DotnetEx4

DotnetEx4 is organized in a dotnet/runtime-inspired layout so legacy .NET Framework backports, modern targets, tests, and NuGet packaging have clear ownership and minimal duplicated MSBuild configuration.

Repository layout

  • Directory.Build.props / Directory.Build.targets — root repository controller pair, like dotnet/runtime
  • global.json — repository SDK selection
  • eng/ — central build, target, version, dependency, signing, validation and NuGet controllers
  • src/corelib/ — HFDotnetEx.HFExtensions, the mscorlib/System.Private.CoreLib compatibility layer
  • src/libraries/ — product libraries and runtime/framework backports
  • src/tools/ — repository tools
  • src/shared/ — shared .shproj / .projitems source
  • tests/ — isolated test projects; target-map only, never NuGet packages
  • samples/ — isolated demos; the two downloader demos are intentionally package-eligible
  • DotnetEx4.slnx — canonical solution
  • DOTNETEX4_PROJECT_MAP.txt — complete architecture and agent operating manual

Central-control rule

One setting has one owner. Repository-wide C# 14/default paths/common symbols live in root Directory.Build.props; framework profiles live in eng/TargetFrameworks.props; project registration in eng/Projects.props; dependency routing in eng/Dependencies.props; dependency/product versions in eng/Versions.props; NuGet release version, package selection, IDs, titles and tags in eng/NuGet.Metadata.props; and signing in eng/Signing.props.

The root Directory.Build.* pair is deliberately small. Production folders (src/corelib, src/libraries, src/tools) have scoped Directory.Build.* files that explicitly import the root pair and then the production eng/Build.* chain. Tests and samples have no local Directory.Build.*; they inherit the safe root defaults/target map. Samples remain isolated from production controller imports even when intentionally packed.

Source ownership

For every exact API/target, prefer: native runtime/framework → official Microsoft NuGet package → DotnetEx backport. Never allow duplicate owners for the same API on the same target.

NuGet

The current release version is 4.1.31, controlled only by eng/NuGet.Metadata.props. The central catalog contains 27 packages. Tests and tools are excluded; the two downloader demo samples are intentionally included.

NuGet.org reserves the public Microsoft.* and System.* prefixes. DotnetEx backport packages for those families therefore publish as DotnetEx.Microsoft.* and DotnetEx.System.*, while their official/.Ex identities remain in package Title and Tags. HFDotnetEx.Helpers intentionally keeps its existing package ID.

Before editing

Read DOTNETEX4_PROJECT_MAP.txt. It explains every controller, target profile, production project, package identity, special ownership boundary, test/sample rule, and the exact procedure for adding a new project.
