Wiki

Please, read the wiki to know everything about MemoScope. Lot of pictures, animated gifs and some text for every major features.

TLDR

What it MemoScope.Net ?

It's a tool to analyze .Net process memory: it can dump an application's memory in a file and read it later. The dump file contains all data (objects) and threads (state, stack, call stack)

MemoScope.Net will analyze the data and help you to find memory leaks and deadlocks

Thanks to Lee Culver for his ClrMd library, without it, MemoScope.Net would not exist.

Use cases

Out of Memory

I know, with 64 bits apps it should not be an issue but computers only have a few a few Go so it may still happen if your application :

• is using too much memory (peak)
• runs for days and has a "slow" memory leak

Dead lock

If your application is locked and you want to know where and why: dump the memory, display the threads status and blocking objects to see what thread is holding one that is waited by another thread.

Hard to reproduce bug

Sometimes, users can do weird things with your application and you can't make it happen on your computer so ask the user to dump its application's memory to analyze it on your machine.
