.well-known folder not published by SDK 2.1.4

Steps to reproduce

Add a .well-known folder and files (such as /.well-known/assetlinks.json) file to the wwwroot of an ASP.NET Core project and publish it.

Expected behavior

The .well-known folder is included in the wwwroot folder output from dotnet publish.

Actual behavior

The .well-known folder is not included.

Environment data

dotnet --info output:

.NET Command Line Tools (2.1.4)

This works in 2.0.3 but does not in 2.1.4.

I’d like an “official won’t-break-again”

fyi I don’t work for MS or .NET Foundation, so nothing I write is official.

My personal suggestion would be to add this in the csproj, without a target:

<ItemGroup>
  <Content Include="wwwroot\.well-known\**" CopyToPublishDirectory="PreserveNewest" Exclude="$(DefaultItemExcludes)" />
</ItemGroup>
