In case you missed it - and because @Zuhair doesn't seem to want to post an answer - here is a copy paste of their solution (I missed this at first as it was only in a comment):

I found the solution. I changed the name of the Web.config to app.config and I was able to get the connection string using:

System.Configuration.ConfigurationManager.ConnectionStrings["SHOPPINGCNN"].ConnectionString

The app.config file looks like this:

 encoding="utf-8" ?> 
 
 
 
 

You also need to install this NuGet package:

System.Configuration.ConfigurationManager

In my case I simply renamed the web.config containing the connectionString 'app.config' and it worked.

I realise this probably isn't a good long term solution but for mixed legacy projects - or to get a foot in the door to begin to learn .net Core it's very useful.
