# .NET Core on Raspberry Pi
|
|
|
|
Arm32 builds are available as community supported builds for .NET Core 2.0.
|
|
**There is no SDK that runs on ARM32** but you can publish an application that will run on a Raspberry Pi.
|
|
|
|
These steps have been tested on a RPi 2 and RPi 3 with Linux and Windows.
|
|
|
|
Note: Pi Zero is not supported because the .NET Core JIT depends on armv7 instructions not available on Pi Zero.
|
|
|
|
## Creating an app:
|
|
|
|
* [Install .NET Core SDK](https://www.microsoft.com/net/core) into a supported developer configuration.
|
|
(Raspberry Pi itself is supported only as deployment target but there is an unsupported version of the SDK available as well.)
|
|
|
|
* From the terminal/commandline create a folder named `helloworld` and go into it.
|
|
* Run `dotnet new console`
|
|
* You can find a `helloworld.csproj` file is created under current directory.
|
|
|
|
```
|
|
<Project Sdk="Microsoft.NET.Sdk">
|
|
|
|
<PropertyGroup>
|
|
<OutputType>Exe</OutputType>
|
|
<TargetFramework>netcoreapp2.1</TargetFramework>
|
|
</PropertyGroup>
|
|
|
|
</Project>
|
|
```
|
|
|
|
* If you get restore errors, make sure you have a nuget.config file next to your csproj that includes the dotnet-core myget feed: `<add key="dotnet-core" value="https://dotnet.myget.org/F/dotnet-core/api/v3/index.json" />`.
|
|
|
|
```
|
|
<?xml version="1.0" encoding="utf-8"?>
|
|
<configuration>
|
|
<packageSources>
|
|
<add key="dotnet-core" value="https://dotnet.myget.org/F/dotnet-core/api/v3/index.json" />
|
|
</packageSources>
|
|
</configuration>
|
|
```
|
|
|
|
* Run `dotnet publish -r <runtime identifier>` for example `dotnet publish -r win-arm` to publish the application for windows and `dotnet publish -r linux-arm` for Linux running on Raspberry Pi.
|
|
|
|
* Under `./bin/Debug/netcoreapp2.0/<runtime identifier>/publish` or `.\bin\Debug\netcoreapp2.0\<runtime identifier>\publish` you will see the whole self contained app that you need to copy to your Raspberry Pi.
|
|
|
|
|
|
## Getting the app to run on the Pi.
|
|
|
|
### Linux
|
|
|
|
* Install [Linux](https://www.raspberrypi.org/downloads/) on your Pi.
|
|
|
|
* Install the [platform dependencies from your distro's package manager](https://github.com/dotnet/core/blob/master/Documentation/prereqs.md) for .NET Core.
|
|
|
|
For Raspbian [Debian 9 Jessie](https://docs.microsoft.com/en-us/dotnet/core/linux-prerequisites?tabs=netcore2x#install-net-core-for-debian-8-or-debian-9-64-bit) you need to do the following:
|
|
```
|
|
sudo apt-get update
|
|
sudo apt-get install curl libunwind8 gettext apt-transport-https
|
|
```
|
|
|
|
* Copy your app, i.e. whole `publish` directory mentioned above, to the Raspberry Pi and execute run `./helloworld` to see `Hello World!` from .NET Core running on your Pi! (make sure you `chmod 755 ./helloworld`)
|
|
|
|
### Win10 IoT Core
|
|
|
|
* Install [Windows 10 IoT Core](https://developer.microsoft.com/en-us/windows/iot/GetStarted) on your Pi.
|
|
|
|
* Copy your app, i.e. whole `publish` directory mentioned above, to the Raspberry Pi and execute run `helloworld.exe` to see `Hello World!` from .NET Core running on your Pi.
|
|
|
|
** It is important that you copy the `publish` directory contents displayed at the end of the publish operation and not from another location in the `bin` folder. **
