WinForm crashing when accessing resources

Question

I am developing a WinForm application and I have some embedded resources (the graphic layout of the form). The problem is that when I start the application on my machine it runs perfectly, but if I pass it on another pc it may or may not work. On the last computer I tried (Windows 7 64bit, .NET 4.0 installed) it blocked when I tried to access resources. Here is the code which blocks the app, and below there is the full exception thrown.

//Note: notifierName is a string passed as an argument
_icon = new NotifyIcon
{
    Text = notifierName,
    Icon = SystemIcons.Application,//Properties.Resources.Tray,
    Visible = true
};
try
{
    _icon.Icon = Properties.Resources.Tray;
}
catch (Exception e)
{
    Logger.WriteLog(e.ToString());
}

After tracking down what was causing the exception, I tried to set all resources to "embedded resources", the .exe was doubled in size (so the images were actually saved in there) but the same error occurred. I think I'm missing something about how resources work, because passing the same exe on another machine isn't causing all these troubles. Thanks for your help.

This error occurs about when you compile an application with .Net 4.5 but run on 4.0.In .Net 4.5 ExtensionAttribute removed from System.Core and add mscorlib.

Could not load type 'System.Runtime.CompilerServices.ExtensionAttribute' from assembly 'mscorlib

Could not load type 'System.Runtime.CompilerServices.ExtensionAttribute' from assembly 'mscorlib, Version=4.0.0.0 Error

Great suggestion, surely you're right. Now, how can I change the target platform to .NET 4.0 from solution properties in VS? – Niccolò Campolungo Feb 22 '14 at 10:08
I think change target but you can test both. – Feb 22 '14 at 10:09
It is already set to .NET 4.0, but now I think the problem could be in a referenced DLL. I'm going to check it out – Niccolò Campolungo Feb 22 '14 at 10:11
It's yet crashing. The only dll I am referencing is protobuf-net (from Marc Gravell) and I am 100% sure I am passing the .NET 4.0 version. – Niccolò Campolungo Feb 22 '14 at 10:20
