I have developed the assembly in visual studio, but am coding the pages in Notepad++, as visual studio is just way to bloated for my liking.

I have not included an App_Code or App_References, as I thought the only folder required was Bin.

I will do some research on the App_References folder. Both assembly and ASP.NET website are .NET 2.0.

Thanks for your help, do you have any other suggestions?
