+Summary: Assembly.CreateInstance donn't work as in MS.NET
+
+Description of Problem:
+Assembly.CreateInstance(string className) throws a
+'System.TypeLoadException' if the class isn't found.
+On .NET 1.0 (can't test it with 1.1) it returns simply null
+
+Steps to reproduce the problem:
+1. compile the code bellow
+2. running the exe
+
+Actual Results:
+<output>
+I'm the constructor!
+ConsoleApplication.MyTest
+
+Unhandled Exception: System.TypeLoadException: A type load exception has
+occured.
+in (unmanaged)
+/usr/local/mono_05.05.2003/lib/libmono.so.0(mono_raise_exception+0x20)
+[0x40087325]
+in (unmanaged) /usr/local/mono_05.05.2003/lib/libmono.so.0 [0x4008d55e]
+in <0x00052> 00 System.Reflection.Assembly:GetType (string,bool,bool)
+in <0x00025> 00 System.Reflection.Assembly:CreateInstance (string,bool)
+in <0x00019> 00 System.Reflection.Assembly:CreateInstance (string)
+in <0x0007e> 00 ConsoleApplication.Class1:Main (string[])
+</output>
+
+Expected Results:
+I'm the constructor!
+ConsoleApplication.MyTest
+Null
+
+Additional Information:
+<code>
+using System;
+using System.Reflection;
+
+namespace ConsoleApplication
+{
+	class Class1
+	{
+		[STAThread]
+		static void Main(string[] args)
+		{
+
+      //this works as expected since the cllass exists
+      object newInstance =
+Assembly.GetCallingAssembly().CreateInstance("ConsoleApplication.MyTest");
+      if ( newInstance == null) {
+        Console.WriteLine("Null");
+      } 
+      else {
+        Console.WriteLine(newInstance.GetType());
+      }
+
+      //this throws a 'System.TypeLoadException'. but under .NET 1.0
+newInstance2 is null.
+      object newInstance2 =
+Assembly.GetCallingAssembly().CreateInstance("ConsoleApplication.Foo");
+      if ( newInstance2 == null) {
+        Console.WriteLine("Null");
+      }
+      else {
+        Console.WriteLine(newInstance2.GetType());
+      }
+
+		}
+	}
+
+  public class MyTest
+  {
+
+    public MyTest()
+    {
+      Console.WriteLine("I'm the constructor!");
+    }
+  }
+
+}
