    I have converted a project from 4.6.2f to 5. Everything is working except for sqlite3. No matter what platform I build for or when I run in the editor I get the error "DllNotFoundException: sqlite3.dll".

    Thanks

    Maybe one of the sqlite3.dll dependencies are missing? Also could you copy-paste the full error message, it should say something about GetDllDirectory.

    The full error message is below. This same setup worked fine with 4.6.2 so the dependencies should all be there.

    I haven't heard about such problem before, could you create a bug with repro case attached and paste the case number (not the link) here.

    Not sure what's wrong, but it seems you need to change
    [DllImport("sqlite3.dll")] to [DllImport("sqlite3")]

    That fixed the issue. I was able to test the editor and android. Thank you very much for the help.
