Debugging using Visual Studio

I have gone through all the articles and used AI a bit. Trying to get NinjaTrader9 ninja script to attached Visual Studio and be able to debug my strategy.
I made sure ninja was in debug mode. I recompiled the solution.
I deleted the bin and obj folders from the Custom Folder and recompiled
I went into Debug / modules and attempted to manually load the symbols from the new PDB
In the end it states symbols are loaded but then continually tells me the source code is different. If I uncheck the requirement that it be the same it never steps into the code.
Thoughts? Suggestions? Articles?
