title: .NET 4.0 assembly built on windows 8.1 does not work on lower windows versions
body: <p>We have a project consisting of c++ core library and .NET wrappers (2.0 and 4.0) using Marshall. Build machine has Windows 8.1 OS.</p>
  
  <p>C++ core and .NET 2.0 wrapper are built using MSVC 2005 and works perfect on other machines with lower windows versions.</p>
  
  <p>.NET 4.0 wrapper is built using Microsoft SDK 7.1. Library works fine on build machine, but crashes on other machines (with .NET 4.0 installed) with following error:</p>
  
  <pre><code>Exception: System.MissingMethodException: Method not found: 'IntPtr System.Runtime.InteropServices.Marshal.GetFunctionPointerForDelegate(!!0)'.
  </code></pre>
  
  <p>It seems like wrapper was built using higher version of .NET and i have no idea how to solve this. As far as i understood there is no way to force using specific version of .NET 4.x while building though they are not backwards compatible.</p>
