Installing .NET Core on Linux ARM64

The following intructions can be used to install .NET Core on Linux ARM64.

Pro tip: Check out .NET Core Docker files to determine the exact instructions for installing .NET Core builds, for example .NET Core 3.1 ARM32 SDK Dockerfile.

Installing .NET Core Globally

The following instructions install the latest .NET Core globally. It isn't required to do that, but it provides the best experience.

curl -SL -o dotnet.tar.gz https://dotnetcli.blob.core.windows.net/dotnet/Sdk/master/dotnet-sdk-latest-linux-arm64.tar.gz
sudo mkdir -p /usr/share/dotnet
sudo tar -zxf dotnet.tar.gz -C /usr/share/dotnet
sudo ln -s /usr/share/dotnet/dotnet /usr/bin/dotnet

• For ARM32, switch "arm64" to "arm" in the link above.
• For .NET Core 3.1, you can get the download link @ https://dotnet.microsoft.com/download/dotnet-core/3.1 (look for ARM binaries).

Dependencies

.NET Core has the following dependencies, on Ubuntu (other distros will vary):

• libc6
• libgcc1
• libgssapi-krb5-2
• libicu60
• liblttng-ust0
• libssl1.0.0
• libstdc++6
• zlib1g

Trying out .NET Core

The following steps can be used to try out .NET Core.

dotnet new console -o app
cd app
dotnet run

Other software

• Docker on Debian, including ARM
• Raspbian (ARM32)
• Debian on Raspberry Pi 3
• Fedora on Raspberry Pi 3
• Ubuntu on Raspberry Pi 3
• Ubuntu on Pine64

Hi, is there any script that works on Raspberry Pi 4?

I tried to run this on my brand new Pi 4 but it doesn't work.

Any help is welcome.

I can confirm. Doesn't compile or run on arm64

I got same "Exec format error" as scotdwg. What "other" ARM64-linux exists that binaries do not work on standard Raspbian?

Try install for 32bit
curl -SL -o dotnet.tar.gz https://download.visualstudio.microsoft.com/download/pr/8ddb8193-f88c-4c4b-82a3-39fcced27e91/b8e0b9bf4cf77dff09ff86cc1a73960b/dotnet-sdk-3.0.100-linux-arm.tar.gz

@edyesaro: thank you! Your solution works, but requires clarification: As I understood, Raspbian OS is 32-bit ONLY(!) and even for ARM64 devices like RaspberryPI 3 you still need to install 32-bit programs. :(

Have the same issue... Got myself a raspberry pi 4 with a, what I thought 64bit ARM. But the above 64 script does not work. Also dont understand why the 64 version does not work.

I will try the 32bit version and post the results later.

Yep... 32 bit version it is...

Oh and another thing... Downloading the "latest" version as stated above you will now get version 5.0+ which is not always what you want.

I have been able to successfully install a 64-bit Ubuntu 18.04 using the instructions here: https://jamesachambers.com/raspberry-pi-4-ubuntu-server-desktop-18-04-3-image-unofficial/. It's a bit painful because you have to use a raspbian image to update the firmware, but it works.

You can now get an official 64-bit Ubuntu 19.10 Preinstalled Server image for Raspberry Pi 4 from: https://ubuntu.com/download/iot/raspberry-pi . After installing Ubuntu 19.10, on my Pi 4, I was able to install dependencies, proceed to manually install the .NET Core 3.0 ARM64 binary and make/run Console app successfully. Prior to installing Ubuntu, I did use the 32-bit Raspbian image to update the Pi 4 firmware.

Here is the direct download link for the dotnet sdk version 3.0.100: https://download.visualstudio.microsoft.com/download/pr/cbc83a0e-895c-4959-99d9-21cd11596e64/b0e59c2ba2bd3ef0f592acbeae7ab27d/dotnet-sdk-3.0.100-linux-arm64.tar.gz. On a Pi3 running Ubuntu 19.10, I used wget to pull this file down and then followed all the other instructions on this page. Worked like a charm.

When I run this :

dotnet new console -o app
cd app
dotnet run

I get this…

freebox@drive:~$ dotnet new console -o app

  - The following frameworks were found:
      5.0.0-alpha.1.19564.1 at [/usr/share/dotnet/shared/Microsoft.NETCore.App]

You can resolve the problem by installing the specified framework and/or SDK.

The specified framework can be found at:
  - https://aka.ms/dotnet-core-applaunch?framework=Microsoft.NETCore.App&framework_version=3.1.0-preview1.19506.1&arch=arm64&rid=debian.10-arm64
freebox@drive:~/app$

What is that version 5 ? And why the created application targets version 3.1.0 as the Template project is shipped with that version 5 ???

Raspbian is a 32-bit OS (they are keeping it 32-bit because they don't wan't to have to respond to questions like "why doesn't the latest Raspbian work on my old Raspberry Pi 1.0").
Even if you install 64-bit Raspbian kernel, the userspace is still 32-bit, so no, 64-bit dotnet won't work there and this is not a problem of dotnet.

If you wish to test on 64-bits, then it is probably best to install Ubuntu.

Same issue here. Target framework set to netcoreapp3.0.. but dotnet --version returns 5.0.100-alpha1-016050

Funnily enough.. setting netcoreapp5.0 actually works. :)

I updated the gist to resolve a bunch of the issues raised. Thanks!

Followed the instructions and getting this when I run dotnet in my cross-compiler shell

dotnet

Thanks

Hi Senior developers

Looks like I fix my issue for some reason you have to use the export command please follow this website tutorial to find out how to install .netcore on armv71 [.netcore]()

Hi,

I need to run an exe file on an arm base device.

Can I do it with .NET core?

How can I do it after I download and install .NET core?

similar error on ubuntu 19 arm64...

the link to the .Net Core 3.1 ARM Dockerfile seems to be broken, it should be: https://github.com/dotnet/dotnet-docker/blob/master/src/sdk/3.1/bionic/arm32v7/Dockerfile

i'm running arm64 ubuntu, why don't the regular ubuntu instructions just work?

@richlander I did these steps

curl -SL -o dotnet.tar.gz https://dotnetcli.blob.core.windows.net/dotnet/Sdk/master/dotnet-sdk-latest-linux-arm64.tar.gz
sudo mkdir -p /usr/share/dotnet
sudo tar -zxf dotnet.tar.gz -C /usr/share/dotnet
sudo ln -s /usr/share/dotnet/dotnet /usr/bin/dotnet
dotnet --version
6.0.100-preview.3.21168.18

and dotnet --version reported 6.0.100-preview.3.21168.18. Is there a way to get the latest non-preview version 6.0.201?

Disregard, found the correct URL:

https://download.visualstudio.microsoft.com/download/pr/33c6e1e3-e81f-44e8-9de8-91934fba3c94/9105f95a9e37cda6bd0c33651be2b90a/dotnet-sdk-6.0.201-linux-arm64.tar.gz

Confused as to why dotnet-sdk-latest doesn't pull that though...

DO anyone know the supported .Net core version and how it can be installed on Raspberry pi 3 model B 64bit ARM running with Raspbian os 11?
I already installed .Net core 6.0, but CLI can not identify it when I run

dotnet

Can you open an issue at dotnet/sdk and CC me?
