It marks lines in red, but it compiles.

Question

In Visual Studio 2022 with the latest update and C#, I use two DLLs. In the first DLL, I removed an enumeration and created another one, which I compiled. In the second DLL, it also compiles, but the lines where I reference the new enumeration are highlighted in red.

Answer 1

If you move code between projects you need to do a clean and rebuild to remove any partial compile artifacts.
