You have to turn it into a COM object first.
Have a look at this link on CodeGuru :

Also make sure that you change the assembly version number to a fixed
number...
Initially it is something like
[assembly: AssemblyVersion("0.0.*")]
On each build the build number is increased and then you have to
reselect the new Dll reference from within VB.
Change the version to
[assembly: AssemblyVersion("0.0.1")]
and this problem will be gone.
