every single time.

Renders the IDE totally useless. It say's it's sending you crash reports.

can I work around this?

I handled the crash - that shouldn't happen anymore.

But it's caused by MonoDevelop.PackageManagement.Extensions the InstallPackageDataSource class crashes when trying to call ItemCount on the result it gives.

Are you using an addin of some sort ? If so try to disable that - this should be a partial workaround for the problem.
Comment 3 Matt Ward 2015-05-08 12:48:47 UTC
This looks to be the NuGet extensions addin causing the problem when you type into the search box. The 0.6 version of the NuGet extensions addin is not compatible with Xamarin Studio 5.9. To fix this you can uninstall the NuGet extensions addin or download a newer version from GitHub:


Download the .mpack from here. Then use the Add-in Manager and select Install from file to install the version 0.6.1 addin which works with Xamarin Studio 5.9.

Shouldn't this be backported to 5.9?

Mike, can you make a PR against cycle6?
Comment 7 Matt Ward 2015-11-16 10:12:22 UTC
This still seems to be a problem in Xamarin Studio 5.10 on the alpha channel. The fix was applied in commit:


If you have Xamarin Studio 5.10 installed and install the NuGet extensions addin 0.10 from:


Then trying to run a search with no solution open causes Xamarin Studio to crash:

I had the same issue, disabling the nuget extensions addin fixed the search again.

I have checked this issue with latest master XamarinStudio- and observed that now this issue works fine as shown in screencast: http://www.screencast.com/t/khLyDYWVr

Hence closing this issue.
