Interested in this!!

I am new to this project, and during my set up process for this project, my Rider IDE warns me the following message: An expression cannot be used in this context because it cannot be passed or returned by reference. However, I can successfully build this project. 

So, I just want to clarify if this is a potential issue that we need to fix? If so, I'd like to give it a try.

This warning may not effect the build result, but I will fix it later.
