Why netfx4sdk

netfx4sdk allows you to use easily a deprecated SDK for modern toolsets and IDEs such as VS2022+ / MSBuild 17+ / and other tools without installing any other outdated versions of Visual Studio.

Microsoft officially dropped support of the Developer Pack (SDK) for .NET Framework 4.0. Now it can only be a Runtime version: https://dotnet.microsoft.com/en-us/download/visual-studio-sdks

Means you can't simply build anything along with pure VS2022 (e.g. VM image, clean VS2022 env)

MSB3644: The reference assemblies for .NETFramework,Version=v4.0 were not found. To resolve this, install the Developer Pack (SDK/Targeting Pack) for this framework version or retarget your application. You can (*no, you can't) download .NET Framework Developer Packs at https://aka.ms/msbuild/developerpacks

But netfx4sdk will try to eliminate this artificial limitation by a single command,

• Here's result using netfx4sdk 1.0 for the same clean VS2022 VM image above.

Usage

-mode sys - Hack using assemblies for windows. Highly recommended because

• [++] All modules are under windows support.
• [+] It does not require internet connection (portable).
• [+] No decompression required (faster) compared to package mode.
• [-] This is behavior-based hack;

-mode package will try to apply obsolete package to the environment.

• [-] Officially dropped support since VS2022.
• [-] Requires internet connection to receive ~30 MB via GetNuTool.
• [-] Requires decompression of received data to 178 MB before use.
• [+] Well known official behavior.
