I need to use 3rd party .net 4.0 dll’s from an Autocad package. I put in a Geometry library as a test. This worked well so i tested an in-house dll that referenced the Autocad dll but this caused it to fail.
Before i commit to porting my project, i want to fully understand what does and does not work so i know if it is even possible with Unity.
My guess would have been that 4.0 dll’s that don’t use 4’s features will work but my dll failed for including another dll that normally does work on its own.
So what is the rules for using 4.0 dll’s? Does referencing them (with minimum use) in a test project and not having errors suggest that it will work for my whole project?
