Migrating From ASP .NET To .NET Core

Introduction:

Code Migration from asp.net to .net core is essential to develop more secure applications and allows the improvement of the product performance and it solves the complex problems of customers and provides the best user experience with the help of the latest inbuilt templates and modern enhancements of .net core and interactive features. ASP .Net Core, a universally embraced using an open-source web framework, is comprehensive, and it enables ASP.NET MVC and ASP.NET Web API, including exceptional innovative features.

Code migration is also important to an improved platform that provides the assurance to leverage automated features in your applications.

Using ASP.NET development services advanced features, you can enhance your application with the help of its scalable, flexible, and best user interface capabilities with the help of .net 5 that is unified and has all the abilities in its framework. .Net applications are migrating to .Net Core to develop futuristic solutions. Here, in this assignment, we will understand all potential details and intelligence to migrate to .Net Core along with its business benefits, tricks for smoother migration, and ideas.

Classic ASP.NET operates on Windows only, which limits the possibilities of containerizing the services on another side. ASP.NET Core is much quicker

In certain scenarios, Classic ASP.NET is instantly end-of-life, as it doesn't help from automation and innovations and it stops you from utilizing other newer technologies (like Entity Framework Core or gRPC)

Here are the following features for migrating your application from ASP.Net to .Net Core

Cross-Platform Support
ASP.NET Core development allows cross-platform maintenance that can develop your applications into multi-platforms like Linux, Mac, and Windows platforms, and it can establish cloud and IoT-based applications with the help of modernized architecture. This capability did not exist in the previous versions of .Net versions.

Magnified Performance and Scalability
In the .Net Core framework, it contributes to more improved performance along with agility and adaptability features. It has advanced inbuilt microservice and containerization capabilities that allow .NET Core to accomplish and develop your applications with the help of various microservices and docker that provide scalability to your apps with the most competent execution, speed, and efficiency techniques.

Quick Development and Deployment
.Net core provides various features examples such as modular architecture, robust UI components, automatic updates, more extensive community help, reliable methods continuous integration including client-side frameworks, cloud-ready, lightweight using dependency injection. These methods perform improvement of more durable and allow more durable and fast continuous development and deployments to business.

Steps to Migrate

The following steps will accommodate you to migrate to .NET Core:

  • Retarget your projects and set the command to port to target .NET framework 4.7.2 or the latest versions. When .Net Core doesn’t recommend a particular API, for executing the specific APIs using Net Framework-specific, you can use the alternate API in your applications.
  • Next step, you can use the highlighted .Net Portability Analyzer. This tool examines assemblies and shows if these assemblies are portable or not.
Steps to Migrate
  • In this step, install the .NET API analyzer it enables the potential benefits of identifying compatibility issues and helps you to understand and recognize specific APIs that give the PlatformNotSupportedException on platforms it overcomes such issues.
platformnotsupportedexception
  • In this step, transfer each packages.config dependencies to the PackageReference inbuilt format using the transformation mechanisms packages.config.
  • In this step, .Net Core allows you a simplified project file format then .NET framework using it, we can create new projects with .net Core and can clone source files or transform our existent files.
  • In this last step, it’s expedient to port your test and verify your code: Porting is one so notable innovation that can create damage if it’s not defined well. It is extremely advised to port your test and verify the project and test and run the code.

Why porting to ASP.NET Core?

Why porting to ASP.NET Core?

ASP.Net Core MVC provides plenty of features that define the more interactive web development. using the Model-View-Controller template, model binding, model binding, Razor syntax, and validation. Below are the detailed levels of understanding of these features and best practices.

Cross-platform is the best example of distinctive features that make it more in demand. Using this feature, you can run your application in Windows and Linux environments.

Performance is another feature of developing a great performance application. ASP.NET Core manages 2.300% added requests per second as per the comparison from ASP.NET 4.6, and 800% more extra requests as per second than node.js.

Tag Helpers It is Server-part code and provides for creating and rendering HTML components in Razor files.

View components It is the latest tool, related to partial views, but provides the best more eminent performance compared to previous versions. DI using views. Here, most of the data presented in views comes from the controller action method.

