Supressing Finalize code for this object may be an option to overcome the problemclass GoodMapServerDcomproxy : MapServerDcomProxy { public GoodMapServerDcomproxy(IServerContext context, bool releaseContextOnDispose, DcomProxy proxy) : base(context, releaseContextOnDispose, proxy) { if (proxy == null) { GC.SuppressFinalize(this); } } }Another workaroundChange the unhandled exception policy back to the default behavior that occurs in the .NET Framework 1.1 and in the .NET Framework 1.0. More information regarding this way of supressing error message can be found at http://msdn.microsoft.com/en-us/library/ms228965.aspx. By implementing this workaround, serious programming problems can go undetected, so proceed with caution.To enable this default behavior, add the following code to the Aspnet.config file that is located in the following folder: %WINDIR%\Microsoft.NET\Framework\v2.0.50727<configuration> <runtime> <legacyUnhandledExceptionPolicy enabled="true" /> </runtime></configuration>
