How to target .NET Framework 4.0 in VS 2022 on Windows 11?

Working on some old projects targeting .NET Framework 4.0. I used VS 2022 to open the solution and was told to install 4.0 targeting pack.

I can't find the download link on the dotnet website, nor the installation option in Visual Studio Installer.

Anyway to install it?

(Of course I know it's no longer supported. But I cannot just make it target a newer version, because my boss does not let me do that.)

    OK I found a solution. Hope it can help if you are facing the similar problem.

    Just download VS 2019. In the installer check .NET 4 multi targeting pack only (no need to install other payloads). Install.

    Then VS 2022 should be able to build projects targeting 4.0.

    Hi, just download the reference assemblies from nuget.org (click on the "Download package" link) open the file as zip and paste the content of the folder build\.NETFramework\ into Program files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework.

    Hi @Lee Feng ,
    According to Install .NET Framework for developers

    Starting with Visual Studio 2022, Visual Studio no longer includes .NET Framework components for .NET Framework 4.0 - 4.5.1 because these versions are no longer supported. Visual Studio 2022 and later versions can't build apps that target .NET Framework 4.0 through .NET Framework 4.5.1. To continue building these apps, you can use Visual Studio 2019 or an earlier version.

    Best Regards.
    Jiachen Li

    Hello,

    Thanks for posting the query here and I'm happy to help you regarding this Dot NET upgrade.

    If you have VS 2022 installed, it should have included latest dot net versions.

    Please find below link to download load latest version of .Net 4.8.1 - https://dotnet.microsoft.com/en-us/download/dotnet-framework/net48

    Just an observation.

    Although the .NET 4 Multi Targeting Pack is not available to Community Editions, one might notice we can still build existing .NET 4 Framework projects in VB2022 Community Edition. Therefore, take a copy of any old VB project, strip it down to bare bones, and use it as a "Framework4" Project Template to build fresh .NET 4 Framework Class Library projects under VB2019 or VB2022 Community Editions. I use a tiny already-bare-bones test console application and added a form window. This can be easily transformed into a windowed project with quick selections in the project properties.
