Microsoft does not stop! For months now we have seen updates and news from the .NET development team and they have just released the third preview of .NET 7. This final version is planned for release in November this year, but until then let’s talk about the new features and performance improvements it will bring!

.NET 7 also intends to improve the developer experience by creating secure authentication and authorization that is easier to configure. This method enhances the application startup and execution of runtime.

The .NET 7 Preview 3 has many things to offer like enhancements to observability, codegen, native AOT compilation, GC regions, startup times, and many more. Well, you can also download .NET 7 Preview 3 from its official website for macOS, Windows, and Linux.

Now, let’s understand some .NET 7 new features and its latest updates in this release.

Native AOT for Lighter and Faster Apps

In the previous versions of .NET, AOT was in the experimental zone. But with the resale of .NET 7, AOT has become an official functionality in the DotNET or runtime repo.

AOT is referred to as Ahead-of-Time. AOT compilation is considered a pool of technologies that create code during application build time but not at run-time. However, if you are a .NET developer, you should know that AOT is not a new concept.

ReadyToRun is now available for clients and server scenarios, and Mono AOT for WASM and mobile. Native AOT offers full native pre-compilation to .NET desktop server and client cases.

In fact, the Native AOT is the same as existing AOT technologies of .NET. However, it only offers native artifacts. Since everything in the Native AOT is platform-specific, the Native AOT runtime cannot read .NET assembly file formats. The underlying operating system handles the processing of executable file formats completely.

The key advantages of Native AOT are its faster startup time, lower memory usage, restricted platform access (no JIT allowed), and reduced disk size. Applications begin to operate as soon as the operating system loads them into memory. The data structures are designed to run AOT-generated code rather than compiling new code at runtime. Well, other languages like Go, Swift, and Rust compile in a similar way. Native AOT is best suited when startup speed is important.

Make Your Apps Native AOT Ready

Native AOT enables app developers and library authors to leverage the advantages by ensuring that their apps can be trimmed easily. As we know, trimming is an essential method for Native AOT compilation. Hence, it will help your apps get ready for Native AOT.

Crossgen tool is one type of app included in .NET 7 when compiled with Native AOT. Crossgen is a CoreCLR AOT compiler and part of the .NET SDK. It generates ReadyToRun executables.

Because Native AOT is a short-lived process, the startup overhead reduces the overall execution time. Therefore, Crossgen can benefit from:

Compile CoreLib4182 ms3512 ms
Compile HelloWorld185 ms49 ms
ReadyToRun34.8 MB
NativeAOT17.6 MB

In the future releases of .NET, native AOT compatibility will be improved, but there will always be reasons to favor JIT in many circumstances.

GC Regions

Region’s functionality has been activated by default in .NET Preview 3, which should aid with memory utilization for high throughput apps. Regions are available for every platform except macOS and NativeAOT.

Cryptography: Parsing X.500 Names

This update makes working with certificates easier by introducing a class that clarifies the parsing of X.500 names. The CertificateRequest functionality considers an X500DistingishedName type as input for the certificate request subject in many of its constructor arguments.

Allow me to give you an example with the code here.

request = new CertificateRequest($"CN={subjectName},OU=Test,O=""Fabrikam, Inc.""", ...);

This is usually fine, except when subjectName contains a comma, a quote, or anything else that affects the parser. The X500DistinguishedNameBuilder class was created to remedy this issue.

There is no ambiguity in parsing because each method only works with a single relative differentiated name (RDN). You no longer have to guess what “CN” stands for (“Common Name”) because the RDN identifiers have been increased.

X500DistinguishedNameBuilder nameBuilder = new();
nameBuilder.AddOrganizationName("Fabrikam, Inc.");

request = new CertificateRequest(nameBuilder.Build(), ...);

Other amazing features that set .NET 7 apart:


Comprehensive documentation and increased integration with cloud services such as Azure App Services and Azure Container Apps will result from additional investments in the .NET cross-platform framework for creating distributed apps.

Enhanced Performance

It enhances the application startup and runtime execution performance.

Simplified Configuration

It makes configuration easier, ensuring secure authorization and authentication.

Cloud-Native Architecture

The major goal is to enhance the scale in large applications by developing self-contained systems (microservices) that can be installed and scaled independently while minimizing long-term expenses. Microservices architecture is adaptable and built to evolve in a way that monolithic architecture cannot.

Better Containers

Microsoft wants to improve telemetry to enhance container observability and make container images robust, secure, smaller, and faster. It is preferred for many enterprises to deploy cloud-native apps and microservices.

Enhanced .NET Upgraded Assistant

.NET Upgrade Assistant now comes in a better way. It is used to assist developers in upgrading their application portfolio with confidence and efficiency. The update will include more analyzers, code fixers, and support for more app types.

.NET Multi-Platform App UI (.NET Maui)

.NET Maui is the future of cross-platform native UI with .NET, and it’s a big element of .NET 7. It will improve internal development loop performance, support the latest .NET SDK tooling, enable faster app performance, and share more code when it ships for .NET 7.

Looking Forward with ASP.NET Core 7 Hosting Provider!

1. ASPHostPortal – Best Value ASP.NET Core 7 Hosting

Windows hosting has a reputation for being costly, but ASPHostPortal shared ASP.NET Core 7 hosting range shows it doesn’t have to be that way.

Final Conclusion – Upgrade Your Projects to .NET 7

.NET came into existence with the internet revolution in which distributed systems communicated over the internet. It was at the forefront of innovation, with many languages, one runtime, and a base set of libraries and APIs that were all integrated. However, like everything else in technology, .NET has also had to evolve.

On the 20th anniversary of .NET, Microsoft is changing the playing field after years of resisting open-source with .NET 7. Microsoft puts the .NET community at the center of everything they do, and they actively welcome fresh ideas and code contributions. The goal is to make the .NET ecosystem the platform of choice for developers all around the world.

The new functionalities and features of the platform iteration are open sources and cross-platform, putting Microsoft in a good position for the future. The general release of .NET 7 is scheduled for November 2022, and based on the previews, it appears to be a big success.

All three of these ASP.NET Core 7 hosting companies offer you a 99.9% uptime guarantee, so functionally, there isn’t a lot of difference between them.

My bottom line recommendation is to examine carefully the independent reviews for each company you’re considering. Then select the ASP.NET Core 7 hosting provider with the best overall reviews and customer support.
