.NET Core SDK

This repo contains the source code for the cross-platform .NET Core SDK. It aggregates the .NET Toolchain, the .NET Core runtime, the templates, and the .NET Core Windows Desktop runtime. It produces zip, tarballs, and native packages for various supported platforms.

Looking for released versions of the .NET Core tooling?

Download released versions of the .NET Core tools (CLI, MSBuild and the new csproj) at https://dot.net/core.

Build .NET installer

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

• build for basic build

• build -pack to build the installer

• To build in VS, run a command line build first, then run artifacts\core-sdk-build-env.bat from a VS command prompt and then devenv 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 1046 using the LCID of the language you want to test

Build .NET from source (source-build)

This repo also contains code to help you build the entire .NET product end-to-end from source (often referred to as source-build), even in disconnected/offline mode. Please see the dotnet/source-build repo for more information.

Support

.NET Source-Build is supported on the oldest available .NET SDK feature update, and on Linux only. For example, if both .NET 6.0.1XX and 6.0.2XX feature updates are available from dotnet.microsoft.com, Source-Build will only support 6.0.1XX. For the latest information about Source-Build support for new .NET versions, please check our GitHub Discussions page for announcements.

Prerequisites

The dependencies for building .NET from source can be found here.

Building

1. 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.

2. 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
   

   On arm64, please use ./prep.sh --bootstrap instead. This issue is being tracked here.

3. 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-6.0.100-fedora.33-x64.tar.gz.

   Optionally add the --online flag 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 --help to see more information about supported build options.

4. (Optional) Unpack and install the .NET SDK

   mkdir -p $HOME/dotnet
   tar zxf artifacts/x64/Release/dotnet-sdk-6.0.100-fedora.33-x64.tar.gz -C $HOME/dotnet
   ln -s $HOME/dotnet/dotnet /usr/bin/dotnet
   

   To test your source-built SDK, run the following:

   dotnet --info

Installers and Binaries

You can download the .NET Core SDK as either an installer (MSI, PKG) or a zip (zip, tar.gz). The .NET Core SDK contains both the .NET Core 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.

For .NET 7 builds

<configuration>
  <packageSources>
    <add key="dotnet7" value="https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet7/nuget/v3/index.json" />
  </packageSources>
</configuration>

For .NET 6 builds

<configuration>
  <packageSources>
    <add key="dotnet6" value="https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet6/nuget/v3/index.json" />
  </packageSources>
</configuration>

For .NET 6 Optional workloads The below feed is needed for 6.0 releases before RC1

We strongly recommend using --skip-manifest-update with dotnet workload install as otherwise you could pick up a random build of various workloads as we'll automatically update to the newest one available on the feed.

<configuration>
  <packageSources>
    <add key="maui" value="https://pkgs.dev.azure.com/azure-public/vside/_packaging/xamarin-impl/nuget/v3/index.json" />
  </packageSources>
</configuration>

Make sure to run the table generator test and make any changes to the generator along with your changes to the table. Daily servicing builds have been removed as all servicing is done in private repos to avoid disclosure of critical security fixes. All public servicing builds can be downloaded at http://aka.ms/dotnet-download.

Reference notes:

1: Our Debian packages are put together slightly differently than the other OS specific installers. Instead of combining everything, we have separate component packages that depend on each other. If you're installing the SDK from the .deb file (via dpkg or similar), then you'll need to install the corresponding dependencies first:

• Host, Host FX Resolver, and Shared Framework
• ASP.NET Core Shared Framework

.NET Core SDK 2.x downloads can be found here: .NET Core SDK 2.x Installers and Binaries

Sources for dotnet-install.sh and dotnet-install.ps1 are in the install-scripts repo.
