Works for me:

var assembly = Assembly.Load("System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089");
var type     = assembly.GetType("System.Windows.Forms.Button");
var button   = Activator.CreateInstance(type);

To get full assembly name from .dll file:

var assemblyFileName = @"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.1\System.Windows.Forms.dll";
var assembly         = Assembly.LoadFile(assemblyFileName);
var assemblyName     = assembly.GetName().ToString();
