#RaspberryPi – How to install #DotNetCore in a #RaspberryPi4 and test with #HelloWorld (of course!)

Hi!

During the next couple of months, I’ll be sharing some amazing experiences around AI. Some of these experiences includes IoT devices like a Raspberry Pi, and of course some Machine Learning.Net (ML.Net). Because ML.Net is built with .Net Core, it makes sense to share the 5 simple steps you need to do to install .Net Core in a Raspberry Pi.

Of course, my 1^st try was to navigate to the official .Net page (see references), which automatically detect my Linux distro and proposes a set of x64 SDKs.

I’m completely sure that I’m working in a 32 bits environment, however I’ll double check this with the following commands

sudo apt-get install lshw
lshw

After installing lshw I confirm that I’m in a 32 bit environment

Bonus: lshw is a small tool to extract detailed information on the hardware configuration of the machine. It can report exact memory configuration, firmware version, mainboard configuration, CPU version and speed, cache configuration, bus speed, etc. on DMI-capable x86 or IA-64 systems and on some PowerPC machines (PowerMac G4 is known to work).

Now I need to navigate to the download page to download the specific Linux 32-bit version (see references).

Once I got the image downloaded its time to extract the file on a specific folder. I’ve created a folder named “dotnet” with the following command

sudo mkdir -p dotnet

And to extract the image from the Downloads folder

sudo tar zxf dotnet-sdk-2.2.401-linux-arm.tar.gz -C
/home/pi/dotnet/

Let’s create a symbolic link to the extracted binaries

sudo ln -s /home/pi/dotnet/dotnet /usr/local/bin

And it’s done! Let’s invoke the .DotNet help command to test it

Now we can follow the steps of [.NET Core on Raspberry Pi, see references] to create a Console Application and to test the device.

To create a new console App

dotnet new console

And test the app

sudo dotnet run

We can publish the app for linux / raspberry pi

sudo dotnet publish -r linux-arm

And copy the generated folder to be used in another device

./bin/Debug/netcoreapp2.2/linux-arm/

So next steps will be some other tests with Raspberry Pi and .Net Core. And the following image is a big teaser of this

Happy coding!
