Launching Xamarin iOS app fails with log message "An error occurred searching types for the given assembly"

Summary

I'm trying to develop an iOS app in Visual Studio based on Xamarin Forms, but what I'm finding is that the app fails to launch on my phone when I try to run it. I have a valid iOS development certificate and I've been able to launch the app in the past, although I'm not sure what could have changed between then and now (I've been working on it very on and off).

The error I'm getting within Visual Studio's debug console is Launch failed. The app '<<app name>>' could not be launched on '<<my iPhone>>'. Please check the logs for more details.

I've included the Xamarin logs further down.

Environment

I'm developing my project in Visual Studio on a Windows 10 PC. I'm using a MacBook Pro on the same network as the Xamarin Mac agent, and that's connected by USB to an iPhone 6s Plus which serves as the build target.

Installed Nuget packages

<packages>
  <package id="Microsoft.Bcl" version="1.1.10" targetFramework="portable45-net45+win8+wpa81" />
  <package id="Microsoft.Bcl.Build" version="1.0.21" targetFramework="portable45-net45+win8+wpa81" />
  <package id="Microsoft.Net.Http" version="2.2.29" targetFramework="portable45-net45+win8+wpa81" />
  <package id="modernhttpclient" version="2.4.2" targetFramework="portable45-net45+win8+wpa81" />
  <package id="rda.SocketsForPCL" version="1.2.2" targetFramework="portable45-net45+win8+wpa81" />
  <package id="WebSocket.Portable.Core" version="1.2.6" targetFramework="portable45-net45+win8+wpa81" />
  <package id="WebSocketSharp" version="1.0.3-rc10" targetFramework="portable45-net45+win8+wpa81" />
  <package id="Xamarin.Forms" version="2.3.1.114" targetFramework="portable45-net45+win8+wpa81" />
</packages>

Further Details

When I try to execute my app, I get the following error logs. The root cause seems to be that it cannot find the C# type System.ComponentModel.Win32Exception:

Update

After upgrading to Xamarin 4.1.2.18 based on Marcos' response I find that I still can't debug my app but I get a different error log output, posted here (because I can't fit it within this post body).

It does still complain about not finding Win32Exception, however.

Update 2

I can build and launch Xamarin iOS apps that are developed on my Macbook Pro within Xamarin Studio

I can successfully launch and debug my (actual) Xamarin Forms app using an iOS simulator from my Windows machine (this is actually really useful if I can't resolve this bug).

I cannot successfully launch/debug my actual Xamarin Forms app on my actual iPhone from my Windows machine.

xvs/idb/4.1.1.3/launch-app if you watch in the error I saw a version lower to the update in your VS2015, both xamarin need to be in the same version in the mac and the windows.

Make sure when you conect with the Xamarin Mac Agent have the same version that you have in your windows
