We are using the last version of v6 and are experimenting with using it in a .NET web service. It works fine but doesn't seem to release the image correctly. After rotating the image, we do a .releasegdpicture, then a cleargdpicture and then set the object to nothing. Is there anything else we're missing? Is there any way to 100% clear all things gdpicture out of memory? When we stop our web service then restart it we get an error saying it cannot copy the dll to the output directory because the files are in use by another process.
