Hi,

Even you are build under the release mode, the IDE still resident inside your memory. It handle lots of your controls that youe application not need.

If you really want to know how much your app take up the momory then build the release mode. Close the IDE, run your app. Then check again.

Ops... one more things .... try to unload the not use control and reference from your projects. It will slow down your app and take huge of memory.
