LogicBuilder.App.Utils

Overview

LogicBuilder.App.Utils is part of the Logic Builder ecosystem and is a utility library that provides essential classes and helper methods used by business applications to perform routine operations. It maintains reusable functions which the logic builder workflow depends on.

Purpose

This library simplifies common business application tasks by providing:

• Reusable Components: Common functionality needed across business applications
• Parameter-to-Operator Conversion: Transforms UI-generated parameters from LogicBuilder.Forms.Parameters into operator classes
• LINQ Expression Generation: Leverages LogicBuilder.Expressions.Utils to build type-safe LINQ expressions
• Object Mapping: Uses AutoMapper for efficient object-to-object mapping during the transformation process

Features

• ✅ Targets .NET Standard 2.0 for broad compatibility
• ✅ Converts Logic Builder form parameters into executable operators
• ✅ Generates strongly-typed LINQ expressions for querying and filtering
• ✅ Built-in support for owned entity expansion via OwnedEntityAttribute
• ✅ Integrates seamlessly with the Logic Builder ecosystem

Installation

Install via NuGet Package Manager:

• dotnet add package LogicBuilder.App.Utils

Or via Package Manager Console:

• Install-Package LogicBuilder.App.Utils

HttpClientHelper

A simplified wrapper around HttpClient that provides strongly-typed HTTP operations with built-in JSON serialization/deserialization.

Key Benefits:
