nuget.config is ending up in my output directory

[richlander]

I am building this app (in containers) and nuget.config is ending up in the output. I cannot tell why.

https://github.com/dotnet/dotnet-docker/tree/main/samples/releasesapi

I have tried other apps and it isn't happening. There must be some nuance that I cannot see.

There are **\*.config wildcards in some SDK files, like here:

sdk/src/StaticWebAssetsSdk/Sdk/Sdk.StaticWebAssets.StaticAssets.ProjectSystem.props

Lines 38 to 40 in 5cd429e

	<!-- When ExcludeConfigFilesFromBuildOutput is set, do not copy .,config, .json files to the build output directory. -->
	<Content Include="**\*.config" ExcludeFromSingleFile="true" CopyToPublishDirectory="PreserveNewest" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder);$(DefaultWebContentItemExcludes)" Condition="'$(ExcludeConfigFilesFromBuildOutput)'=='true'" />
	<Content Include="**\*.json" ExcludeFromSingleFile="true" CopyToPublishDirectory="PreserveNewest" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder);$(DefaultWebContentItemExcludes)" Condition="'$(ExcludeConfigFilesFromBuildOutput)'=='true'" />

Does the behaviour change if you add nuget.config to DefaultWebContentItemExcludes or to some other property referenced there? If so, perhaps it should be added by default.

I suppose this only affects projects that are still using nuget.config and have csproj and nuget.config in the same directory, rather than sln and nuget.config in an outer directory.
