We have class library as a project in our solution as well as a web part project.
Our web part simply references and executes a service utility class in the class library and outputs it into a label.
The deployment is successful but when attempting to add the web part to the page, it comes out with a error page saying "File Not Found" with a correlation ID and date/time reference.
Once we take out the code that executes the utility class, it deploys fine and we're able to add it to the page without any issues.
It seems evident that any reference to our class library causes this "File Not Found" issue... but we're not sure how to implement this solution.
Do we add the class library dll directly into the GAC? If so, how?
Is there another reference we have to implement in the AssemblyInfo.cs? If so, what does that look like?
Any help is appreciated.
