Clickonce deploy external dll reference not found

Question

I'm trying to deploy an application written in wpf c#. I use an external library (irrklang). I added a reference in visual studio to that dll (it is placed in the same folder as the executable). It shows up in my application files, I deploy, install on a different machine and I get the file not found exception. I looked up the exe folder and the DLL is in the folder.

What am I doing wrong, the reference seems to be correct but the program isn't finding the dll at all

UPDATE: added solution below. Still same error:(

Answer 1

Check the following points:

• Properties of the DLL -> Use local copy = true
• Project Properties -> ClickOnce Properties -> ApplicationFiles -> Check if your dll is enlisted and manually set "Include" on it.

Then try again. ClickOnce often has annoying bugs.

Answer 2

发现它，外部dll需要visual studio可再发行。
