How to include gdiplus.dll to a build?

I’m using Aspose.Slide.dll to convert powerpoint shapes and slides to textures. It works fine inside the editor but whan i publish standalone it says : DllNotFoundException: gdiplus.dll

i have found libgdiplus.dylib in Program File(x86)/Unity/Editor/Data/mono/lib/ but no gdiplus.dll in …/Data/mono/lib/mono/2.0/

Does anyone know how to include that gdiplus.dll in the build or any workaround to make it work like a wrapper or something?

Anytime you want to include a .dll into your project you can simply put it in your Assets folder in your project. This way, Unity will import it and it will sync with your mono project as well.
