And to finish it off the launchsettings.json:

The issues start when I'm using TFS to deploy the application to a remote machine. Whether I'm deploying to my Development server or Test server, the logging is not working. When I'm manually copying the settings from the appropriate appsettings.*.json to the appsettings.json, everything works as expected. The logging is be done in the correct SQL database. Therefore I know the settings are correct. It just looks like my deployment is somehow only picking up the settings from the appsettings.json, not including the settings from the appsettings.*.json. I must be overlooking something, but I can't see what. Hopefully someone can help me with this.

And the launchsettings.json:

[edit] All of the appsettings files (appsettings.json as well as all the appsettings.*.json) have these properties
