Change Connection String whilst App is running

Hi all,

I have a requirement to select different databases from a drop down list in an app which would then populate the active database connection string. Is this possible in Asp Core? If so does anyone have any suggestions how I might achieve this?

I have thought about writing the updated conn string to a "dynamic" appsettings file but I think I would need to restart the app for this to be read.

Thanks,

Jus
