Description Matt Ward 2014-11-05 05:32:53 UTC
To reproduce:

Tested this on Windows but the behaviour should be the same on Mac.

1) In Xamarin Studio create a new solution - Blank App (Xamarin.Forms Portable).
2) Make sure your project's target framework is above 3.2. By default it will be the latest Android project target framework which should be version 4 or above anyway.
3) Right click the solution and select Update Packages.
4) Compile the solution.

Expected result:

Compilation works.

Actual result:

The compilation fails with the error:

C:\Program Files (x86)\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2,2): Error: Exception while loading assemblies: System.IO.FileNotFoundException: Could not load assembly 'Xamarin.Android.Support.v13, Version=, Culture=neutral, PublicKeyToken='. Perhaps it doesn't exist in the Mono for Android profile?
File name: 'Xamarin.Android.Support.v13.dll'
   at Xamarin.Android.Tuner.DirectoryAssemblyResolver.Resolve(AssemblyNameReference reference, ReaderParameters parameters)
   at Xamarin.Android.Tasks.ResolveAssemblies.AddAssemblyReferences(ICollection`1 assemblies, AssemblyDefinition assembly, Boolean topLevel)
   at Xamarin.Android.Tasks.ResolveAssemblies.Execute() (wwefwfwe.Android)


Looking at the Android project the Xamarin.Android.Support.v13 has not been installed when the v4 package was updated. The new Xamarin.Android.Support.v4 NuGet package has the v13 package as a dependency for Android projects with a target framework of 3.2 or above.

Trying the same thing in Visual Studio (by running Update-Package in the package manager console) and Visual Studio correctly installs the v13 package on updating. Compiling the solution after the update also works.

I have checked this issue and with the help of steps mentioned in bug description I am able to reproduce this issue.

When I update the package of solution, packages updated successfully but when I try to build the project XS shows following error:

"Error: Exception while loading assemblies: System.IO.FileNotFoundException: Could not load assembly 'Xamarin.Android.Support.v13, Version=, Culture=neutral, PublicKeyToken='. Perhaps it doesn't exist in the Mono for Android profile?"

I have also observed that when I try to update the package by "Right click on Package directory under android project" I am not getting any error and application is working fine.

Note: I am getting same behavior on Mac and windows but the same is working fine on windows for VS.

I have checked this issue with builds below

Mac OS X 10.9.4
Xamarin Studio : 5.7 (build 596)
Mono 3.12.0 ((detached/b75fa2b)
GTK+ 2.24.23 (Raleigh theme)
Xcode 6.1 (6602)
Xamarin.iOS : (Enterprise Edition)

Now this error does not occur and I am getting different error. So I have filled a different bug for this i.e bug https://bugzilla.xamarin.com/show_bug.cgi?id=24840 

And I am closing this issue.
