I have a lot of development experience, but this is my first .Net app and I'm having troubles understanding how/what I need to do.

I want to simply add the stock quantity to the product display.  I think I know where to do this (NopCommerceStore\Templates\Products\OneVariant.ascx.cs), but I cannot seem to get my changes to work.

I'm using VS2010 Pro and have recompiled and copied NopCommerceStore.dll and NopCommerceStore.pdb to the Bin folder, but nothing changes...  

Can anyone help me get my head around how to make mods?  What I need to modify/compile/copy over/etc?

Thanks!
