Introduction
We were all excited about the release of .NET 7, and as we know, every year around November, Microsoft releases the latest version of .NET. Microsoft made the .NET 7 release date on November 8, 2022, the opening day of the three-day .NET Conf online event. However, since then, Microsoft has continued to push forward, and .NET 7 has now officially reached end of life.
If you are still running on .NET 7, this blog will walk you through what it offered and what the latest version, .NET 10, brings to the table. 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.
.NET 7 Key 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),
- Improvements to Navigation
- Loading Progress Bar in Blazor web assembly
- Virtualization Improvements: put up things faster on screen and see a more responsive website
- Passing State
- Custom Elements Improvements
- Better performance for .NET Maui
12. Blazor Hybrid Authentication and Authorization: Previously, there was no support for building .NET Maui applications but now there is actual support present on How to do it which saves time.
13. Complex Authentication Support: Allow creating 8 complex tokens in the backend
14. Minimal APIs Improvements
- Output Caching
- Rate Limiting: Before you had to manually write the queue but now just rate limit your own application and then manage the rate of your call your dependencies and better user experience
- Upload Files in Minimal APIs
- Improvements to open API in minimal APIs
- Route Filter Handling
- Improved Dependency Injection
- Some Improvements in ASP.NET Core, like nullable models for MVC and Blazor Pages
15. Change the value of cookie consent from GDPR, in .NET 6 it was to be done manually but now just copy and paste a 20-line code and you get the cookie banner and acceptance and others.
16. Use both the gRPC and REST API simultaneously then you were required to code for both but now .JSON transcoding is added so if anybody calls your REST API and is unaware of how to use gRPC they can use REST making it fast for your service to service and client to service.
17. Other Additional Changes
- Loading Circle while loading the application
- Making the Good Code relatively Fast
- Basic Crypto Support for Blazor
This is the overview of everything you need to know about .NET 7 and to have more in-depth knowledge about the new and the previous versions you can refer to .NET Blog and .NET Conf and gain pertinent information and use the same.
What brought these many changes to .NET 7?
The .NET open-source community has communicated and presented plenty of inputs that help shape the .NET 7 release. Talking about the actual number of contributions there are more than 28k contributions made by over 8900 contributors from the community throughout the release of .NET 7.
Update: .NET 7 Has Reached End of Life, and .NET 10 Is Here
If you’ve been using .NET 7, here’s something important you should know as of May 14, 2024, Microsoft has officially ended support for .NET 7. That means no more security patches, no bug fixes, nothing. If your app is on .NET 7, it will still run, but just without a safety net.
The good news? Microsoft has just released .NET 10, and it’s a big upgrade.
Unlike .NET 7, which was a short-term release, .NET 10 is an LTS (Long-Term Support) version, meaning Microsoft will fully support it until November 2028. If you’re planning to move from an older .NET version, this is the version you should move to.
What has actually changed in .NET 10?
Here are the key areas where .NET 10 has significantly improved over .NET 7:
- Your apps run faster: Microsoft has made significant improvements that make applications perform noticeably faster and use less memory.
- Built-in AI support: .NET 10 includes native tools for building and integrating AI features, something that wasn’t available in .NET 7.
- Better security: Security standards in .NET 10 have been significantly upgraded, with better authentication and encryption updates for enhanced data protection.
- Improved developer experience: .NET 10 ships with C# 14, which introduces several language improvements that reduce repetitive code.
- Cloud Readiness: .NET 10 is built with cloud deployment in mind. Compared to .NET 7, apps are smaller in size, start up faster, and require less effort to configure on cloud platforms.

Frequently Asked Questions (FAQs)
Technically, .NET 7 can still be used, but since it reached end of life in May 2024, Microsoft no longer releases security patches or bug fixes for it. So, any issues discovered after that date will go unaddressed, which can prove risky.
Yes, you can migrate directly from .NET 7 to .NET 10 without going through intermediate versions. In fact, since .NET 10 is an LTS release, it makes more sense to migrate directly rather than upgrading in steps.
