1) The provided C# example fails to compile due to a conversion error. Example fixes:
A) Replace cwt.TryGetValue(wr2.Target, out data) with cwt.TryGetValue((ManagedClass)wr2.Target, out data)
B) Replace var cwt = new ConditionalWeakTable<ManagedClass, ClassData>(); with var cwt = new ConditionalWeakTable<object, ClassData>();
2) Possibly it's worth adding a note that the example may fail to function in debug mode, since in-scope variables are ineligible for collection during debug.
Type of issue
Code doesn't work
