SLNX, the new solution format in .NET ✨

Introduction

With .NET 8, Microsoft introduced a new solution file format: .slnx. This format aims to improve solution management, making large-scale editing scenarios easier and optimizing performance for large codebases.
As mentionned earlier in March in Chet Husk’s post on .NET blog, Microsoft now officially supports it in their latest SDK ! 😎
Before .NET 9, the only way available to use this new format was to use the “Save As” feature on an existing .SLN file and target the SLNX format.
Now new projects can be created by default using this format, which is pretty cool 🥳
