What's New in .NET 10 A Complete Overview
2
.NET 10 is Microsofts latest long-term support
(LTS) release, introducing key updates across
runtime performance, libraries, APIs, and
developer productivity. It enhances scalability,
speeds up execution, and streamlines coding with
new language features and tooling improvements.
This article explores the major changes in .NET
10 and how they benefit developers and businesses
alike.
3
1. Performance Enhancements in .NET Runtime
1.1 JIT Optimization and Devirtualization

• The Just-In-Time (JIT) compiler in .NET 10
  includes several optimizations to improve
  execution time and reduce memory usage
• Devirtualization .NET 10 extends support for
  devirtualization, especially for array interface
  methods. This allows the JIT to convert virtual
  calls to direct calls at runtime, improving
  performance in collection-heavy operations.
• Stack Allocation for Small Fixed-Size Arrays
  Arrays of value types without GC pointers can now
  be stack-allocated, reducing heap pressure and
  improving access speed. This is especially
  beneficial for numerical computing and matrix
  operations.

• Better Tiered Compilation Tiered compilation
  has been fine-tuned to reduce overhead during
  warmup, allowing applications to reach peak
  performance faster.

1.2 AVX 10.2 Support

• AVX (Advanced Vector Extensions) 10.2 is now
  supported for x64 processors, enhancing
  vectorized calculations for future hardware.
• The System.Runtime.Intrinsics.X86.Avx10v2 class
  allows developers to prepare their code for
  future CPU compatibility.
• AVX 10.2 support enhances performance for
  mathematical computations and data processing.

2. Library Updates and New APIs
2.1 Certificate Handling

• A new FindByThumbprint method allows developers
  to locate certificates using hash algorithms
  other than SHA-1.
• This strengthens security and flexibility when
  working with SSL/TLS and secure communications.

2.2 Unicode String Normalization

• Enhanced support for Unicode normalization with
  spans increases the performance of string
  handling.
• CompareOptions.NumericOrdering allows string
  comparison based on numerical value rather than
  character-by-character comparison.

6
2.3 TimeSpan and Date Handling

• TimeSpan.FromMilliseconds has a new overload that
  accepts a single parameter, simplifying the
  syntax for time handling.
• The ISOWeek class now supports DateOnly, making
  it easier to work with week-based date
  calculations.
• Enhanced DateTimeOffset formatting improves
  compatibility with ISO 8601 standards.

2.4 Performance Improvements in Collections

• OrderedDictionaryltTKey,TValuegt includes new
  methods like TryAdd and TryGetValue, which return
  an index to the entry.
• This reduces the need for additional lookup
  operations, improving dictionary performance in
  large datasets.

7
2.5 JSON Serialization and Deserialization

• System.Text.Json now supports ReferenceHandler in
  JsonSourceGenerationOptionsAttribute, improving
  object reference handling in serialization.
• JSON parsing and writing are faster due to better
  memory management and reduced GC pressure.

8
3. SDK and Tooling Enhancements
3.1 Framework Package Pruning

• .NET 10 SDK introduces package pruning to reduce
  unused framework references.
• Applications are now smaller and load faster due
  to fewer unnecessary dependencies.
• The dotnet prune command helps automate this
  process, improving CI/CD pipeline efficiency.

3.2 Hot Reload

• Hot Reload improvements allow changes to C code
  to be applied without restarting the app.
• Enhanced diagnostic messages and faster feedback
  loops boost developer productivity.

9
3.3 NuGet Package Restore Improvements

• Parallel processing for package restores reduces
  build times, especially for large projects.
• Improved caching further reduces network
  dependency and speeds up project load times.

10
4. ASP.NET Core 10 Enhancements
4.1 Blazor and SignalR Updates

• Blazor QuickGrid Enhancements New RowClass
  parameter allows conditional row styling.
• Static Web Asset Improvements Simplified
  handling of static web assets improves build
  performance.
• SignalR Performance Boost Lower latency and
  enhanced connection handling for real-time
  communication.

11
4.2 Minimal APIs and OpenAPI

• Minimal APIs support more complex routing
  scenarios.
• OpenAPI now supports generating OpenAPI 3.1
  documents and serving them in YAML format.
• Endpoint metadata improvements allow for better
  API documentation and testing.

4.3 Authentication and Authorization

• Enhanced support for IKeyedServiceProvider allows
  more granular service resolution in
  authentication and authorization.
• New methods in Microsoft.AspNetCore.Authentication
  simplify token handling.

12
5. .NET MAUI and Mobile Development
5.1 Quality and Performance Improvements

• .NET MAUI includes better error diagnostics and
  stability improvements.
• Support for newer platform-specific APIs improves
  compatibility with iOS, Android, macOS, and
  Windows.

5.2 Accessibility and UI Enhancements

• Improved screen reader support and high-contrast
  themes enhance accessibility.
• Better layout handling reduces UI glitches across
  platforms.

13
6. Entity Framework (EF) Core 10
6.1 LINQ and SQL Translation

• LINQ queries now have better SQL translation,
  reducing query generation time.
• New ExecuteUpdateAsync and ExecuteDeleteAsync
  methods simplify data updates.

6.2 Connection Resiliency

• Improved retry logic for transient failures
  increases database connection reliability.
• Load-balancing support for connection strings
  enhances high-availability scenarios.

14
7. C 14 Features
7.1 Implicit Span Conversions

• Implicit conversions between SpanltTgt and
  ReadOnlySpanltTgt reduce memory copy overhead.
• Enhanced support for readonly ref parameters
  improves performance in low-level code.

7.2 Pattern Matching Enhancements

• New syntax for list patterns simplifies
  collection handling.
• Better support for switch expressions increases
  code readability.

15
7.3 Field-Backed Properties

• Fields can now be backed by auto-properties,
  reducing boilerplate code.
• Enhanced nullability checks improve code safety.

16
8. Windows Forms Enhancements
8.1 Clipboard Handling

• New clipboard APIs support both synchronous and
  asynchronous data transfer.
• Serialization improvements reduce data loss
  during large data transfers.

8.2 High DPI and Theming

• High DPI support improves the appearance of
  Windows Forms apps on modern displays.
• New theming options allow for custom styles and
  dynamic updates.

17
Business and Development Impact

• .NET 10s enhancements in performance, SDK
  tooling, and library support allow businesses to
• Build faster, more scalable applications.
• Improve code quality and reduce debugging time.
• Simplify complex API handling and data
  processing.
• Better cross-platform performance with .NET MAUI
