title: Monodevelop. Method that visible from Assembly Browser not found. (CS0584)
body: <p>I have the .dll that is part of AForge.NET framework. I can't compile project because:</p>
  
  <pre><code>Error CS0584: Internal compiler error: Could not import type `AForge.Imaging.Filters.Sepia' from `AForge.Imaging, Version=2.2.4.0, Culture=neutral, PublicKeyToken=ba8ddea9676ca48b' (CS0584) (projectName)
  Error CS0584: Internal compiler error: Could not import type `AForge.Imaging.Filters.Invert' from `AForge.Imaging, Version=2.2.4.0, Culture=neutral, PublicKeyToken=ba8ddea9676ca48b' (CS0584) (projectName)
  Error CS0584: Internal compiler error: Method not found: 'AForge.Imaging.UnmanagedImage.CollectActivePixels'. (CS0584) (tryingImageProcessing)
  </code></pre>
  
  <p>But all of these methods and classes are visible from the assembly browser.

  <p><em>Hope this post wouldn't be treated as copy of my previous: question of that post is completely different from current.</em> </p>
  
  <p><strong>UPDATE:</strong> 
  Well, I've found what the problem was. @Jason was right: I haven't compiled libraries against MonoTouch, it was compiled against Mono. So I've created new projects and past sources there. AForge (Core) and AForge.Math compiled perfectly while AForge.Imaging hasn't: System.Drawing from github.com/mono/ implement some functions that AForge.Imaging needs. Hence, there is no solution by now. </p>
