System.DirectoryServices is not recognised in the namespace 'System'

Question

I\'m trying to use System.DirectoryServices in a web site project and I\'m getting this error:

The type or namespace name \'DirectoryServices

Answer 1

This is a very old thread but just to provide a complete answer for the sake of posterity ;)

This issue occurs if the project is missing a reference to the .Net Component System.DirectoryServices

Adding this reference in the usual manner prefered by you will resolve the issue.
