I was afraid of that.
Thanks for your explanation.
In version 9.3, our console application works on server and desktop.
I can't use the method "ComReleaser.ReleaseCOMObject(parameterObjects)" from "ESRI.ArcGis.ADF.Connection.Local on my server.
Do you think that it is enough if i release my cursor with the .NET method ?
System.Runtime.InteropServices.Marshal.ReleaseComObject(parameterObjects);
Thank you for your help
