Trimming unused code works great in NET Core.
Until it doesn't.
An example:
- integration library with multiple DataContract/DataMember models for Core.WCF
- "Trim unused code" trims away setters as it considers setters are not used
- WCF initializer throws InvalidDataContractException: No get method for property 'Foo' in type 'Bar'
- 3 hours wasted on debugging this
Yes, you can possibly add some code to a list of trimmer exceptions. And yes, you have to know that the trimmer is the culprit, in the first place.
