While these tools are not free, JetBrains does offer its memory unit testing tool for free. It’s called dotMemory Unit.

In this section, we will create a dotMemory Unit test to check whether we are leaking one of our objects. You can run these dotMemory Unit tests for free with .NET on the command line by downloading the standalone test runner here: https://www.jetbrains.com/dotmemory/unit/.
