Install .NET on Windows
In this article, you'll learn how to install .NET on Windows. .NET is made up of the runtime and the SDK. The runtime is used to run a .NET app and may or may not be included with the app. The SDK is used to create .NET apps and libraries. The .NET runtime is always installed with the SDK.
The latest version of .NET is 5.0.
The following table is a list of currently supported .NET releases and the versions of Windows they're supported on. These versions remain supported until either the version of .NET reaches end-of-support or the version of Windows reaches end-of-life.
Windows 10 versions end-of-service dates are segmented by edition. Only Home, Pro, Pro Education, and Pro for Workstations editions are considered in the following table. Check the Windows lifecycle fact sheet for specific details.
+ symbol represents the minimum version.

The following versions of .NET are ❌ no longer supported:
The runtime is used to run apps created with .NET. When an app author publishes an app, they can include the runtime with their app. If they don't include the runtime, it's up to the user to install the runtime.
There are three different runtimes you can install on Windows:
ASP.NET Core runtime
Runs ASP.NET Core apps. Includes the .NET runtime.
Runs .NET WPF and Windows Forms desktop apps for Windows. Includes the .NET runtime.
This runtime is the simplest runtime and doesn't include any other runtime. It's highly recommended that you install both ASP.NET Core runtime and Desktop runtime for the best compatibility with .NET apps.
The SDK is used to build and publish .NET apps and libraries. Installing the SDK includes all three runtimes: ASP.NET Core, Desktop, and .NET.
The following Windows versions are supported with .NET 5.0:

|Windows 10 Client||Version 1607+||x64, x86, ARM64|
|Windows Client||7 SP1+, 8.1||x64, x86|

Windows 7 / Vista / 8.1 / Server 2008 R2 / Server 2012 R2
More dependencies are required if you're installing the .NET SDK or runtime on the following Windows versions:
|Windows 7 SP1 ESU||- Microsoft Visual C++ 2015-2019 Redistributable 64-bit / 32-bit
- KB3063858 64-bit / 32-bit
- Microsoft Root Certificate Authority 2011 (.NET Core 2.1 offline installer only)
|Windows Vista SP 2||Microsoft Visual C++ 2015-2019 Redistributable 64-bit / 32-bit|
|Windows 8.1||Microsoft Visual C++ 2015-2019 Redistributable 64-bit / 32-bit|
|Windows Server 2008 R2||Microsoft Visual C++ 2015-2019 Redistributable 64-bit / 32-bit|
|Windows Server 2012 R2||Microsoft Visual C++ 2015-2019 Redistributable 64-bit / 32-bit|
The previous requirements are also required if you receive an error related to either of the following dlls:
Install with PowerShell automation
The script defaults to installing the latest long term support (LTS) version, which is .NET Core 3.1. You can choose a specific release by specifying the
Channel switch. Include the
Runtime switch to install a runtime. Otherwise, the script installs the SDK.
dotnet-install.ps1 -Channel 5.0 -Runtime aspnetcore
Install the SDK by omitting the
-Runtime switch. The
-Channel switch is set in this example to
Current, which installs the latest supported version.
dotnet-install.ps1 -Channel Current
Install with Visual Studio
If you're using Visual Studio to develop .NET apps, the following table describes the minimum required version of Visual Studio based on the target .NET SDK version.
|.NET SDK version||Visual Studio version|
|5.0||Visual Studio 2019 version 16.8 or higher.|
|3.1||Visual Studio 2019 version 16.4 or higher.|
|3.0||Visual Studio 2019 version 16.3 or higher.|
|2.2||Visual Studio 2017 version 15.9 or higher.|
|2.1||Visual Studio 2017 version 15.7 or higher.|
If you already have Visual Studio installed, you can check your version with the following steps.
- Open Visual Studio.
- Select Help > About Microsoft Visual Studio.
- Read the version number from the About dialog.
Visual Studio can install the latest .NET SDK and runtime.
Select a workload
When installing or modifying Visual Studio, select one or more of the following workloads, depending on the kind of application you're building:
- The .NET Core cross-platform development workload in the Other Toolsets section.
- The ASP.NET and web development workload in the Web & Cloud section.
- The Azure development workload in the Web & Cloud section.
- The .NET desktop development workload in the Desktop & Mobile section.
Install alongside Visual Studio Code
Visual Studio Code is a powerful and lightweight source code editor that runs on your desktop. Visual Studio Code is available for Windows, macOS, and Linux.
While Visual Studio Code doesn't come with an automated .NET Core installer like Visual Studio does, adding .NET Core support is simple.
- Download and install Visual Studio Code.
- Download and install the .NET Core SDK.
- Install the C# extension from the Visual Studio Code marketplace.
The download page for .NET provides Windows Installer executables.
When you use the Windows installers to install .NET, you can customize the installation path by setting the
dotnet-sdk-3.1.301-win-x64.exe DOTNETHOME_X64="F:\dotnet\x64" DOTNETHOME_X86="F:\dotnet\x86"
If you want to install .NET silently, such as in a production environment or to support continuous integration, use the following switches:
Prevents any UI and prompts from displaying.
Suppresses any attempts to restart.
dotnet-sdk-3.1.301-win-x64.exe /install /quiet /norestart
For more information, see Standard Installer Command-Line Options.
The installer returns an exit code of 0 for success and an exit code of 3010 to indicate that a restart is required. Any other value is generally an error code.
Download and manually install
As an alternative to the Windows installers for .NET, you can download and manually install the SDK or runtime. Manual install is usually done as part of continuous integration testing. For a developer or user, it's generally better to use an installer.
Both .NET SDK and .NET Runtime can be manually installed after they've been downloaded. If you install .NET SDK, you don't need to install the corresponding runtime. First, download a binary release for either the SDK or the runtime from one of the following sites:
Create a directory to extract .NET to, for example
%USERPROFILE%\dotnet. Then, extract the downloaded zip file into that directory.
By default, .NET CLI commands and apps won't use .NET installed in this way and you must explicitly choose to use it. To do so, change the environment variables with which an application is started:
set DOTNET_ROOT=%USERPROFILE%\dotnet set PATH=%USERPROFILE%\dotnet;%PATH% set DOTNET_MULTILEVEL_LOOKUP=0
This approach lets you install multiple versions into separate locations, then explicitly choose which install location an application should use by running the application with environment variables pointing at that location.
DOTNET_MULTILEVEL_LOOKUP is set to
0, .NET ignores any globally installed .NET version. Remove that environment setting to let .NET consider the default global install location when selecting the best framework for running the application. The default is typically
C:\Program Files\dotnet, which is where the installers install .NET.
Containers provide a lightweight way to isolate your application from the rest of the host system. Containers on the same machine share just the kernel and use resources given to your application.
.NET can run in a Docker container. Official .NET Docker images are published to the Microsoft Container Registry (MCR) and are discoverable at the Microsoft .NET Docker Hub repository. Each repository contains images for different combinations of the .NET (SDK or Runtime) and OS that you can use.
Microsoft provides images that are tailored for specific scenarios. For example, the ASP.NET Core repository provides images that are built for running ASP.NET Core apps in production.
