In 8.0 I have a .vi that uses a .NET assembly with a class that communicates with the embedded SW in my HW device. This works just fine, I can 'see' and use all of the methods and properties available in this class. Now that I've gone over to 8.20 the .vi no longer works. I the property and method nodes have no available methods or properties??? I am also using another client class that is working just fine even in 8.20? Anyone else seen anything like this?
