+Summary: VM can't locate MONO DLLS.
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+Simple mono applications requiring libraries compile but don't run. A small
+instrument simulation requires the following packages
+
+using System;
+
+using System.Drawing;
+
+using System.Collections;
+
+using System.ComponentModel;
+
+using System.Windows.Forms;
+
+using System.Data;
+
+using System.Net;
+
+using System.Net.Sockets;
+
+using System.Threading;
+
+I am unsure if this is a pure .Net application. It may not be. The FAQ
+states that System.Windows.Forms is not yet ready. It is unclear what
+release the FAQ applies to. I don't know how to evaluate the above code
+against the release notes scope statements.
+
+It compiles in MonoDevelop without errors indicating that the imported
+packages are available to the compiler. When I try to run the program, the
+following happens.
+
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object

+My friend locate tells me that I have several copies of the libraries
+available. For example 
+
+[hamby@dhamby hamby]$ locate System.Drawing.dll
+/usr/lib/mono/1.0/System.Drawing.dll
+/usr/lib/mono/gac/System.Drawing/2.0.3600.0__b03f5f7f11d50a3a/System.Drawing.dll
+/usr/lib/mono/gac/System.Drawing/1.0.5000.0__b03f5f7f11d50a3a/System.Drawing.dll
+/usr/lib/mono/2.0/System.Drawing.dll
+
+I last installed Mono from the Release 1.0 mono-all.zip for Fedora Core 2.
+
+Steps to reproduce the problem:
+1. Install Mono 1.0 for Fedora Core 2 on Fedora Core 2
+2. Compile sample program
+3. Run sample program
+
+Resuidual beta versions of Mono are present.
+
+Actual Results:
+
+Program throws unhandled exceptions 
+
+Expected Results:
+
+Program runs. Wonderful things happen. Client connects and receives sample
+data. Just like on Windows.
+
+This system will build the MonoDevelop c# Console hello application. It
+even does all the typing for me. 
+
+Is this an installation glitch or am I ahead of the curve with this little
+example written by others for Visual Studio .Net?
+How often does this happen? 
+
+
+Additional Information:
+
+I'll try this program with Mono on Windows some day. It is well behaved
+using SharpDevelop, the give-away Microsoft C# compiler and redistributable
+runtime. I took one look at the Visual Studio 2005 Beta license, clicked
+"cancel", then "move to trash".
+
+Could you recommend how to clean up the older versions? I'd like to pull
+off all of mono and reinstall the Release 1 kit.
+
+Thanks for a valiant effort and your usual thoughtful support.
