I have discovered that with Visual Studio 2022 there no longer appears to be a code analysis mechanism in which objects that inherit from IDisposable but which are not then properly handled by a Dispose() call are detected, as used to be the case with the (apparently no longer available?) CA2000 compiler warning.
Have I missed some way to re-enable this mechanism, despite a whole bunch of googling? Or is there an alternative that can be used?
There’s a post on the Developer Community from 2024 in which Microsoft’s response is “It is hard to implement”. But the previously-available implementation was immensely valuable, even with an occasional false positive!
I’ve even tried installing the SonarQube for Visual Studio extension, but didn’t read its documentation closely enough before finding out it isn’t nearly as comprehensive as CA2000 was (and before finding someone else who complained to them about the gap).
