Available for free, .NET Core is an open-source, cross-platform framework that can run ideally on Windows, Linux, and macOS and is specifically designed to help developers develop modern applications.
When considering switching from .NET Framework to .NET Core, you should assess the current application used in the business and determine whether it’s a good candidate for migration. If the chosen application uses the features supported by the .NET Core, it will be much easier to carry out the migration process.
However, if your web app doesn’t use the features supported by .NET Core, you must first make some code changes. Moreover, you can use various tools for .NET Development to automate the migration process.
The following are the steps involved in the migration process from .NET Framework to .NET Core:
Before starting the migration process, you should analyze the system background, codebase size, dependencies on specific Windows features, and third-party library compatibilities.
You can use Microsoft’s .NET Portability Analyzer to analyze the specific application’s dependencies and project references. In addition, with this tool, you can identify the APIs not available in the .NET Core.
The next step is to evaluate the existing .NET Framework used for web app development to identify if there are any compatibility issues, dependencies, or potential challenges for migration.
Once you have identified project dependencies and compatibility issues, it’s time to create a comprehensive plan outlining the approach, resources, and timeline required to migrate the .NET Framework to .NET Core.
In addition, don’t forget to outline the steps and potential risks involved in the migration process. It’s recommended to start with smaller components or modules and gradually switch to the entire application.
You can use various tools and resources to automate and smooth the migration process. As discussed above, the .NET Portability Analyzer by Microsoft can be used to assess the compatibility of the chosen application with .NET Core.
Moreover, consider leveraging the documentation and guides provided by Microsoft to gain valuable insights and guidance for a successful migration.
If .NET Core does not support your application features, you should modify the codebase to make the app compatible with .NET Core. Update or replace any dependencies or third-party libraries incompatible with the .NET Core.
Consider following some of these approaches to proceed with the migration:
It is the most crucial step, which involves migrating application settings, configuration files, and environment-specific configurations to the corresponding .NET Core equivalents.
Follow these steps to migrate from ASP.Net to .Net Core:
Create a new ASP.NET project utilizing the type suiting your project, such as ASP.NET Core Web API, ASP.NET Core Empty, or ASP.NET Core Web App. Your target framework must be .NET 5.
If your chosen application incorporates a database, you should migrate the data to the new project. You can leverage Visual Studio’s ‘Export’ and ‘Import’ features to transfer data seamlessly. Alternatively, you can use the Generate Scripts feature to create an SQL script and transfer existing data.
The migration process doesn’t end with transferring application settings, configuration files, and environment-specific configurations to the .NET Core equivalents.
Instead, it’s a must to thoroughly test the migrated application for any issues or bugs that might have emerged during the migration process. So, you should conduct thorough testing and quality assurance to spot and fix compatibility or performance issues.
After deploying the migrated application to the targeted environment, you should monitor its performance to ensure it functions optimally in the new .NET Core application development framework.
If you wonder why you should migrate from classic .NET to modern .NET Core, go through the following points:
