Why am I unable to access "System.DirectoryServices" from any namespace but my presentation layer?

Question

I am accessing active directory with the System.DirectoryServices library, currently in my web layer. However, I'm trying to move a function from a code-behind file to a VB class in another namespace, and I cannot seem to access that class from within that namespace. What gives?!

Answer 1

I guess the class you're trying to move the logic to is inside of another project?

If this is the case you need to add a reference to the System.DirectoryServices assembly on that project.
