Sharing methods between projects

Hello,

I have a single solution in my VisualStudio. Under this solution I have multiple projects and I have custom VB classes, ASP.net forms etc. However if I want to use the public methods of one VB class in Project A in another class in Project B it does not seem to work. During compile time it gives me an error saying that the referenced class is not visible. All methods and classes have been declared with the modifier public. They are not in any namespace

Any help would be appreciated. Thank Youcompile shared methods into a library assembly and then import this into each project.
