How to build the project using Mono?<\/strong><\/h2>\n
To verify that everything is working well. We will build a project \u2018testprogram\u2019 that will print output \u2018How to install mono on Ubuntu\u2019.<\/p>\n
Create a text file in any text editor and paste the below-mentioned source code in it:<\/p>\n
using System;<\/p>\n
public class testprogram\r\n\r\n{\r\n\r\n\u00a0\u00a0\u00a0\u00a0public static void Main(string[] args)\r\n\r\n\u00a0\u00a0\u00a0\u00a0{\r\n\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0Console.WriteLine (\"How to install mono on Ubuntu\");\r\n\r\n\u00a0\u00a0\u00a0\u00a0}\r\n\r\n}<\/pre>\n
Save the above file with the name \u2018testprogram.cs\u2019 in your system.<\/p>\n
<\/p>\n
Now, build the above source code by using the \u2018csc\u2019 compiler:<\/p>\n
$ csc testprogram.cs<\/pre>\n
<\/p>\n
The above command creates an executable file named \u2018testprogram.exe\u2019. You can now execute this file through the mono to display the output.<\/p>\n
$ mono testprogram.exe<\/pre>\n
The following result show display on the terminal screen after running the above\u00a0program:<\/p>\n
<\/p>\n
