This is a possible regression issue as Custom NuGet feeds work just fine in XS 5.8.2 and 5.8.3. However in XS 5.9, custom nuget feeds seem to not work as intended. It seems that all operations on packages that come from the custom feed fail, see attached screenshot regarding more information.


1. Install XS 5.9(Currently on Alpha)
2. Xamarin Studio -> Preferences -> NuGet -> Sources -> Add(Custom NuGet Feed Information)
EX: Mobile Essentials / http://gallery.mobileessentials.org/feed.atom

Note: This is not 100% reproducible, but has happened to myself a couple times while playing around with various custom NuGet feeds using XS 5.9.

Please let me know if anything else is needed.

This is 100% reproducible for every member of my team against our TeamCity NuGet feed.
Comment 2 Matt Ward 2015-04-14 13:20:23 UTC
Please can you provide the IDE log?
Comment 3 Matt Ward 2015-04-14 13:36:32 UTC
I can repro with Team City. It looks to be a Mono 4.0 installer problem. The Mono 4.0 installer is not creating the directory:


The workaround is to create the above directory. The registry subdirectory is missing.

Exception callstack:

Comment 4 Michael Teper 2015-04-14 14:04:54 UTC
Matt, I created the following folder and it made no difference. Where do I find the log you were interested in?

Comment 5 Matt Ward 2015-04-14 14:09:41 UTC
You can get to the IDE log by opening the Help menu and selecting Open Log Directory. If possible can you reproduce the problem using the Add Packages dialog instead of the Package Sources. That should log a exception callstack.
Comment 6 Michael Teper 2015-04-14 14:28:39 UTC
The log contained a similar access error for


Once I created that folder, I no longer got an error.
Comment 7 Matt Ward 2015-04-15 07:42:17 UTC
I have patched NuGet to not check the registry on Mono. The changes are on a separate branch:


If the Mono installer is modified to create the registry/LocalMachine directory then the NuGet change would not be required to fix this bug.

Comment 9 Alexis Christoforides 2015-04-22 16:29:13 UTC
I haven't been able to reproduce the behavior, but the missing directories are now included in the following package for testing:

@Alexis - The Mono package fixes the problem, thanks.
