String resource returned as plain text instead of (declared) data contract

[Philipp Sumi <sumip@…>]

Declaring a string resource as data contract might return plain text rather than XML, probably depending on the ACCEPT headers sent with the request:

ResourceSpace.Has.ResourcesOfType<string>()
  .AtUri(uris.CreateFolderPathUri)
  .HandledBy<FolderPathCreationHandler>()
  .AsXmlDataContract();

Different browsers have different accept headers which impact what content negotiation does. This is by design. Closing.
