Broken with Xamarin 5.3 build 423

[etcimon]

Since I updated to the latest Xamarin Studio alpha, the projects don't open anymore and when downgrading to older versions of Mono-D, the parser doesn't work at all...

[aBothe]

First off, try reinstalling Mono-D. Are D settings available in the global settings dialog? Just to make sure it loaded mono-d properly. I updated XS today as well and everything went fine.

[etcimon]

Yes, I tried restoring previous versions (in LocalInstall/Addins) compiled previous and master versions from git commits in Visual Studio 2013 as well, no luck. I re-downloaded and re-installed Xamarin as well from http://monodevelop.com/download following the Alpha updates again. I'll try a complete reinstall (without local folders) now. I just can't find last week's Xamarin installer, that would surely solve it for me

[etcimon]

I tried a complete re-installation, same issue. I could use a previous version Xamarin installer right now =)

[etcimon]

To be more specific, when I open a mono-d project all the menus go gray and the controls are disabled.

[aBothe]

Are there D options in the global options?

[etcimon]

Yep

[aBothe]

So it's actually loaded which is generally both a nice and a bad sign. :D
I'll reboot - time for heading on irc?

I have this in my logs:

Alright, I'm getting the update now as well. Let's see.

[etcimon]

Oh I hope you saved the earlier version :/

[etcimon]

I disabled the TaskListPad, that's apparently not the issue even though that particular error goes away from the logs

[aBothe]

okay, found out the issue.. Hopefully the reparse cycle isn't broken, as I experienced recently.

[etcimon]

Where do you put your breakpoints? I can't seem to find a good way to debug this, I'm not sure what the entry point is

[aBothe]

Okay, it is broken. Let's see whether I can workaround this.

[aBothe]

I just opened a project, waited a bit, broke execution.

[etcimon]

I get an issue about not finding the monodoc.xml

[etcimon]

Once I have the sources/ folder and monodoc.xml file in the same folder as the mono-d dll, the exceptions left are about mscorlib.XmlSerializers and Xwt.Gtk.Windows dependencies, and a NullReferenceException in the LazyProjectLoader.AddOrUpdateFiles call. Are the dependencies something you can just ignore?

[aBothe]

It primarily was this line

[etcimon]

Oh, I broke a junction when trying to reinstall. It's good now, thanks for fixing quickly =)
