web.config, configSource, and “The 'xxx' element is not declared” warning

Question

I have broken down the horribly unwieldy web.config file into individual files for some of the sections (e.g. connectionStrings, authentication, pages etc.) using the configSour

Answer 1

I think that you get the blue squiggles since the schema of your web.config file doesn't declare these custom config sections that you've 'broken out' into individual files.

In investigating this, I see that some of my solutions have the same issue, but the config sections that are provided from microsoft DON'T have the squiggles. eg: we have extracted the appsettings and connectionstrings out into their own files, and they don't get the squiggles, but our custom ones do.

I tried to view the microsoft schema at schemas.microsoft.com/.netconfiguration/v2.0, but I get a 404 when trying to download it.

What I'm trying to say is if you get a copy of the MS schema and alter it to include your external config files, you should be able to get rid of the dreaded squiggles!
