Current status
- Targeted release: Fedora 33
- Last updated: 2020-08-03
- FESCo issue: #2453
- Tracker bug: #1863332
- Release notes tracker: #542
Detailed Description
Fedora currently includes .NET Core only on x86_64. We want to make .NET Core available on Aarch64 as well for our users.
.NET Core documentation calls the Linux/aarch64 platform "linux-arm64".
This platform has been supported by upstream .NET Core for a little while now (2 years or so). But upstream cross-compile it on x86_64. With recent upstream improvements, we can now build .NET Core for aarch64 on aarch64.
In the spirit of being First on Fedora, we want to make .NET Core available for aarch64 on Fedora.
Feedback
We don't have any feedback at this time from the community.
Upstream is enthusiastic and supportive of us enabling this in Fedora.
Benefit to Fedora
This change improves the coverage of Fedora packages on aarch64. .NET Core was previously only available on x86_64; it's now available on aarch64 as well. Users who are using Fedora on aarch64 can now use the normal distribution packages for .NET Core, instead of having to find, download an installing .NET Core some other way. As a result of this, Fedora becomes a more attractive target for developing and deploying applications on aarch64.
Scope
- Proposal owners:
- Will update .NET Core to bootstrap and build on aarch64 (along with x86_64). This shouldn't affect any other packages.
- Will work with package owners of packages that .NET Core depends on if those specific dependencies of .NET Core are broken, buggy or un-available on aarch64
- Other developers: N/A (not a System Wide Change)
- Release engineering: N/A (checked with #fedora-releng)
- Policies and guidelines: N/A (not a System Wide Change)
- Trademark approval: N/A (not needed for this Change)
Upgrade/compatibility impact
N/A (not a System Wide Change)
There is no known impact on upgrades.
.NET Core was just not available Fedora for aarch64 in previous releases of Fedora. It will be available in Fedora starting Fedora 33.
.NET Core is not a dependency of any other package, so users running Fedora on aarch64 and then upgrading from Fedora 32 to 33 will not automatically pull it in. They will have to install it manually.
How To Test
- Install Fedora 33 on aarch64
- Install .NET Core:
sudo dnf install dotnet-sdk-3.1 - Run .NET Core:
dotnet --info
The above steps should install .NET Core and show the .NET Core SDK and Runtime version numbers. There should be no error messages or any other failures.
User Experience
- Users using Fedora on aarch64 as a platform for .NET Core development will be able to use the Fedora-provided packages for .NET Core
