Common Pitfalls Implementing ASP.NET Core Apps

All you developers are familiar with the ASP.NET framework. It is basically an open source framework which helps developers to make cloud-based internet connected apps. Most of the web apps, IoT apps as well as mobile backends are developed through the help of an ASP.NET framework. It had first come out fifteen years ago as one part of the .NET framework. Builders have used this to make a great deal of such applications.

What is ASP.NET core?

The core is basically an upgrade on the previous framework. A great number of structural changes have been done on the new updated framework. This has been built to help optimize the application, allowing developers more flexibility when building their programs. The apps build here can run on any system, be it Windows, Mac or Linux. With the upgrade, you can include only the NuGet packages that you require. It decreases cost and increases performance. The new version is friendlier towards the builder, supporting side by side app versioning. It is lightweight and also the environment is cloud ready. Furthermore, it is open source. You can even self-host your apps and the new tools help your web designing.

However, there are certain pitfalls when implementing these apps:

Dependency:

Leaving IIS has plunged developers into dependency. So you have to download NuGet packages from the net which helps run it. The app has become self-contained so it is a bunch of NuGet packages which you have to plug and play. It does help it to make a cross-platform, flexible and simpler as you don’t have to install modules on your server. However, uploading each dependency is a strenuous process. Even tooling has packages that need to be uploaded. Difficult to get this framework into the server.

Deployment automation:

The set of tools for deployment is totally different now. Pipelines are the scripts that run in automation. These scripts should be reusable so that deployments are consistent. But in this upgrade, you have to create new scripts and your previous automation become useless.

The best way to get through this is to check what can be reused. Look at the deployment requirements prior to using the updated framework. Both IIS and windows will require all new modules for ASP.NET core framework apps to work. So when you first run it try to sort out most of the issues following windows guides before your server starts again.

Managed and unmanaged code:

A problem that occurs while using the new update is that during deployment using the old code kept giving an error. The older version used to run on managed code while this new version is a completely top framework. It is decoupled from your standard framework and will not run on the classic code.

Therefore you have to edit the application pool setting and switch it to unmanaged code for it to function. This is because of the cross-platform feature, disengaging it from IIS. It now uses the HTTP module.

Undoubtedly this framework is better for developers. It is slick and effective. It is advisable you read the guides about the platform to avoid pitfalls.
