How can Hot Reload be used with an external Assembly in the form of a .dll file?

edit

Hot Reload functionality is only available on certain platforms and with certain programming languages. However, assuming the platform and language are configured correctly, it is possible to use Hot Reload with an external assembly in the form of a .dll file by following these steps:

1. Ensure that the .dll file is built as a Debug version with Debug symbols.

2. Add a reference to the .dll file in your main application project.

3. Start your application in Debug mode.

4. Make the desired changes to your code and save the changes.

5. The changes made to your code should now be reflected in the running application without needing to stop and start the application again.

Note that certain changes may not be eligible for Hot Reload and may require stopping and restarting the application. Also, while some platforms and programming languages support full Hot Reload functionality, others may only allow for limited hot reloading feature, such as only being able to refresh certain parts of the application.
