If you use Visual Studio IDE, you can select references forlder then select add reference and finally select the assembly you want to reference.

Hi,

Why are you copying it into the framework directory?
I think it;s better to install it in the GAC.

You also need to add a reference to it in your project

It doesn't "need" to be installed anywhere.

All that needs to be done is add a reference to the dll by right
clicking references, selecting add reference, and locating the dll on
your hard drive. VS will then make a local copy of this dll in its bin
folder.

You CAN install it in the gac if you WANT... but unless you have a
reason to (reasons being the dll will be shared among many
applications, and as it evolves it may break compatability), i dont see
a reason to bother.
