`Could not load file or assembly 'Mono.Options`

[Stan-Stani]

System.IO.FileNotFoundException: 'Could not load file or assembly 'Mono.Options, Version=5.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.'

If you encounter this issue, you have to change the references to Private: True.

 <Reference Include="Mono.Cecil, Version=0.10.0.0, Culture=neutral, PublicKeyToken=50cebf1cceb9d05e, processorArchitecture=MSIL">

What exactly do I change and where?

[Stan-Stani]

@GoatLeywin ah it's been a while but do a global search ctrl+shift+f in your code and search for <reference Include= and that might help you find the file.

<Private>True</Private> is what you should add, I believe.
