Inside .NET Core 2.1: Enhanced Performance and Developer Experience

Recent updates to .NET Core 2.1 have introduced significant improvements in performance and developer productivity, making it a must-have update for any .NET developer. One of the standout features is the enhanced support for working with strings, which now feel more intuitive and efficient in scenarios where performance is critical.

About the ArrayASCIIString

In the .NET Core 2.1 release, the ArrayASCIIString type has been refined to provide better handling of ASCII-related operations. This new type is particularly useful for developers who frequently deal with text data and need to optimize their string manipulation tasks. Its efficient internal handling of characters, combined with a smaller memory footprint, makes it an excellent choice for high-performance applications.

NullReferenceException Prevention

The release also introduces improved mechanisms to prevent NullReferenceException errors, one of the most common yet avoidable issues in .NET development. The new system now provides more intuitive null checks and error messages, making it easier for developers to identify and address null issues in their code. This is a welcome addition, as it reduces the amount of time and effort required to debug issues that were once straightforward to encounter but frustratingly difficult to resolve.

Improved Support for NullableRef

Another key improvement in .NET Core 2.1 is the enhanced support for NullableRef, a feature that allows method parameters to be marked as nullable by default. This change simplifies nullable reference types and ensures better type safety in code. Developers can now enjoy smoother interaction with nullable types without having to manually annotate their code, leading to reduced cognitive load and improved code clarity.

Events and delegates have received similar attention to detail, with better documention and error handling in place to assist developers during event subscription and unsubscription processes. This has been a long-requested feature, and it’s great to see it FINALLY getting the attention it deserves.

Breaking changes and known issues

It’s important to note that this release also introduces a few breaking changes that developers need to be aware of. For instance, the removal of certain deprecated APIs and the adjustment of some default configuration settings. Whiledot this may require some adjustments to existing projects, the overall benefits of .NET Core 2.1 far outweigh these minor drawbacks. Most notably, the deprecated support for MMC Certificates has been removed, which may necessitate changes in how certain applications store and manage keys.

Complete overhaul of event handling systems

One of the most significant changes in .NET Core 2.1 is the complete overhaul of event handling systems. This new architecture provides developers with more control over event subscription and expiration times, as well as advanced mechanisms to prevent memory leaks in long-running applications. The new system also simplifies the implementation of custom event handlers, reducing the boilerplate code that was previously required.

Going beyond the obvious, the new release also introduces a subset of the JSON-Like object parsing functionality, allowing developers to work with $t typed objects in a more intuitive manner. While this feature is still in its early stages, it shows great promise for future releases and aligns well with the rise of data-driven applications in today’s development landscape.

Customizable compilation flags

And finally, .NET Core 2.1 introduces customizable compilation flags, enabling developers to fine-tune their applications’ performance and behavior in a more intuitive way. Builders now have greater control over advanced compilation options, such asustering Blocks of code that should be optimized or left as-is. This feature is particularly useful for performance-critical applications, where even minor optimizations can make a significant difference.

In conclusion, .NET Core 2.1 represents a meaningful step forward for the .NET ecosystem, offering developers a more powerful and user-friendly platform to build applications.
