CSharpEssentials is a collection of NuGet packages that provide a range of helpers and utilities for .NET development. This library includes various packages designed to simplify tasks such as HTTP operations, background job scheduling, logging, and more.
Package Index
Below is a table listing all the current packages available in the CSharpEssentials library:
Package Name Description NuGet Link CSharpEssentials.HttpHelper Provides helper methods and extensions for simplified HTTP client operations. NuGet CSharpEssentials.HangFireHelper (#csharpessentialshangfirehelper)Contains utilities and extensions for integrating Hangfire background job processing. NuGet CSharpEssentials.LoggerHelper (#csharpessentialsloggerhelper)Offers logging helpers to trace requests using various Serilog sinks and logging strategies. NuGet ... ... (more packages coming soon) ...
Overview
The CSharpEssentials library is designed to be modular, offering dedicated packages for distinct aspects of .NET development:
HttpHelper: Simplifies HTTP client usage with additional resiliency features.HangFireHelper: Streamlines the integration and management of background jobs using Hangfire.LoggerHelper: Enhances logging capabilities by leveraging various logging sinks (e.g., Serilog).
Each package is intended to be used independently or in combination, depending on your project's needs.
Getting Started To install any of the packages, use the NuGet Package Manager or the .NET CLI. For example, to install the HttpHelper package:
dotnet add package CSharpEssentials.HttpHelper --version 1.2.2
CSharpEssentials.HttpHelper is a NuGet package that extends HttpClient functionalities by integrating resiliency and rate limiting strategies.
With this package, HTTP calls in your .NET applications become more robust, handling transient errors and request limitations gracefully.
Features
Resiliency: Implements retry and fallback policies to manage transient errors.Rate Limiting: Controls the frequency of HTTP requests to prevent overloads and adhere to API limits.Logging: Leverages CSharpEssentials.LoggerHelper to trace requests using various Serilog sinks.Custom Delegates: Utilizes a custom handler to attach multiple delegates during the HTTP call for additional processing and customization.Easy Integration: Seamlessly integrates with ASP.NET Core applications.Tested & Validated: Verified using both an ASP.NET Core controller and .http file examples.
Installation Install the package via the NuGet Package Manager:
dotnet add package CSharpEssentials.HttpHelper --version 1.2.2
