Inhalt: F# is a functional-first programming language developed by Microsoft and used extensively in financial analysis and financial applications. F# expert developer Kit Eason steps you through the process of developing a simple F# financial application: a Twitter bot that charts stock price changes and respond to tweets with some simple descriptors of the stock performance, including gain/loss and highs/lows. Along the way, you'll learn the basics of F# syntax, including values, arrays, functions, and expressions, and how to test your code, analyze and chart third-party data. The lessons also provide a primer to concepts like test-driven development and railway-oriented programming-best practices for any F# development workflow. Umfang: 02:51:05.00
Inhalt: Automated testing is a popular topic in software development, but it's still often seen by developers as overhead rather than as an opportunity. By leveraging F# and some external tools and libraries, you can make automated testing easy, enjoyable, and productive. In this course, learn about a variety of techniques for writing automated testing code in F#. Kit Eason explains how to use xUnit-a .NET unit-testing package-to do some test-driven development, and demonstrates how to improve your test run experience using NCrunch, a test runner. He shows how to use FsCheck to generate test cases, and how to use Expecto to move into the world of tests as first-class values. He also covers the use of Canopy to automate the testing of web user interfaces, and of mocking to tame dependencies. Umfang: 02:33:03.00
Inhalt: Visual Studio 2017 marks an important point in the history of F# and Visual Studio. For the first time, open-source developers have made a major contribution both to the language and to the tools directly available in Visual Studio. In this course, get a quick-yet thorough-tour of the new features and tools available in Visual Studio 2017 and F# 4.1. Kit Eason discusses the new value types that provide an opportunity for performance gains, the new result type which gives you access to the railway oriented programming style of error handling, and program organization and readability changes. Plus, he explores the evolution of tooling for F#, and explains how F# tooling has changed in Visual Studio 2017. To wrap up the course, he shares how you can contribute to the F# language and tooling by getting involved in the open-source community. Umfang: 01:14:13.00
