# Using a Raspberry Pi 400 with its 32-bit OS
|
||
|
|
|
||
|
|
## Easy As Pi
|
||
|
|
[Raspberry Pi 400](https://www.raspberrypi.org/blog/raspberry-pi-400-the-70-desktop-pc/) was launched on 2 November 2020. The Raspi has been around for ages but this is the first time its been embedded in a keyboard. A desktop PC capable of learning C# and .NET on for $70? Yes, please!
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Since I like life to be as easy as possible, I ordered the $99 model with all the useful extras like power adapter, mouse, and HDMI cable. All I needed to add was a monitor so I also bought a cheap Lenovo LCD.
|
||
|
|
|
||
|
|
## About the OS
|
||
|
|
Raspberry Pi OS is the official supported operating system but it is 32-bit even though the CPU is a quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.8GHz and 4GB of RAM.
|
||
|
|
|
||
|
|
In a separate article I explain how to set up [Ubuntu Desktop 64](../raspberry-pi-ubuntu64/README.md) if you want to use that instead.
|
||
|
|
|
||
|
|
## Setting it up
|
||
|
|
After connecting everything, Raspberry Pi OS starts and walks you through setting up language choices and so on. If you need help, the Pi website has good [instructions](https://projects.raspberrypi.org/en/projects/raspberry-pi-setting-up/4).
|
||
|
|
|
||
|
|
## Installing Microsoft Visual Studio Code
|
||
|
|
1. Start the Chromium browser.
|
||
|
|
2. Navigate to https://code.visualstudio.com/download
|
||
|
|
3. Raspberry Pi OS is based on Debian and is 32-bit, so underneath the main icons for Linux, in the **.deb** row, click the **ARM** button, as shown in the following screenshot:
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
4. Run the downloaded file.
|
||
|
|
|
||
|
|
## Coding with Visual Studio Code
|
||
|
|
|
||
|
|
1. From the desktop, click the Raspberry icon in the top-left corner.
|
||
|
|
2. Navigate to **Accessories** | **Visual Studio Code**.
|
||
|
|
|
||
|
|
If you follow the instructions in my book then you will create a folder named Code in your working folder and then create subfolders for each chapter.
|
||
|
|
|
||
|
|
You can see operating system and .NET information by entering the `dotnet --info` command in Terminal, as shown in the following screenshot:
|
||

|
||
|
|
|
||
|
|
## Limitations
|
||
|
|
Currently the C# extension cannot provide IntelliSense as you type. This is because it uses the OmniSharp language service and that is not (yet) compatible with ARM.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
This means that as you type code, you won't get any help with suggestions. But *real* programmers don't need IntelliSense, right? ;-)
|
||
|
|
|
||
|
|
Sadly, you also won't be able to use debugging tools or get help from the MSBuild project extension either, as shown in the following screenshot:
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
I will update this section as support is added.
