Microsoft Net Framework 4.6 1 Targeting Pack Download

[Jenn Smotherman]

InVisual Studio, you can specify the version of .NET that you want your project to target. Framework targeting helps guarantee that the application uses only functionality that is available in the specified framework version. For .NET Framework apps to run on another computer, the framework version that the application targets must be compatible with the framework version that's installed on the computer.

A Visual Studio solution can contain projects that target different versions of .NET. However, note that you can only build against a single version of .NET either using reference conditionals for a single build or recursively build different binaries for each version. For more information about target frameworks, see Target frameworks.

It filters items in the Add New Item dialog box, the Add New Reference dialog box, and the Add Service Reference dialog box to omit choices that aren't available in the targeted version.

It filters custom controls in the Toolbox to remove those that aren't available in the targeted version and to show only the most up-to-date controls when multiple controls are available.

In an existing Visual Basic, C#, or F# project, you change the target .NET version in the project properties dialog box. For information about how to change the target version for C++ projects, see How to modify the target framework and platform toolset instead.

If your code contains references to a different version of the .NET than the one that you targeted, error messages may appear when you compile or run the code. To resolve these errors, modify the references. See Troubleshoot .NET targeting errors.

When you create a .NET Framework project, you can select the target .NET Framework version after you select a project template. The list of available frameworks includes the installed framework versions that are applicable to the selected template type. For non-.NET Framework project templates, for example .NET Core templates, the Framework drop-down list doesn't appear.

For .NET Framework projects, the Add Reference dialog box disables system assemblies that don't pertain to the target .NET Framework version so that they can't be inadvertently added to a project. (System assemblies are .dll files that are included in a .NET Framework version.) References that belong to a framework version that's higher than the targeted version won't resolve, and controls that depend on such a reference can't be added. If you want to enable such a reference, reset the .NET Framework target of the project to one that includes the reference.

When you target the .NET Framework 3.5 or later, a reference to System.Core and a project-level import for System.Linq (in Visual Basic only) are added automatically. If you want to use LINQ features, you must also turn Option Infer on (in Visual Basic only). The reference and import are removed automatically if you change the target to an earlier .NET Framework version. For more information, see Work with LINQ.

I'm working with an old legacy project that uses .NET Framework v4.0 but I'm having trouble with running it. I cannot update the target framework because this is a massive legacy project that many people rely on. Whenever I try to start up the project I get this dialogue box telling me that I need the .NET Framework 4.0 targeting pack, but when I try to download and install, my system tells me I already have it. Anyone have any ideas for how I can fix this?

Edit:Someone linked another article How to install .NET 4 Framework in Windows 10 but this does not work for me. First, I already have .NET Framework 4.6 installed, and second the download link for the 4.0.3 multi targeting pack no longer works. When I click on the link, it leads me to this article. I tried to click this download link, and it led me to a default store page with nothing to download. Additionally, the article is about Visual Studio 2010, but I am currently using version 2022.

Installing only the Microsoft.NETFramework.ReferenceAssemblies.net40 assembly via nuget did not work for me as this alone would not give me the option to target the .NET 4 framework in Visual Studio 2022. What worked for me is to download the Visual Studio 2019 web installer and install only the ".NET Framework 4.0 targeting pack".

I solved downloading NETFramework.ReferenceAssemblies.net40 unpak it or rename as .zip then copy content from build\.NETFramework\v4.0\ to C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0

I could not download visual studio 2019 because I had already installed visual studio 2022 and I did not want to uninstall it. The visual studio build tools 2019 appeared to be unavailable to install so the solution that worked was downloading the reference Assemblies for NETFramework 4.0 in NugetOrgSite.

Then, after downloading package in the 'About' tab, I simply changed the downloaded package extension to .zip and accessed inside the new zip folder to Downloads\microsoft.netframework.referenceassemblies.net40.1.0.3.zip\build\.NETFramework\v4.0 and copy all folder content to C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0. Then, when I restarted the project in visual studio 2022, the .NET Framework 4 was available to use.

