Our sincere thanks to everyone who has contributed on this bug
tracker over the years. Thanks also for your understanding as we
make these adjustments and improvements for the future.
Please create a new report on
Developer Community or GitHub with
your current version information, steps to reproduce, and relevant error
messages or log files if you are hitting an issue that looks similar to
this resolved bug and you do not yet see a matching new report.
See attached project. This hit the profiler.
If you run it with new ref count, click the button and then swap tabs it will die.
If you change it to be
x = new MyDel ();
v.Delegate = x;
it does not die.
