2. Press the settings link and from the pop-up window select the 'Settings' Tab

3. Uncheck the use this connection string at runtime from all your connection strings.

4. Click Save button to close the window. (No need to Restart Visual Studio)
5. Try to publish the website again, and it should publish without a problem.

NOTE
I am using VS 2017 (and according to the comments this work also in Visual Studio 2013)

Just for Note
After I did the previous steps, I noticed that the .pubxml file changed automatically. here is the difference which has been made (automatically without any interference from me)

So I think this is a better way because it is easier for the developer and also it let the visual studio to solve its problems himself, without forcing it into a specific thing.
