Can someone please help me get rid of these errors/warnings so I can finish my mod? I'm not entirely sure what I did wrong, I tried deleting the DDLs and re-adding them but it didnt work. I can't find where a duplicate is at?? I'm new to modding fyi!!

Have you succeeded in building a mod previously? I admit that I've never seen that error. In my VS, I see the dlls under References under the project in the sidebar. What do you see there?

No this is my first ever mod I've created.
I was able to fix all of the errors but now I have a few warnings showing up. Here they are:
(When I fixed the errors it allowed me to build the solution and continue but when I try to load the mod into my game my game just crashes.)

Those are still indicators that you've added those DLLs twice.
