Now that we have our two projects in the same solution, expand the console application in the solution explorer, right click on the Dependencies node, and click Add Reference. Reference the Class Library from the Console Application For the rest of this series, I will refer to this as the domain logic library. I recommend ending the name of the library with Logic, Domain, or DomainLogic so that it's clear that this is a class library handling application logic. NET Standard class libraries.Ĭlick next and name the class library whatever you'd like, then create it. My general rule is that unless I have a compelling reason not to, I will always create. NET Framework 4.8 application of some sort, you would be unable to reference a. NET Standard is that it can be referenced from a. Make sure that the option has F# specified as the language and that you select the. In Visual Studio, right click on the solution at the top of your solution explorer and choose Add > New Project.įrom there, select the F# Class Library (.NET Standard) option as pictured below. Whatever name you choose, I recommend you include the name 'ConsoleApp' somewhere in the name to help remember that this is the console application as we will have multiple projects. ![]() Make sure that it lists F# as the language.Ĭlick Next, name the project whatever you'd like. In the new project wizard, change the Language Type drop down to F# and then look for the Console App (.NET Core) option as pictured below. Our solution will contain two projects initially, a. A console application that displays the current World and prompts the user for input, repeating the loop until the user hits X to exit.A World class that arranges the actors in the simulation.A Squirrel class that inherits from an Actor class.A WorldPos type that stores a 2D location in the game world.As the series progresses, we'll talk more about what we'll simulate and how it will work as well as what genetic algorithms are.įor now, we'll create a simple console application that generates a game board with a Squirrel somewhere on it, then displays the game board to the user and allows them to regenerate a new game board at random. The series will feature a 2D game board featuring a squirrel, a dog, an acorn, a tree, and a rabbit. This is part one of a multi-part series on building a genetic algorithm in F#. In this tutorial series, the end result is not going to be a console application, but for the purposes of focusing on the code at first, we'll start with a console application for simplicity. ![]() NET Core 3.0 console apps operate cross-platform and are not strongly tied to Windows like. They're typically used as part of automated processes or to integrate with other tools. NET conventions (though the syntax is sometimes very ugly to do so).Ĭonsole Applications are text-based utilities that run from the command line. This also means that you can mix functional programming and object-oriented programming based on the particular needs of what you're programming.į# is also not strictly limited to functional programming as F# can be used to create traditional classes following. NET, it compiles down to IL and runs as part of. Because you have fewer lines of code, it's harder for bugs to hide.īecause F# is part of. F# handles nulls better by default and concepts such as discriminated unions and pattern matching make it harder to make mistakes.Īdditionally, F#'s syntax is more concise than C#, meaning that it takes significantly fewer lines of code to express the same intent as it does in C# or other languages. The advantage of functional programming languages typically lies in application quality. Still, I want to share what I have learnedį# is a functional programming language that is part of the. This represents my best attempt to share the knowledge I have learned, but does not constitute an authoritative 'best practice' type of model and may include inaccuracies based on incomplete understanding. I've read a few books and written a neural net in F# as well as the code from this article series, but otherwise I am very new to the language. Important Disclaimer: The author is an F# novice.
