Dec 01, 2012 · What’s not as convenient is the size required to store the raw dll as a byte array in the script. To alleviate the size dilemma, I’ve written a PowerShell script that reads in a managed dll, compresses it, base64-encodes it, and outputs generated code that you can simply paste into any script that requires the dll. The leak (object kept in memory) is caused by strong handles on the form, not by the missing Dispose(). Even if you use "using" or force a Dispose(), if the object is referenced it will not be removed from memory.

In the .NET SharePoint world, disposing site and web objects is routine and expected to avoid memory leaks. In PowerShell, I've noticed some unexpected behavior, for instance: Add-PSSnapin Microsoft.SharePoint.PowerShell $site = Get-SPSite <yourUrlToSiteCollection> $web = $site.OpenWeb() $web.Dispose() $site.Dispose() $list = $web.Lists["Announcements"] $item = $list.Items.Add() $item["Title"] = "New Announcement!" Nov 26, 2015 · No need for robocopy or regular expressions to do what PowerShell can already do on its own, this will speed up your script a LOT and remove the memory problems you were running into.

Dec 26, 2017 · But for memory hoard detection, it is useful to eliminate the "non-determinism" of the GC. Also, if you call RunspacePool.Dispose () it internally calls Close () so there is no need to call Close () before Dispose () AFAICT.

However, my experience is that the majority of PowerShell users are not comfortable with or interested in using PowerShell classes. (I make it a habit to ask if people are using classes, why/why not, and what for). I suspect the comfort level with a Dispose {} would be higher, but that is just my guess. I agree, though, it probably does need both. The reason it's not much of an issue is because the objects just hold up memory when the PowerShell app is running. Once you close out of PowerShell, the memory those sites/webs were using is now freed up. If I recall correctly, you'll only use a few MB of ram if you don't dispose properly, and that gets cleared once you close out of PowerShell...

Since those leaks happened over a fairly long period of the time, it was a bit difficult to troubleshoot by simply running the script in PowerShell ISE. The.Net framework which PowerShell runs on does automatic memory management; when variables go out of scope (e.g. after a loop, after a function returns) and the script no longer has access to some allocated memory, then the.Net garbage collector kicks in and cleans it up.
