Hi everyone! I am playing with unity native plugins. However, as the title suggested, I encounter the strange dll not found issue. I only got error when I try to run it as a standalone windows app. From editor, it works fine. And I have verified the dll exist in Appname_Data/Plugin directory in my standalone app. Some basic information that might help diagnose this issue: platform: window 8.1 dev tool: vs 2015 The dll (test.dll) is produced by visual studio 2015 (debug and x64). It depends on many other dlls which I copied along with test.dll into my unity project. The dll load perfectly fine if I run the app from unity Editor but failed if build and run it as a standalone 64 bit windows app. Has anyone seen the same issue before? Is this a bug in Unity or am I doing something wrong? Thanks!
