Description Sergei 2017-12-05 08:45:19 UTC
I've just updated to 15.5.
After starting Visual Studio (without project loading) such message appears: "MonoAndroidDesignerPackage was not loaded correctly". In ActivityLog.xml there is exception:

And Android Designer just doesn't work. Have you ever tested your new version 15.5?
Comment 1 Sergei 2017-12-05 08:49:56 UTC
I can't open ios storyboard too. Error message appears: "the type initializer for Xamarin.Designer.BaseStyles threw an exception".
Comment 2 Ian Griffiths 2017-12-05 12:21:03 UTC
I notice that the error message includes an entry in the Xamarin.AndroidDesigner.Resources.ScreenOrientationQualifier type initializer. In case it's of any relevance, my system (which has hit exactly this same error after upgrading to 15.5) is a multi-monitor setup, with a mixture of screen DPIs. (One central 4k 17" laptop display configured for 150% scale, flanked by a couple of 'normal' 100dpi external monitors configured for 100% scale.)
Comment 3 Sergei 2017-12-05 12:24:12 UTC
Additionally, it seems that restoring of Visual Studio installation fixes this problem. And this problem reproduces only on several computers, so it can depend on system configuration.
Comment 4 Mikael Nensén 2017-12-08 13:13:53 UTC
I have the exact same issue, just installed the latest version and I can't open my storyboard files.

*** Bug 61048 has been marked as a duplicate of this bug. ***
Comment 7 Alan McGovern 2017-12-08 15:34:39 UTC
We're looking into this and will give you an update as soon as we know more. Thanks!
Comment 8 Mikael Nensén 2017-12-12 10:21:13 UTC
Any update on this? My VS2015 Xamarin installation at work is unusable. I'm currently working from home on a VS2017 installation that my stationary computer is running. But I need to also be at the office. So, what's going on? When and where can I download a version that will fix my VS2015 installation/setup?
Comment 9 Daniel Cazzulino 2017-12-12 12:34:27 UTC
For those seeing this in VS2015, first run after installation may not work. Restarting VS solves that particular "first run after install" issue.

Could you try that please?
Comment 10 Mikael Nensén 2017-12-12 21:33:38 UTC
This is the original issue that I'm having, as you can see and from my post above, there are multiple assemblies missing. I've restarted my computer and done the installation 3 times. Opened the solution multiple times. Nothing helps. The assemblies listed are not located on my computer since after installing 15.5.

https://bugzilla.xamarin.com/show_bug.cgi?id=61048

Is there a link somewhere to the previous version? 15.4? So that i might download it and hopefully things will start working again.
Comment 11 Mikael Nensén 2017-12-12 21:37:37 UTC
There are 12 assemblies missing that can't be loaded by MEF (search for Error). They are listed above and in my original issue's attachment (ActivityLog.xml).

Just do a 15.5.1 release and include the missing assemblies?
Comment 12 Alan McGovern 2017-12-13 00:53:02 UTC
Can you confirm that the files really do not exist in your visual studio 2015 installation directory? There's a known issue with MEF in VS2015 where it can display this error even though the files exist.

C:\PROGRAM FILES (X86)\MICROSOFT VISUAL STUDIO 14.0\COMMON7\IDE\EXTENSIONS\XAMARIN\XAMARIN\Xamarin.VisualStudio.IOS.Properties.dll

If you could give us a full file listing for the path in C:\PROGRAM FILES (X86)\MICROSOFT VISUAL STUDIO 14.0\COMMON7\IDE\EXTENSIONS\XAMARIN that would be very useful. Thanks!
Comment 13 Mikael Nensén 2017-12-13 08:18:37 UTC
I have 0 files in that folder.

I have 25 folders...
