Assembly load failure about epplus

Did some more experimentation between versions and this happened at version 7.0.3. I can use 7.0.2 just fine but when I move up to 7.0.3 it starts throwing the exception. I also noticed that this is when the package specifically starts targeting .NET 8.0 (which is what Revit 2025 uses hence we do too). It seems like possibly something is off in the 8.0 support?

Hello!

We seem to have issues replicating your issue. Could you create a new project that replicates this error for us to look at?

Ok so after experimenting more it may be something in the way that Revit is loading this. I figured out that my unit tests that run as their own process are passing and exporting successfully in the newer versions as well, even though inside Revit it's not working. I need to delve into it further to see if there is anything else in the unit tests that would cause it to work when the addin application does not. I've also asked Autodesk about this to see if they know why it would be throwing the error. I will see if I can create a reproducible example outside of Revit and get back to you.
