OVERVIEW:


F# is a functional programming language. To understand F# constructs, you need to read a couple of lines about the programming paradigm named Functional Programming.

Functional programming treats computer programs as mathematical functions. In functional programming, the focus would be on constants and functions, instead of variables and states. Because functions and constants are things that don’t change.

In functional programming, you will write modular programs, i.e., the programs would consist of functions that will take other functions as input.

Programs written in functional programming language tend to be concise.

About F#

Following are the basic information about F# −

  • It was developed in 2005 at Microsoft Research.

  • It is a part of Microsoft’s family of .Net language.

  • It is a functional programming language.

  • It is based on the functional programming language OCaml.

Features of F#

  • It is .Net implementation of OCaml.

  • It compiles .Net CLI (Common Language Interface) byte code or MSIL (Microsoft Intermediate Language) that runs on CLR (Common Language Runtime).

  • It provides type inference.

  • It provides rich pattern matching constructs.

  • It has interactive scripting and debugging capabilities.

  • It allows writing higher order functions.

  • It provides well developed object model.

Use of F#

F# is normally used in the following areas −

  • Making scientific model

  • Mathematical problem solving

  • Artificial intelligence research work

  • Financial modeling

  • Graphic design

  • CPU design

  • Compiler programming

  • Telecommunications

GET STARTED:


To choose a Region follow the below step:


1. Sign in to the AWS Management Console.


2. Choose a service to go to that service's console.


3. In the navigation bar, choose the name of the currently displayed Region. Then choose the Region to which you want to switch.


Step instructions for how to assess and monitor the health and proper function of the application:


1. Navigate to your Amazon EC2 console and verify that you're in the correct region.


2. Choose Instance and select your launched instance.


3. Select the server to display your metadata page and choose the Status checks tab at the bottom of the page to review if your status checks passed or failed.


To verify the installation, follow the below instructions


Step 1. Connect to SSH:


  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

  2. In the navigation pane, choose Instances.

  3. Select the instance and choose Connect.

  4. Choose SSH Client.

  5. Copy the SSH command and paste it into the terminal.

ssh ubuntu@publicIP -i [Path of key pair file]

If it shows an access denied message run the following command, then run the above command again to connect via ssh.


chmod 400 [Path of key pair file]

Once launched in the Amazon EC2 Service, please connect to the instance via an SSH client using the ec2-user with the key pair associated at launch. Once connected as the ec2-user user, you will be able to sudo to the root user


Step 2. Verify the installation:

Follow the steps to verify the fsharp installation

1. Login with ssh


2. Type the below command to check the version


3. To check the version :

fsharpc --version


How to use the fsharp in the terminal:


1. After connecting with ssh write the below command:

sudo nano helloworld.fs

2. Paste the following code into the file:

printfn "Hello, World!"

3. Then run the below command :

fsharpc helloworld.fs

4. Then run the below command

mono helloworld.exe

The output "Hello, World!" should appear in your terminal. That's it! You have successfully printed "Hello, World" using fshrap in the terminal.


4. After using the above command then verify written the below command mentioned below image:




To monitor and assess application functions:-


a. Navigate to your Amazon EC2 console and verify that you're in the correct region.


b. Choose Instances and select your launched instance.


c. Select the server to display your metadata page and choose the Status checks tab at the bottom of the page to review if your status checks passed or failed.
