How to make .dll files work?

So i downloaded a radar script from lspdfr i have seen other scripts like spike strips v and its .net.dll and i did that and the config.ini and i added it like frfuel has it and spike strips in the __resource.lua but it wouldn’t load in for some reason
would anyone know why?

WARNING:::: (offtopic)

isn’t this the code to add in server.lua to convert cfx to fx

    if sep == nil then
        sep = "%s"
    end
    local t={} ; i=1
    for str in string.gmatch(inputstr, "([^"..sep.."]+)") do
        t[i] = str
        i = i + 1
    end
    return t
end

You should read the replies to this topic Important question about limits for server

Also, for string splitting, read the FX server porting notes on the wiki. It will tell you what has changed.
