.NET 5 has reached the End of Life

In recent years, especially with the pandemic, everything has been moving very fast. The release of .NET 5 by Microsoft was only a year and a half ago (specifically on November 10, 2020) and we have to say goodbye to it.

Sadly, Microsoft’s deadline for developers to migrate to .NET 6 is ending and support for .NET 5 ends on May 10, 2022.

On the bright side, the new version of the Framework: .NET 6, will bring LTS (long-term support) and according to Microsoft, it will last until the end of 2024.

What will happen with .NET 5 projects?
One of the reasons why Microsoft is going to stop supporting .NET 5 (and other older versions) is because those versions must be signed with algorithms and currently they are signed with the SHA-1 algorithm. This algorithm has been vulnerable for some time and can affect from document signing to HTTPS certificates, to backup systems and Version Controls (git).

As a curious fact, although this happened a couple of years ago, Google managed to break this algorithm by managing to have 2 different PDF files with the same Hash.

At first, nothing will happen, but you will no longer receive security updates and support from Microsft. It is not the end of .NET 5 because this date simply refers to updates, patches, technical support, or security fixes but this could leave many applications exposed to new (and not so new) vulnerabilities.
That is why any developer who has projects in .NET 3.1 or .NET 5, should migrate them to .NET 6 in order to continue receiving all the updates and support from Microsoft.
