Today I noticed that in my
ConfigurationManager.ConnectionStrings the very first instance is
.\SQLEXPRESS. I remembered explicitly removing this entry from my web.config so I checked again, but didn't find a thing. Then I did a search over my entire solution, not a single match.
Where the hell is this connection string coming from and how can I remove it?
It's in there by default, pulled in from your machine config file. To get rid of it just put
Above your first connection string to remove it.
