wonder if the patch in bug 597950 fixes this issue.

please confirm.

I have been able to make some progress on this. It's available in a branch of my git clone on gitorious :
http://gitorious.org/~bl8/banshee/bl8-clone/commits/monodevelop-debug

I'm currently able to debug Banshee using mono 2.4.2.3 and MonoDevelop 2.2.1, but it hangs during startup, when loading webkit.
I'd like to know if anyone has the same problem with other versions.

By the way, some changes in the patch from bug 597950 do help for debugging, but there are other changes in the .csproj files needed.

Bertrand, that's good news.

I wonder if the hang is a bug of the debugger, because with the last versions I've been getting lately an exception at startup when trying to load webkit, but the exception doesn't prevent me to run Banshee in the end. The stacktrace:

I guess it will go away if disabling the Wikipedia extension.

Andrés,

I think your problem happens because your webkit-sharp.dll.config points to the wrong webkit-1.0.so file. See this commit :
http://anonsvn.mono-project.com/viewvc?view=revision&revision=144155

So I don't think it's directly related to the debug problem.

Just tried your branch and debugging works! I could stop at breakpoints and step in/over.

By the way, when debugging Banshee doesn't pick up the BANSHEE_DEV_OPTIONS environment variable.

After chatting with Bertrand on IRC, it appears to be the limitation of MD which doesn't expand the $(VAR) macros. Hardcoding it in Nereid project options (Run -> General) works.

Relevant MD bug: https://bugzilla.novell.com/show_bug.cgi?id=404157

The sooner this gets into trunk the easier it'll be for people to
contribute.

Can someone please update this bug or create a blog entry for how exactly I'd setup MD to be able to debug Banshee.

Keep up the good work.

Allow debugging from MonoDevelop

This patch contains the changes from my monodevelop-debug gitorious branch, against the latest master.

The problem of not picking up the value of BANSHEE_DEV_OPTIONS is still there, but I think the gain of debugging outweighs this annoyance. So I'd be willing to commit this if people have no objections.

Looks good to me :)  Thanks, Bertrand!

This problem has been fixed in the development version. The fix will be available in the next major software release. Thank you for your bug report.
