Warnings after update Xamarin Studio

Question

I just updated Xamarin Studio to the latest version (Xamarin.Android Version: 4.6.4 (Business Edition)) and I'm receiving a lot of warnings after the update..:

/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets: Warning: Reference 'mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=xxxxx' not resolved (TrackandTrace.Droid)

/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets: Warning: Reference 'Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=xxxx' not resolved (TrackandTrace.Droid)

I already tried to remove the reference and re-add it without any effect.

Update: Even if i create a new project I receive 2 errors right from the start.. These errors make unable to build android projects.

What exactly is the question? Are you worried that your code won't compile or are you just worried about the warnings? — Bryan, Apr 15 '13 at 14:09
@Bryan I'm just worried about the warnings. Where do they come from? how do I fix them. — Florian Schaal, Apr 15 '13 at 15:04

I also experienced that after upgrading(I believe you tried in release mode) try to change your appropriate architectures in your applications properties (if not sure, select all 3)

Try following (only a guess):

Find following Path: C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETPortable\v4.0\Profile\Profile104\SupportedFrameworks

In that directory add a new xml file with that name: "MonoAndroid, Version=v1.6+.xml". And the following Content:

<?xml version="1.0" encoding="utf-8"?>
<Framework DisplayName="Mono for Android"
  Identifier="MonoAndroid"
  Profile="*"
  MinimumVersion="1.6"
  MaximumVersion="*" />

Restart Visual Studio and try it again.

As you can read in the title im using Xamarin Studio and im using a Mac.. Do you know the link for mac?. — Florian Schaal, Apr 26 '13 at 09:58

I had a similar problem when I tried updating a couple of weeks ago. Some useful advice I got from the support/bug fixing team:

Inside Xamarin Studio, click Help-->Check for Updates. Change the update channel from Stable to Alpha (or Beta) and try that version. If that doesn't work, you can roll back to a previous version by going to:

http://store.xamarin.com/account/Products and clicking on Show Recent Releases on the bottom right.

Add Microsoft.AspNetCore.SignalR.Client.Core NuGet package to your core project and that should fix the issue.

See "Can not resolve reference: `System.Memory`" or "Could not find `System.Memory`" after update to Visual Studio 2017 version 15.8 Preview for details.
