Description greg.rivington 2015-11-09 08:14:22 UTC
Updated to the latest alpha of Xamarin Android as we require the fix for https://bugzilla.xamarin.com/show_bug.cgi?id=32886

But now, we are getting 'Destination array was not long enough. Check destIndex and length, and the array's lower bounds'.

I have emailed Greg asking for a sample project  and version information.

Xamarin Studio in Windows
"Help -> About -> Show Details -> Copy Information [button]"

Visual Studio
"Help -> About Microsoft Visual Studio -> Copy Info [button]"

Xamarin Studio in OS X
"Xamarin Studio -> About Xamarin Studio -> Show Details -> Copy Information [button]"

Visual Studio 2012 reproduction solution

Hi Alan,

I’ve attached a Visual Studio 2012 solution that contains a WCF service project and an Android client project.

If you install the service on a machine and then change the variable name ‘machineNameRunningAndroidService’ to the name of the machine, you should see the issue.

I have left in our new workaround just so you are aware.

The issue was seen on the latest Alpha release that was available through: Visual Studio -> Tools -> Options -> Xamarin -> Android Settings -> Notify me about ‘Alpha’ updates.

But I currently have the latest Stable release as our workaround also means we do not see the following issue anymore (which is the reason our company hasn’t upgraded Xamarin for a while): https://bugzilla.xamarin.com/show_bug.cgi?id=32886 

Hope this helps!

This has been in NEEDINFO state for the past year, I suppose the problem does not exist anymore?
