Why if I copy the EXE file of a WPF application does it stop working?

Question

Programming

Good afternoon. Tell me, please, why if you copy the compiled exe file of the WPF application and run the copy, it will not work? An example on the screen below:

On the left is the "native" EXE file, on the right is a copy. Those. application themes are gone, there is no connection to the MSSQL server and other delights.
Thanks for the help.

Посмотрите зависимости exe - скорее всего нужно тянуть еще какую то dll или еще какие файлы.
