The web and mobile app development sector is thriving, and the digital populace is growing alongside it. We’ve witnessed a flurry in the industry, with increased competition among developers and entrepreneurs.

Every company wants to be ahead of the competition, and the key to doing so is to identify a technology that meets your customers’ needs. Therefore, using the best Asp.NET core Libraries is crucial if you are working in DotNet. Now let’s check what is DotNET.

What exactly is DotNet Core?

It is a cross-platform and lightweight DotNet framework for developing commercial applications and services. Net core is a combination of the following components: GC, Runtime, AOT, Base Class Library, JIT, ASP.NET, ML.NET, C#, F#, WPF, WinForms, Entity Frameworks, and Xamarin.

Microsoft met the criteria 18 years ago and has since provided user-friendly and customer-centric services. Microsoft’s .NET framework has been a boon, and the even newer.NET Core is the most significant and useful upgrade of the framework, providing dynamic, powerful, and feature-rich websites, mobile apps, and web-based programs.

It is advisable to use the best Asp.NET Core Admin Template to build a responsive web app.

When an entrepreneur wants to create a powerful, highly functional, and safe web application, the.NET framework is their first choice. Despite the fact that it has been nearly 20 years since Microsoft first introduced this framework, the DotNet framework continues to provide value.

The dotNET core framework has grown at an unanticipated rate in the last few years. Besides, with the fame, .NET core gained one rank over the previous year, and statistics reveal that developers would prefer .NET core libraries more than they did last year. Based on the reputation and popularity of the.net core framework, the framework was listed as the first pillar in the Hall of Fame in 2018.

Now, let’s head toward the list of the best Asp.NET core Libraries.

The Best DotNET Libraries To Use

Well, libraries as you know help to boost the workflow by providing the essential components. Therefore, while working with Asp.NET Core you will need the best DotNET Libraries. To help you with it, we have curated this list of the best DotNet core libraries. For inspiration, you can check the .NET Open Source Projects.

What is a DotNET Library?

.NET library also known as .NET framework class library is a collection of reusable types, interfaces, and namespaces that developers can use to create web applications, desktop applications, and mobile applications.

What are the advantages of using .NET libraries?

– Wide range of functionalities
– Consistency
– Improved productivity
– Cross-platform support, and many more…

Now, let’s start the list of Asp.NET core Libraries.


DotNET Libraries

One of the best DotNet libraries to use. Polly is a.NET resilience and transient-fault-handling library that enables programmers to fluently and safely define policies like Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback. Besides, Polly targets.NET Standard 1.1 and 2.0+ as of version 6.0.1.

In addition, Polly can safeguard your resources, stop you from sending requests to broken services, retry failed requests, cache earlier results, terminate lengthy queries, and, when all else fails, return a default value with only a few lines of code. Additionally, it supports sync and Async calls and is thread-safe.

Besides, this DotNet core library also provides two circuit breaker implementations: the Basic Circuit Breaker, which trips after a predetermined number of faults that happen consecutively, and the Advanced Circuit Breaker, which trips after a predetermined number of faults that happen within a specific time frame during which a sufficient number of requests were made.


  • Wait & Retry Policy
  • Circuit breakers
  • Policy Wraps
  • Timeout
  • Bulkhead Isolation policy and much more



The next one on the list of the best DotNet Libraries is Automapper. Well, mapping code is boring, and testing mapping code is even more boring. That’s where Automapper comes to the rescue. AutoMapper provides a simple configuration of types and simple testing of mappings. It converts an input object of one kind into an output object of another type, object-object mapping functions.

The interesting thing about AutoMapper is that it offers some intriguing conventions to remove the tedious task of figuring out how to map type A to type B. To map two types, essentially no setting is required as long as type B adheres to AutoMapper’s defined norm.

In an application, mapping can happen in a variety of locations, although it typically happens at the borders of levels, such as between the UI/Domain and Service/Domain layers. Object-object mapping creates separated models where issues for each layer can only affect types in that tier because concerns from one layer frequently conflict with those from another.


  • Custom Type Converters
  • Custom Value Resolvers
  • Conditional Mapping
  • Null Substitution
  • Value Converters
  • Value Transformers
  • Before and After Map Action and many more.

However, it will function on every platform ASP.NET Core supports and be compatible with anything that speaks HTTP.

Until it encounters a request builder middleware, it manipulates the HTTP Request object into a state indicated by its settings. There, an object called an HTTP Request Message is created and used to send a request to a service further down the line. The final step in the Ocelot pipeline is the middleware that submits the request. It doesn’t make a middleware call after that. The response from the downstream service is retrieved as the requests go back up the Ocelot pipeline.
