In .NET 10, the JIT can stack-allocate small fixed-size arrays of value types, eliminating heap allocations and delivering up to 60% faster performance compared to .NET 9.

A summary of new features, improvements, and breaking changes in .NET MAUI 10, released with .NET 10 and C# 14 in November 2025.

C# 14 allows using ref, out, in, scoped, and ref readonly modifiers on implicitly typed lambda parameters, eliminating the need to explicitly declare parameter types.

C# 14 lets you declare instance constructors and events as partial members, splitting definitions across files for cleaner code generation and separation of concerns.

C# 14 enhances the nameof expression to support unbound generic types like List<> and Dictionary<,>, eliminating the need for placeholder type arguments.

C# 14 adds built-in implicit conversions between Span, ReadOnlySpan, arrays, and strings, enabling cleaner APIs, better type inference, and fewer manual AsSpan() calls.

In .NET 10, the JIT compiler reduces the overhead of iterating arrays through interfaces. See benchmarks comparing .NET 9 vs .NET 10 with foreach, IEnumerable, and conditional escape analysis.

C# 14 introduces the field contextual keyword for property accessors, letting you add custom logic to auto-properties without declaring a separate backing field.

.NET 9 significantly improves ToArray performance using InlineArray, making it faster and more memory-efficient than ToList. See benchmarks comparing .NET 8 vs .NET 9.
