On build host side:

[10-déc.-2013 08:52:30] Starting /Developer/MonoTouch/usr/bin/mtouch -v -sdkroot "/Applications/Xcode.app/Contents/Developer" --cache "/Users/iben/Library/Caches/Xamarin/mtbs/builds/HelloWorld1/79bff343-ce97-4f92-af6f-351f4cd8b877/output/temp/mtouch-cache" --nomanifest --nosign -dev "/Users/iben/Library/Caches/Xamarin/mtbs/builds/HelloWorld1/79bff343-ce97-4f92-af6f-351f4cd8b877/output/Debug/iPhone/HelloWorld1.app" -r "/Users/iben/Library/Caches/Xamarin/mtbs/builds/HelloWorld1/79bff343-ce97-4f92-af6f-351f4cd8b877/assemblies/Newtonsoft.Json.dll" -debug -linksdkonly -sdk "7.0" -targetver "6.1" --abi=armv7 "/Users/iben/Library/Caches/Xamarin/mtbs/builds/HelloWorld1/79bff343-ce97-4f92-af6f-351f4cd8b877/assemblies/HelloWorld1.exe"
[10-déc.-2013 08:52:31] Command [Build: CommmandUrl=Build] finished (46)

Os vs side:

3>System.InvalidOperationException: The operation cannot be completed because a build is already in progress.

To reproduce:

- create a hello world app in vs2012
- add nuget package Newtonsoft.json
- add this code in constructor: 
using Newtonsoft.Json;
var o = new JsonSerializer();

Build, rebuild, rebuild, rebuild util it fails.
You'll also remark that the build details are not available in VS or in mtbserver.log
The only way to see the error message is to copy and run the mtouch command line into a terminal
You should see error MT2002: Failed to resolve assembly: 'System.Dynamic.Runtime, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

note: duplicate of https://bugzilla.xamarin.com/show_bug.cgi?id=16066

You should still take the "only way to see the error message" part of my message, as this information is very important to understand what is happening.
Comment 2 softlion 2013-12-10 17:05:51 UTC
Additional info: to fix the problem with System.Dynamic.Runtime, replace the newtonsoft.json reference in the project file so it uses net40 instead of  net45. This is a "bug" in their nuget package configuration which does not know how to target xamarin.* projects.
