Recently I feel very obsessed and in compulsory need to customize file names of predefined assembly, which are:
Assembly-CSharp-firstpass.dll
Assembly-CSharp-Editor-firstpass.dll
Assembly-CSharp.dll
Assembly-CSharp-Editor.dll
into my preference. I don’t mind about mental disorder. Nevertheless, is there any way to make it?
Put all your scripts into assembly definitions. If there are no scripts that don’t belong to an asmdef, then the default Assembly-CSharp-* assemblies won’t be created. For asmdefs, the name of the assembly is the same as the asmdef, so you are free to change the to your liking.
