Description of the PR
Fix #3561 (closed)
Previously, the .NET Core SDK would not send configured default headers. This PR fixes this and also "fixes" the strange singular name of the property by marking it obsolete and redirecting to the new correctly-named plural form.
This second change is a separate commit and is less important so I'd drop it if need be.