Combined xproj & csproj files together

Here you can add two types of xproj & csproj projects files and can refer to each other at the same time, which is eventually what we concluded up doing for our Windows targeted builds of Prefix.

NetStandard vs NetCoreApp1.0

NetStandard is intended as a general standard so that .NET 4.5, Core, Xamarin, UWP for generating the shared library that will be a NuGet package, as per the NetStandard. If you are developing your application from scratch, you can use and target NetCoreApp1.0 as the framework and can deploy it to Macs or Linux or if you want to deploy on Windows, you can refer to .NET 4.5.1 or later.

HttpModules and HttpHandlers are followed by new “middleware”

Middleware has been composed of substitute modules and handlers. It is related to how Owin and different languages manage this kind of functionality. They are really simple to work with.

FileStream upgraded to System.IO.FileSystem

Here few basic classes that developers use daily basis as per their requirements have been pushed to various packages. As FileStream is no longer in the System.IO assembly package/reference. The developer can add the package using the System.IO.FileSystem.

Platform-specific code as per the Microsoft specific RSA

.NET Core is intended to operate on Windows, Macs, and Linux. In some scenarios, we see compilation issues when code runs on windows but fails on a Mac or Linux. Using .Net core, we can use RSACryptoServiceProvider class, which performs as reusable and overcomes the compatible platform exception "platform not supported” type exception". RSA provider API is based on Windows-specific using RSA.Create() which is a more universal implementation and has insignificantly various methods.

Newtonsoft converted to default to camel case on particular field names

In .Net core, Newtonsoft is switched to defaults to camelCase in C# programming. This will generate every class of REST APIs to develop your code using PascalCase.

ASP.Net core logging

Earlier versions of .Net developers used log4net library to generate the logs. Using .Net core, we have the upgrades in logging. For converting existing ASP.Net applications to .NET core. We need to just upgrade to the newest NuGet packages. In ASP.Net logging, we have three mechanisms:
Advanced Log4Net: It has its latest features and trends from logging frameworks.

NLog
NLog has instantly enhanced the next most modern framework for .NET logging with additional innovative features. NLog even operates transversely using Mono, Xamarin, and other runtimes. NLog is a protected using logging framework for ASP.NET Core.

Serilog
Serilog produced and develop more variables and objects using structure to logging . It supports all the common logging features using configurable output targets, and it's more advanced than log4net.

Web API is Gone and Part of MVC Now

Here, Web API and MVC merged and can be implemented using API-type applications. The new MVC 6 that crafts with ASP.NET Core merge the most beneficial of both MVC and Web API classes from ASP.NET. From any controller, you can perform a View, and MVC will perform serializing it and define the results. Various routing styles allow you to perform basic MVC web applications or more extended REST-style APIs using its interactive functionalities.

Modular architecture: Using ASP.NET Core we can use NuGet packages, it provides that allow the best optimization and can integrate various required dlls, packages references in the application,

This develops solution representation and decreases the time for the developers.

Code analysis: It provides how to determine how compatible your application solution is with the .NET Core framework.

Migration types: It determines how you can migrate your code based on what basis your application is developed and published. It Understands how and where each project is suitable in the migration approach and checks the complexity and volume of Windows distinct code.

Migration of the .csprojs files: it regenerates your project files to the necessary Microsoft.NET.Sdk format.

Code migration: It transforms your C# code to .NET Core/.NET as per the defined Standard rules.

Beneficial Suggestions For More continuous .NET To .NET Core Migration

  • Any framework movement will need continuous monitoring, pre-planning, network willingness, code security, and plans to fix issues if they originate
  • For more continuous migration,
  • We can start with the more inadequate modules/projects rather than moving a complete codebase solution to the .Net Core.
  • The dotnet try-convert tool supports regenerating your project solution to the .Net Core. You can use it as an origin point to automate essential information.
  • Classify the “base” of the library using data models or properties and methods that are required. Prepare and copy the base within a new .NET Core project. Perform any modifications required to assemble the code. Prepare and copy added layer of code and republish it.
  • Using the open-source code editor of NET Core developers can also utilize the Microsoft called Visual Studio (VS) code, which is recommended over all advanced OS systems such as macOS, Windows, Linux.
