Introduction
We are all excited about the release of .NET 7, and as we know, every year around November, Microsoft releases the latest version of .NET. The last version, .NET 6, was released on November 8, 2021, and following the same timeline, Microsoft made the .NET 7 release date on November 8, 2022, the opening day of the three-day .NET Conf online event which is the same as the previous year’s launch date .NET 6. The great news in this year’s new version is that it focuses primarily on being unified, modern, simple, and fast. So, without much ado, let us jump to the specifics.
What’s New in .NET 7 Features and Updates
Microsoft has introduced .NET version 7 with an STS (standard-term support) or the shorter supported version providing only 18 months of support. Microsoft introduced the STS version this year because it already mentioned in 2019 that it would release a new version of .NET every year around November. But, considering the new official .NET 7 features and updates, it still brings a significant number of changes and .NET 7 performance improvements for the Users. Given below are 17 noteworthy differences between .NET 7 vs .NET 6 are as follows:
1. On-stack replacement (OSR) that allows changing the executed code by a way in the middle of its execution. This will help the long-running methods to shift to a faster version in the middle of the execution.
2. Regex Improvements: Some regular expression improvements which make them a bit better in .NET 7.
3. Simplified LINQ Ordering
4. Dynamic PGO Improvements: The Dynamic PGO, is designed to make some key changes from the Static PGO which requires developers to use special tools separately from training, Dynamic PGO doesn’t require any of that; all you need to do is run the application you are interested in optimizing and then collect data for Microsoft!
5. Reflection Improvements: With this update by Microsoft, now in .NET 7 the overhead when invoking a member using reflection has been reduced considerably.
6. Application Trimming Improvements: Trim stuff that you don’t need in your specific application and make a smaller application thereby giving a smaller .exe size.
7. Trimming Libraries: Trim libraries that you don’t need or are not necessary for you.
8. Nanoseconds and Microseconds values in Date Time allow you more specific values from the Date Time object.
9. Memory Caching Improvements which is specifically in ASP.NET but this is an improvement in How we do memory caching.
10. TAR File Creation: .NET 6 already allowed .ZIP file creation but the latest version .NET 7 now allows creating .TAR file.
11. Blazor Changes: Blank Templates, Sample Blazor Template (with no sample data started in it),