I'm having some issues creating a project that targets .NET Framework 4.8. I am using Visual Studio 2019, upgraded to version 16.2.5. I have also installed the .NET Framework 4.8 Developer Pack. From the Visual Studio Installer, I don't see any option for enabling 4.8 development tools similar to 4.7.

Just thought I'll post my issues as I stumbled across this too with VS2019 Winforms project, and couldn't target anything apart from .Net 5 and Core 3.1. Turns out there're 2 types of Winforms, Winforms App and Winforms App (.Net Framework). The former won't be able to target the other .net framework. The latter is able to. Duh! Simple stuffs that aren't obvious.

In Visual Studio Installer, that can be accessed by clicking on "Tools / Get Tools and features" in the top menu, I selected the "Individual Component" tab and checked ".Net Framework 4.8 Targeting pack". That fixed it for me.

This Visual Studio thread had all the answers I was looking for. The .NET Framework 4.8 Developer Pack includes both the SDK and Targeting Pack. After installing this and restarting Visual Studio, I can now see .NET Framework 4.8 as a targeting option for Visual Studio projects. You should not need to do any Visual Studio Installer steps.

For anybody having this issue in VS 2019 Community edition. The problem in my case was confusion over which template to select. Templates for .NET Framework are in parenthesis and lower in the list (not showing at all in my case until I clicked the "clear" link next to the search box).

I wound up having to re-create my VS project. For template, I found framework 4.8 through searching templates in project creation using framework c# console search params. I then copied my files over to the new project folder, and added them as existing items through the solution tool.

I have found a solution: If I want Visual Studio Community 2019 to target .NET 4.8, I can create some simple projects by using Visual Studio Express 2013. In the Project settings I change the required .NET (up to 4.8) and save. After that, you can open that project with Visual Studio Community 2019 and you will see in the Project settings all .NET target options up to 4.8.

If you don't see the Windows Forms App (.NET Framework) template, youcan install it from the Create a new project window. In the Notfinding what you're looking for? message, choose the Install moretools and features link.

You can install .NET Framework 4.8.1 from our .NET Framework Download site. For building applications targeting .NET Framework 4.8.1, you can download the NET Framework 4.8.1 Developer Pack. If you just want the runtime, you can use either:

.NET Framework 4.8.1 includes native support for the Arm64 architecture (Windows 11+) and accessibility improvements as well as other improvements. You can see the complete list of improvements in the .NET Framework 4.8.1 release notes.

.NET Framework 4.8.1 adds native Arm64 support to the .NET Framework family. So, your investments in the vast ecosystem of .NET Framework apps and libraries can now leverage the benefits of running workloads natively on Arm64 for better performance when compared to running x64 code emulated on Arm64.

In this release, both Windows Forms and WPF have made improvements to the handling of tooltips to enable them to be more accessible. In both cases, tooltips now comply with the guidelines setforth in the WCAG2.1 content on Hover or Focus guidance. The requirements for tooltips require the following:

In WinForms, this support is only available on Windows 11 or higher operating system. WinForms is a thin managed wrapper around the Windows API, and the new tooltip behavior only became available in Windows 11. WPF has no operating system version dependencies for their accessible tooltips.

WPF had implemented most of the requirements for WCAG2.1 compliant tooltips in .NET Framework 4.8. In this release WPF improved the experience by ensuring that a tooltip in the current window can easily be dismissed by using the ESC key, the CTRL key (by itself), or by the combination Ctrl+Shift+F10. The scope of the Escape key was reduced in this release to apply only to the current window, when previously it would have been any open tooltip in the application.

Did the system requirements change? In this blog post it lists Windows Server 2022 as the only supported server OS. But .NET 4.8 supports Windows Server 1803+, Server 2019 and Server 2022. Did a patch release of 4.8 just drop support for an entire family of server products?

.NET Framework 4.8.1 is also available on Windows 10 versions (20H2+) and Server 2022+ for x64 based devices. We realize that some customers need to stay on older OS versions for longer, so we plan to continue to support 4.8 on those OS versions for as long as the OS is in support. This means you can stay on 4.8 with the confidence that you will be fully supported with security, reliability, and compatibility fixes on 4.8 just like you would with 4.8.1.
