Hello! I am attempting to include the following .NET Standard 2.0 libraries through a csc.rsp file. I am using Unity 2018.3.6f1, with IL2CPP/.NET Standard 4.x scripting. I have the following file in my \assets folder: csc.rsp Here's the resulting error on play: OK, so then I try removing System.ServiceModel.Primitives.dll but I can see my .NET Standard 2.0 WCF services require it. I'm totally confused as to what the workflow is to get this to work properly. What am I missing? What works is dropping the DLLs I need into the \Assets folder. I understand that I should not do this... Separate but related -- is there some kind of quirk in Unity where I must close the editor and re-open it for csc.rsp changes to work? Also -- when do I use csc.rsp vs mcs.rsp? The documentation on the Unity website shows mcs.rsp but build warnings request csc.rsp. Are the docs out-of-date? *edited to correct folder name assemblies are placed in.
