.NET 10 introduces a suite of powerful features and enhancements that can significantly boost your application's performance and efficiency. Let's dive into some of the most notable improvements and how you can leverage them in your development work.

Enhancements to the ZipArchive Class

One of the standout features in .NET 10 is the enhancement to the ZipArchive class, which brings substantial performance and memory improvements. Here's what's new:

  • Optimized Update Mode: Previously, updating a file within a ZIP archive required loading the entire archive into memory, consuming significant resources. In .NET 10, file updates are handled more efficiently, reducing memory consumption.
  • Parallelized Extraction: The process of decompressing files from ZIP archives has been sped up through parallelization. Data is processed in parallel, and memory consumption has been optimized, making extraction faster and more efficient.

How You Can Use It

If your applications work with ZIP archives, you'll notice faster and more efficient handling of these files. Updating large files within a ZIP or extracting multiple files simultaneously will benefit from these improvements.

Benefits

  • Reduced Memory Consumption: Particularly noticeable when dealing with large or numerous ZIP archives.
  • Improved Performance: Faster ZIP update and extraction operations make your applications more responsive.

C# 14 Features

.NET 10 also introduces several new features in C# 14 that enhance productivity and code readability:

  • Field-backed Properties: Simplifies creating properties with custom getter/setter logic by allowing direct access to the compiler-generated backing field using the field keyword. 
public class MyClass
  {
      private int _myField;
      public int MyProperty
      {
          get => field; // Accessing the backing field
          set { field = Math.Max(0, value); }
      }
  }
  • Implicit Conversions for Span and ReadOnlySpan: Provides first-class language support for these types, allowing implicit conversions in more scenarios.
  • Unbound Generics in nameof: Obtain the name of an unbound generic type without specifying concrete type arguments.
  • Modifiers on Lambda Parameters: Add modifiers like ref, in, or out directly to lambda parameters for more concise expressions.

ASP.NET Core 10 Features

ASP.NET Core 10 brings several enhancements to web API development:

  • OpenAPI 3.1 Support: Generate OpenAPI documents conforming to the latest specification, with improved JSON Schema alignment.
  • Serving OpenAPI in YAML: Provides OpenAPI documentation in a more human-readable YAML format.

Blazor Enhancements

Blazor continues to evolve with new features in .NET 10:

  • ReconnectModal Component: A built-in way to handle UI during reconnections between the client and server.
  • QuickGrid Improvements: Supports the RowClass parameter for applying CSS classes to rows and CloseColumnOptionsAsync for programmatically closing column options.
  • Blazor Script as Static Web Asset: Improves performance through precompression and browser caching.

EF Core 10 Features

Entity Framework Core 10 introduces new capabilities for data access:

  • LeftJoin/RightJoin Operators: Simplifies writing LINQ queries involving these types of joins.
  • Improved ExecuteUpdateAsync: Accepts regular lambda expressions for specifying updates, making it more convenient to use.

Conclusion

.NET 10 brings a wealth of improvements across various domains, from language features to web API enhancements and framework updates for Blazor and EF Core. These features offer practical benefits that can significantly enhance your .NET development work.
