[C# - VB.NET] Referenced dll freezes Windows service

I created a dll using vb.net and have been able to use it within my c#
project by referencing it. I have set up event handlers to handle certain
events fired by the dll. This all works great if the c# project is a windows
application. I then tried to use the dll within a windows service with no
luck. When the windows service goes to instantiate the class object using
the dll, it hangs (as is apparent when I debug the running process). The dll
is copied locally and I am not getting any errors. Any suggestions?


Thanks for any help,
