    /in <file>           - Specifies input filename (optional)
    /out <file>          - Specifies output filename (optional with native images,
                           required with MDIL)
    /MissingDependenciesOK - Specifies that crossgen should attempt not to fail if a dependency is missing.
    /Trusted_Platform_Assemblies <path[;path]>
                         - List of assemblies treated as trusted platform
    /Platform_Resource_Roots <path[;path]>
                         - List of paths containing localized assembly directories
    /App_Paths <path>    - List of paths containing user-application assemblies and resources
    /App_Ni_Paths <path[;path]>
                         - List of paths containing user-application native images
                         - Must be used with /CreatePDB switch
                         - List of paths containing target platform WinMDs used for emulating
