This repo contains the source code for the cross-platform .NET SDK. It aggregates the .NET toolchain, the .NET runtime, the templates, and the .NET Windows Desktop runtime. It produces zip, tarballs, and native packages for various supported platforms.
The links below are for preview versions of .NET tooling. Prefer to use released versions of the .NET tools? Go to https://dot.net/download.
.NET Framework is the product from which the .NET Core project originated. .NET Core (mostly just called ".NET" here) adds many features and improvements and supports many more platforms than .NET Framework. .NET Framework remains fully supported and you can find the downloads on the .NET website. For new projects, we recommend you use .NET Core.
This repo is for the installers. Most of the implementation is in other repos, such as the dotnet/runtime repo or the dotnet/aspnetcore repo and many others. We welcome you to join us there!
You can consult the Documents Index for the SDK repo to find out current issues, see workarounds, and to see how to file new issues.
This project has adopted the code of conduct defined by the Contributor Covenant to clarify expected behavior in our community. For more information, see the .NET Foundation Code of Conduct.
The repository contains native code project required for the Windows installer. If you intend to build it locally on Windows, you will need to ensure that you have the following items installed.
-
Install CMAKE 3.21.0 is required if you're building VS 17.0. Make sure to add CMAKE to your PATH (the installer will prompt you).
-
Install MSVC Build tools for x86/x64/arm64, v14.28-16.9
-
buildfor basic build -
build -packto build the installer -
To build in VS, run a command line build first, then run
artifacts\core-sdk-build-env.batfrom a VS command prompt and thendevenv Microsoft.DotNet.Cli.sln -
To test different languages of the installer, run
artifacts\packages\Debug\Shipping>dotnet-sdk-3.1.412-win-x64.exe /lang 1046using the LCID of the language you want to test
Please see the dotnet/source-build repo for more information.
.NET Source-Build is supported on the oldest available .NET SDK feature update for each major release, and on Linux only. For example, if .NET 6.0.1xx, 6.0.2xx, and 7.0.1xx feature updates are available from dotnet.microsoft.com, Source-Build will support 6.0.1xx and 7.0.1xx. For the latest information about Source-Build support for new .NET versions, please check our GitHub Discussions page for announcements.
.NET 8.0 (currently in prerelease) and newer will be built from the dotnet/dotnet repo. Clone the dotnet/dotnet repo and check out the tag for the desired release. Then, follow the instructions in dotnet/dotnet's README to build .NET from source.
-
Create a .NET source tarball.
./build.sh /p:ArcadeBuildTarball=true /p:TarballDir=/path/to/place/complete/dotnet/sources
This fetches the complete .NET source code and creates a tarball at
artifacts/packages/<Release|Debug>/Shipping/. The extracted source code is also placed at/path/to/place/complete/dotnet/sources. The source directory should be outside (and not somewhere under) the installer directory. -
Prep the source to build on your distro. This downloads a .NET SDK and a number of .NET packages needed to build .NET from source.
cd /path/to/complete/dotnet/sources ./prep.sh --bootstrap -
Build the .NET SDK
./build.sh --clean-while-building
This builds the entire .NET SDK from source. The resulting SDK is placed at
artifacts/x64/Release/dotnet-sdk-7.0.100-your-RID.tar.gz.Optionally add the
--onlineflag to add online NuGet restore sources to the build. This is useful for testing unsupported releases that don't yet build without downloading pre-built binaries from the internet.Run
./build.sh --helpto see more information about supported build options. -
(Optional) Unpack and install the .NET SDK
mkdir -p $HOME/dotnet tar zxf artifacts/x64/Release/dotnet-sdk-7.0.100-your-RID.tar.gz -C $HOME/dotnet ln -s $HOME/dotnet/dotnet /usr/bin/dotnet
To test your source-built SDK, run the following:
dotnet --info
| Visibility | All legs |
|---|---|
| Public | |
| Microsoft Internal |
You can download the .NET SDK as either an installer (MSI, PKG) or a zip (zip, tar.gz). The .NET SDK contains both the .NET runtime and CLI tools.
Note: Be aware that the following installers are the latest bits. If you want to install the latest released versions, check out the preceding section. With development builds, internal NuGet feeds are necessary for some scenarios (for example, to acquire the runtime pack for self-contained apps). You can use the following NuGet.config to configure these feeds. See the following document Configuring NuGet behavior for more information on where to modify your NuGet.config to apply the changes.
