The heart of the Microsoft development experience has been the .NET Framework, which has changed significantly in the era of .NET Core and now the unified .NET 8 and the soon to be released .NET 9. Understanding these changes, along with the new features in C#, is crucial for success in the Microsoft development world. This track covers foundational topics such as code analysis, concurrent programming, design patterns, background tasks, and useful features in .NET/C#. Quick sessions on safer coding practices and upgrading applications, along with a hands-on lab and a workshop to enhance your C# skills, are also part of this track.
