52924 ms GetAdditionalResourcesFromAssemblies 1 calls
Build succeeded.

Probably duplicate:
Comment 3 Jeremy Kolb 2016-11-18 15:23:14 UTC
@Patryk that looks like the same bug.
Comment 4 dean.ellis 2016-11-23 10:52:42 UTC
Fixed in xamarin-android/master/2f690ca7

This has also been cherry-picked to the cycle9 branch.

How do I tell which build has this bug fix in it?  I looked at the release notes for the current beta and alpha but did not see 47288 anywhere.  I'm assuming that this bug number corresponds to the release notes that say something like:

Fixed: 45134 - "Go to folder" shortcut in file dialogs doesn't accept Cmd+v.

I looked for "Fixed: 47288" but could not find it in beta or alpha.
Comment 7 Joey Z 2017-02-09 01:14:57 UTC
I found it in beta channel by manually testing.  My build times have shrunk by about 4 minutes.  Thanks for fixing this bug!
