Tech Stack

• .NET 8 (net8.0-windows)
• WPF (standard controls)
• NSec.Cryptography (Ed25519 signing)

Prerequisites

For development:

• Windows machine
• .NET 8 SDK
• Visual Studio 2022 or VS Code

For end users of the standalone executable:

• Windows x64
• No .NET installation required when using the self-contained build

Run From Source

From the repository root:

dotnet restore
dotnet build OrderlyAPI2.0/OrderlyAPI2.0.csproj
dotnet run --project OrderlyAPI2.0/OrderlyAPI2.0.csproj

Build Standalone Executable

Quick build:

.\build-standalone.ps1

Or with batch script:

build-standalone.bat

Manual publish command:

dotnet publish OrderlyAPI2.0/OrderlyAPI2.0.csproj -c Release -r win-x64 --self-contained true -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true -p:EnableCompressionInSingleFile=true -o ./publish

Expected output:

• publish/OrderlyAPI.exe

Credentials Storage

Credentials are stored in a local text file next to the executable:

• credentials.txt

Current format uses Base64 encoding for basic obfuscation. It is not strong encryption.

Repository Layout

• OrderlyAPI2.0/ - WPF application source
• build-standalone.bat - standalone build (CMD)
• build-standalone.ps1 - standalone build (PowerShell)
• create-distribution.bat - creates distribution package artifacts
• BUILD-GUIDE.md - detailed build/deployment guide
• STANDALONE-BUILD-SUMMARY.md - standalone build summary
• MIGRATION-TO-TEXTFILE.md - credential storage migration notes
• CREDENTIALS-LOCATION-CHANGE.md - credentials path change details
• WPF-UI-REMOVAL.md - UI dependency removal notes

Notes

• The project solution file is OrderlyAPI2.0.sln.
• Target runtime for standalone publish is currently Windows x64 (win-x64).
