I have a project that uses a DLL that I have created. Everything works

  • 0

I have a project that uses a DLL that I have created. Everything works wonderfully, but I am now extending the library in the DLL to optimize some older functions.

What I was wondering is if I just modify the library to where only the main function body changes and nothing else can I just rebuild the DLL and replace it with the old one or is it because the function body changed I need to rebuild any projects that used this DLL.

The main reason I asked is because all of these projects have me referencing the .lib file and to be honest I am not sure what is exactly in a .lib file of a DLL project.

Any advice would be greatly appreciated.

Thanks

    If you’re just changing the functions to optimize them, without changing the function signatures, then you can just build your library and deploy it (replacing the old library).

    However, if you need to change the function signatures then you can do one of (at least) two things:

    1. Modify the code that’s using your library to use the new function signatures.
    2. If #1 is not an option, then consider leaving the old function and deprecating it. Applications with make use of your latest version will have to avoid using the deprecated methods.
