+Summary: AppDomain does not honor AppendPrivatePath search path.
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+A plug-in framework I'm writing uses AppDomain.AppendPrivatePath to specify
+additional directories the AppDomain is supposed to use to resolve
+assemblies that correspond with the directories in the framework's search
+path.  Loading the dll file into a byte array, then subsequently calling
+Load on the byte array from an AppDomain fails because it cannot resolve
+the assembly.
+
+Out of curiosity,  why is the AppDomain attempting to resolve the assembly
+even though the entire assembly is in the byte array?
+
+Steps to reproduce the problem:
+1. Compile an AppDomain loading app that uses runtime search path additions
+using AppendPrivatePath.
+2. Try to load an assembly within the runtime added directory.
+3. 
+
+Actual Results:
+
+FileNotFoundException
+
+Expected Results:
+
+Everything works okay.
+
+How often does this happen? 
+
+Every time.
+
+Additional Information:
+
+Here is the relevant code from the library:
+
+		// Loads the content of a file to a byte array. 
+		protected byte[] LoadRawFile (string _filename) {
+			FileStream _fs = new FileStream (_filename, FileMode.Open);
+			byte[] _buffer = new byte [(int) _fs.Length];
+			_fs.Read (_buffer, 0, _buffer.Length);
+			_fs.Close ();
+   
+			return _buffer;
+		}
+		  
+		protected string SearchForModule (string _name) {
+			foreach (string s in _search_path) {
+				if (Directory.Exists (s)) {
+					foreach (string f in Directory.GetFiles (s, "*.dll")) {
+						string _f = f.Replace (s, "").Replace ("/", "");
+						Console.WriteLine ("Checking {0} against {1} ({2}) (Result: {3})",
+_name, _f, 
+							_f.Substring (0, _f.Length - 4), (_f.Substring (0, _f.Length - 4) ==
+_name));
+						if (_f.Substring (0, _f.Length - 4) == _name) {
+							return s + "/" + _f;
+						}
+					}
+				}
+			}
+			
+			return null;
+		}
+
+( in the LoadModule method )
+
+			AppDomain _tempDomain = AppDomain.CreateDomain ("_temp_" + _name);
+			
+			byte[] _raw_bytes = LoadRawFile (_filename);	
+			
+			// set up the search path
+			foreach (string s in _search_path) {
+				_tempDomain.AppendPrivatePath (s);
+			}
+			
+			// The throw here is mostly used from dep resolver calls, although it
+should also be caught by the immediate caller
+			// (i.e. the application).
+			try {
+				_tempDomain.Load (_raw_bytes);
+			} catch (BadImageFormatException e) {
+				throw new ModuleImageException (e.Message);
+			}
