I have a problem. I have inserted parts of an already existing program into our program. I have adjusted all references, nuggets, namespaces etc and the program is already running on my PC. Then when I passed it to our tester, it crashed. The reason is that it does not find the System.Drawing.dll. While troubleshooting, I found out that this dll is in my GAC. After deleting it, the program crashed on my PC as well. In the referenced folder is the System.Drawing.dll. I don't understand why the program is trying to load it from the GAC and not from the referenced folder.
I have tried several solutions from other threads. E.g. copy locally = true, set specifc version = true,
Additionally, I tried putting the DLL directly into the output folder. In doing so, I noticed that the program works with dll version 2.0.0.0 and not 4.0.0.0, which is referenced. However, I did not specify a particular version.
Exception message: (sorry for german)

Temporary Solution I created a postbuild event, which copied the System.Drawing.dll in the output folder. So the program is running now, but I don't like this solution, because it doesn't fix the bug.
