Hello Danny,

what's the type of asp.net project on your dev machine - file or IIS?!
Seems that IIS. Have u tried to restart IIS after you build new version of
your assembly and before running site on dev?!

if it doesnt help, try to remove everything from c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary
ASP.NET Files\

seems that IIS load your new assembly to others, which were not flushed and
new changed are not correcly used
