Creating C# application’s on Raspberry Pi

Buy (and receive) : Raspberry Pi kit (Raspberry Pi 2, HDMI cable, Wi-Fi Adapter/LAN wire, USB charger/normal USB driver mobile charger, Memory Card with NOOBS preinstalled)… Done
You would have got NOOBS preinstalled…so OS is ready….Done
Connect Raspberry Pi to internet using your Wi-Fi Adapter.
- Open command prompt and type in
```
sudo iwlist wlan0 scan
```
  This will list all the Wi-Fi networks available. You would need to note the ESSID of the network you wish to connect.
- Open the “wpa_supplicant” file as below
```
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
```
  Go to the bottom of the file and type in
```
network={
ssid="The_ESSID_from_earlier"
psk="Your_wifi_password"
}
```
- Now save the file by pressing Ctrl+X then Y, then finally press Enter.
- Reboot your Pi :
```
 sudo reboot  
```
- You can verify if it has successfully connected using
```
 ifconfig wlan0  
```
  If the “inet addr” field has an address beside it, the Pi has connected to the network. If not, check your password and ESSID are correct.
Now to write C# applications we need to intall Mono on our Pi
```
$ sudo apt-get update
$ sudo apt-get install mono-runtime
```
To make your mono applications make a REST based calls we would need to install trusted roots certificate from Mozilla as below
```
$ sudo mozroots --import --ask-remove --machine
```
Now open Visual Studio and create any simple “Hello Word” Console Application. Build and generate the ‘.exe’ file.using System;
```
public class HelloWorld
{
static public void Main ()
{
Console.WriteLine ("Hello from Raspberry Pi");
}
}
```
Download FileZilla Client from: https://filezilla-project.org/ . This is used for transferring your files from your desktop to Raspberry Pi.
Once download and install click File -> Site Manager.
Host: Ip Address of Raspberry Pi ( use command ip addr to get the Ip from Rasp)
Protocol: SFTP
Logon Type: Normal
User: pi
Password: raspberryThen you will be able to transfer the file.
Once you have copied your Release folder into Raspberry Pi. I have create a folder called Code and dumped the Debug file. Our Rasp will look as below
In Raspberry Pi you will be able to run your application as ,
```
mono /home/pi/Code/Debug/Device.exe
```
