jorgef/fsharpworkshop

This system is an educational workshop for learning F\# programming, structured into four progressive modules covering types, functions, discriminated unions, and data binding. It provides a complete learning environment with application code, interactive scripts, and unit tests for each module. The project is built on .NET Core/Standard with modern SDK-style project files and cross-platform support.

A new F\# script file (Demo.fsx) was added to the Module2 directory. It demonstrates core language constructs including variable binding, function definition, tuple and record types, partial application, and function composition, serving as a practical example for users.

Module2 · high confidence

Added a new F\# script (Demo.fsx) to Module 3, providing code examples for basic variable assignment, tuples, records, function composition, and unit-of-measure conversions.

Module3 · high confidence

New files were added to the Module 2 application directory, introducing the core domain types and business logic for the v3 version of the module. The \Types.fs\ file defines a \Customer\ record, while \Functions.fs\ implements logic to promote customers to VIP status based on purchase amounts and to calculate purchase totals. A \Try.fsx\ script was also added to demonstrate the usage of these functions.

Module2/Application · high confidence

Introduced the application layer for Module3, defining the Customer type and associated functions to handle customer upgrades. The new code includes logic to promote customers to VIP status based on purchase amounts, retrieve purchase data, and increase customer credit, providing a complete workflow for customer status management.

Module3/Application · high confidence

Introduced the complete source code for the Module4 application, including type definitions (Customer, PersonalDetails, Notifications), business logic functions (credit increase, VIP promotion, adult checks), a service layer, and a Try.fsx script for interactive exploration. The change also includes a Data.json file containing sample customer purchase data and a paket.references file for dependency management.

Module4/Application · high confidence

Introduced the foundational F\# code for Module 1, including the Types and Functions modules, a Try script for interactive exploration, a Demo script demonstrating basic F\# features like tuples and records, and a Tests file with placeholder unit tests for customer promotion and purchase logic.

Module1 · high confidence

The Completed directory now contains the full, finished source code for all four workshop modules. Module 1 introduces basic F\# types, functions, and tests. Module 2 adds higher-order functions and function composition. Module 3 introduces discriminated unions, pattern matching, and unit-of-measure types. Module 4 adds JSON data binding with FSharp.Data, a console application entry point, and a service layer. Each module includes application code, interactive Try scripts, demo scripts, and unit tests.

Completed · high confidence

A change to existing behaviour in .ionide — 1 commit, 1 file.

.ionide · low confidence · unverified

Added new F\# demo scripts (Demo.fsx) in Module4, including examples for basic types, function composition, unit of measure conversions, list filtering, and object-oriented programming. The file also includes a JSON provider example using FSharp.Data. A fix was applied to the type provider path for demo.fsx and try.fsx.

Module4 · medium confidence

The workshop is now organized into four distinct modules covering bindings, functions, high-order functions, options, and type providers, each with corresponding application and test projects. The setup has been updated to require .NET Core SDK, Visual Studio Code with the Ionide extension, and Mono for Mac/Linux users. The README has been expanded to include detailed module descriptions, pre-requisites, and feedback from past attendees.

(repo-wide) · high confidence

Added unit tests for Module 4; Added unit tests for customer credit and upgrade logic.

The project files for the completed and module directories have been converted to the modern .NET SDK-style format. This migration standardizes the build system, enabling simpler project configurations and cross-platform compatibility. Specifically, application projects now target .NET Standard 2.0, while test projects target .NET Core 3.0 and reference testing libraries such as xUnit, Microsoft.NET.Test.Sdk, and Unquote.
