Deploying very simple macro Follow

Hi,

I need to create new template macro that would change CamelCase names to names separated with underscore. 

Like this: 

ThisIsCamelCase --> this_is_camel_case. 

This is the code I wrote: 

namespace ResharperExt
{
   [MacroDefinition("Pascal case to db table column")]
   public class PascalCaseToDbTableColumnMacroDefinition : SimpleMacroDefinition
   {
   }
}

namespace ResharperExt
{
    [MacroImplementation(Definition = typeof(PascalCaseToDbTableColumnMacroDefinition))]
    public class PascalCaseToDbTableColumnMacro : SimpleMacroImplementation
    {
        private readonly IMacroParameterValueNew myArgument;

        public PascalCaseToDbTableColumnMacro([Optional] MacroParameterValueCollection arguments) {
            myArgument = arguments.OptionalFirstOrDefault();
        }

        public override string EvaluateQuickResult(IHotspotContext context)
        {
            if (myArgument == null) return null;

            string argValue = myArgument.GetValue();
            StringBuilder result = new StringBuilder();
            foreach (char ch in argValue)
            {
                if (Char.IsUpper(ch))
                {
                    if (result.Length > 0)
                    result.Append('_');

                    result.Append(Char.ToLower(ch));
                }
                else
                    result.Append(ch);
            }

            return result.ToString();
        }
    }
}

This compiles successfully after adding jetbrains sdk package as reference. This is where my problems started. I tried to copy plugin dll to multiple folders but nothing happened.

After that I found this: https://www.jetbrains.com/help/resharper/sdk/Extensions/Tools.html

I'm not sure is this really a way to implement this mega turbo tiny simple resharper macro. Another build of resharper, nuget packages, waves, zones?! 

My question is: do I really need to do all this in order to make this extremely simple macro work? Or there is a simpler way? 

Thanks.
