In .NET 9, we have the default enabled DATAS. However, .NET 9 is not a long-term support (LTS) version, so many people will upgrade to .NET 10 and then realize that they need to prepare for the new GC. The new GC in .NET 10 brings significant changes, including a new garbage collection algorithm and a new heap layout. This means that applications that were optimized for the previous GC may not work correctly in .NET 10. To prepare for the new GC, developers need to understand the changes and how they affect their applications. They need to analyze their application's memory usage and identify any potential issues. They also need to update their code to take advantage of the new features and optimize their application's performance. This may involve rewriting some code, updating dependencies, and testing the application thoroughly. By taking these steps, developers can ensure that their applications are ready for the new GC in .NET 10 and can take advantage of its improved performance and features.
