At first, I've already confirmed that DLL work well by using C# WPF project.
Then I bring those DLL into Unity project, and confirmed "there is no error message".
But the problem is that DLL doesn't work at all.(Function return NULL)
I've tried to modify below configuration options, but the situation doesn't change.
(Build Setting→Player Setting→Other Setting →Configuration)
- Runtime version : 4.0 -> 3.5 (rebuild but NG)
- Scripting Backend : Mono->IL2CPP ( Still NG)
- Api Compatibility : 4.0 -> 2.0 (still NG)
Do you have any advice about this problem.
Thank you in advance.
