LNK4075: ignoring '/EDITANDCONTINUE' due to '/OPT:ICF' specification

c++ visual-studio dll linker linker-warning

I recently converted a multi-project Visual Studio solution to use .dlls instead of .libs for each of the projects. However, I now get a linker warning for each project as stated in the example. MSDN didn't serve to be all that helpful with this. Why is this and how can I solve it?

You can either have "Edit and continue" support or optimizations. Usually, you put "Edit and continue" on debug builds, and optimizations on release builds.

Edit and continue allows you to change code while you are debugging and just keep the program running. It's not supported if the code also has to be optimized.
