If you’re like me, you probably saw this tool window after installing Visual Studio, closed it immediately, and never thought of it again. If you go to Debug | Windows | Show Diagnostic Tools, you’ll see this window. Detect a Memory Leak problem with the Diagnostic Tool Window Let’s move on to my best practice techniques list: 1. NET classes (like Marshal) or PInvoke (there’s an example of this further on). You can easily allocate unmanaged memory yourself with special. Usually, these classes implement a Dispose method, which frees the memory (we’ll talk about that later). Almost anything that involves streams, graphics, the file system or network calls does that under the hood. This is not so hard to do.NET itself has a lot of classes that allocate unmanaged memory. The second cause is when you somehow allocate unmanaged memory (without garbage collection) and don’t free it. This can happen, for example, when you register to events but never unregister. Since they are referenced, the garbage collector won’t collect them and they will remain forever, taking up memory. The first core cause is when you have objects that are still referenced but are effectually unused. There are 2 related core causes for this. How can my memory leak when there’s garbage collector ( GC) that takes care to collect everything?
In a garbage collected environment, the term memory leaks is a bit counter intuitive. Finally, I’ll include strategies to monitor and report on memory leaks for a deployed program. These techniques will teach you to detect when there’s a memory leak problem in the application, to find the specific memory leak and to fix it.
NET developers that advised me for this article. I’ll list 8 best practice techniques used by me and senior. You might not notice when there are few of them, but you always have to be on guard in case they overpopulate, break into the kitchen, and poop on everything.įinding, Fixing and learning to Avoid Memory Leaks is an important skill.
