Top 10 reasons to migrate from .NET Framework to .NET Core

Some systems are difficult to replace, especially those that handle vital processes. But legacy technology can seriously harm your organization - higher costs, a small talent pool, and limited innovation are just a few of the downsides. Today, the .NET Framework is one of those legacy technologies, and moving to .NET Core seems like the best option.

As defined by Gartner, a legacy system is “an information system that may be based on outdated technologies, but is critical to day-to-day operations.”

Most companies choose to keep legacy systems because they contain historical information stored on them and the very idea of ​​updating them is perceived as an unnecessary investment of time and money. Yes, some systems are difficult to replace, especially those that handle vital business processes, but the truth is that legacy technology can have a damaging impact. That impact can range from customer perception to actual security threat to your organization. Today,  the .NET Framework, unfortunately, is now one of those legacy technologies.

But what does it mean for your business? How does it impact your daily operations?

Higher Costs:

Starting in November 2021, major Microsoft provided components used in web applications, such as ASP.NET MVC or Web API, will be retired. No bug fixing will be made available and effort towards security patches will start to phase out. For third-party components, the cliff may be even more pronounced.

For instance, DevExpress ASP.NET controls has already started to phase out support for .NET Framework versions below 4.5.2 as of March, 2021.

You will likely face higher support costs from outdated platforms, especially if you use third-party components that could remove support even sooner.

Also, lack of innovation can affect your budget too, for example: .NET Core is cross-platform, so it is compatible with Windows, Linux and Mac operating systems. In those cases where you need to run legacy ASP.NET web applications, you will have the flexibility to choose a Linux server over a higher priced server like Windows.

Reduced Talent pool:

Today the talent pool for .NET Framework is bigger compared to the .NET Core’s, but that will change rapidly as most developers are more interested in working with new technologies than anything  scheduled for sunset.

In fact, most of the content posted on blogs and youtube channels is focused on .NET Core, making it the framework of choice for new development.

Limited innovation:

In April 2019, Microsoft released the latest version of the .NET Framework and announced that there will be no new updates to its features. While they offered to continue to support, this only means that bug fixes and security patches will be provided, but there will be no product innovation and no further efforts to make it compatible with new and emerging technologies.

Money, talent, and obsolescence are big concerns for companies today, and they can be made worse if the migration process from a legacy technology to a new one is delayed. Waiting too long will make the leap too big and will likely cause instability issues, which are only addressed in a timely manner when migrating between consecutive releases, as all attention is focused on it and results in relevant updates and fixes.

In addition, .NET Core contains tons of improvements in terms of performance, scalability, flexibility, security, and compatibility over the .NET Framework, but no pressure!

  • .NET Core is cross-platform
  • .NET Core is open source
  • .NET Core supports a wide range of application types
  • .NET Core enables maximum application performance
  • .NET Core was built with the cloud in mind.

Good news is that we have done this migration before and while there is no magic and some rewrites & reworks are needed based on the complexity of each business; it is doable and less difficult than it sounds. Well, at Azumo we make it that way.

Plus, the benefits are tremendous for your business! Isn't that what we all need to get these days?
