* Deprecate the Microsoft.AspNetCore.App metapackage in favor of targeting and runtime packs
* Stop producing Microsoft.AspNetCore.App, and runtime.$(rid).Microsoft.AspNetCore.App
* Generate the shared framework without using 'NuGet' restore
* Stop producing intermediate packages for shared-framework only assemblies
* Put the platform manifest into the targeting pack (data/Microsoft.AspNetCore.App.PlatformManifest.txt)
* Create well-known, shared intermediate directories that installers can use to bundle content
Changes:
* Add support for a property, `IsAspNetCoreApp`, in the .csproj file of assemblies which are part of the shared framework.
* Remove unused dependencies
* Remove reference which have become part of 'netcoreapp3.0'
This simplifies the way that we publish files to our network drop share.
Changes:
* Instead of explicitly listing every file that needs to publish, use directories to classify packages and artifacts into different categories.
* Add documentation for the expected layout of artifacts/
* Remove the need for static analysis to determine which packages go to which project
* Add the MSBuild property "IsProductPackage" to .csproj files which ship as a package to NuGet.org.
