I think I figured out the continual confusion here. The colon is always correct when reading from ASP.NET config JSON. However, when using UserSecrets, the secret can be stored as either
ConnectionString.Foo
orConnectionString:Foo
. We showed examples using periods, which then works when looking up with periods. But then this doesn't work for connection strings from configuration, even though the document makes the assumption that these things work the same.The fix here is to use colons consistently. I also plan to update more of the connection strings documentation at a later time. But many people have hit this, so wanted to fix it now.
