SYMPTOMS
When you use Microsoft .NET Framework remoting in Microsoft Visual Studio .NET, you may receive an &quot;Unhandled Execution&quot; error message. The error message text indicates that the handle is not valid.

The following is an example of a fusion log that may appear when this error occurs: at System.Runtime.Remoting.Channels.Http.HttpClientTransportSink.GetCurrentSidString at System.Runtime.Remoting.Channels.Http.HttpClientTransportSink.SetupWebRequest(IMessage msg, ITransportHeaders headers) at System.Runtime.Remoting.Channels.Http.HttpClientTransportSink.ProcessAndSend(IMessage msg, ITransportHeaders headers, Stream inputStream) at System.Runtime.Remoting.Channels.Http.HttpClientTransportSink.ProcessMessage(IMessage msg, ITransportHeaders requestHeaders, Stream requestStream, ITransportHeaders& responseHeaders, Stream& responseStream) at System.Runtime.Remoting.Channels.BinaryClientFormatterSink.SyncProcessMessage(IMessage msg)

Exception rethrown at [0]: at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) at Willis.Business.Placement.PlacingFileApplicationManager.W_NET_PlacingFile_AS.PlacingFileApplicationManager.SavePlacingFile(PlacingFile pPlacingFile, Boolean pKeepLock) at PlacingFileComplete.PF_Create.PlacingFileCreate at PlacingFileComplete.PF_Create.btnCreateUpdate_Click(Object sender, EventArgs e) at System.Web.UI.WebControls.Button.OnClick(EventArgs e) at System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) at System.Web.UI.Page.ProcessRequestMain
