# .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: All models of generation 1 and Pi Zero are not supported because the .NET Core JIT depends on armv7 instructions not available on those versions.
## 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.
```
Exe
netcoreapp2.1
```
* If you get restore errors, make sure you have a nuget.config file next to your csproj that includes the dotnet-core myget feed: ``.
```
```
## Publishing an app to run on the Pi:
* Run `dotnet publish -r ` 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/netcoreapp2.1//publish` or `.\bin\Debug\netcoreapp2.1\\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. .NET Core depends on some packages from the Linux package manager as prerequisites to running your application.
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://docs.microsoft.com/en-us/windows/iot-core/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.**
