-### Microsoft.Azure.Functions.Worker.Sdk 1.17.0-preview1 (meta package)
-
-- Improve incremental build support for worker extension project inner build (https://github.com/Azure/azure-functions-dotnet-worker/pull/1749) 
-  - Now builds to intermediate output path
-- Resolve and pass nuget restore sources as explicit property to inner build (https://github.com/Azure/azure-functions-dotnet-worker/pull/1937)
-- Integrate inner build with existing .NET SDK targets (https://github.com/Azure/azure-functions-dotnet-worker/pull/1861)
-  - Targets have been refactored to participate with `CopyToOutputDirectory` and `CopyToPublishDirectory` instead of manually copying
-  - Incremental build support further improved
