  • Documentation content changes

Changes

  • There were two incomplete XML docs for arguments to a SetProperty method
  • The SetProperty<TModel, T>(T, T, TModel, Action<TModel, T>, string?) had an uncostrained type argument TModel. This would've resulted in potential bugs in case the model was a value type, as the instance passed as input to the callback would've been passed by copy, hence the update would've been lost (only the local copy in the callback would've been updated). I've add a where TModel : class constraint to prevent this from happening. I wouldn't expect users to actually try to use that with value types, but anyway the signature is more correct and less error prone now 😄
