Pull request overview
This PR continues the migration away from fixed buffers in structs by using C# inline arrays (InlineArray / InlineArrayN<T>) and span-based access patterns, primarily in interop and low-level encoding/networking code.
Changes:
- Replace
fixedbuffers with inline arrays (and conditional#if NETfallbacks where needed). - Update call sites to use span slicing / pointer casts compatible with inline-array-backed fields.
- Adjust a few Windows interop usages (WinHTTP connection info, RtlGetVersion / OS version string, time zone structs) to work with the new buffer representations.

Pull request overview
This PR continues the ongoing effort to remove fixed buffers and unsafe string/pointer patterns by adopting C# inline arrays ([InlineArray] / InlineArrayN<T>) and span-based accessors across interop-heavy areas.
Changes:
- Replaced multiple fixed-size buffers in interop structs (WinHTTP, NtDll, Kernel32 timezone, msquic, Unix network info) with inline arrays.
- Updated call sites to use span conversions / slicing instead of pointer-based access and
Buffer.MemoryCopy. - Simplified a few APIs by removing
unsafewhere it’s no longer required (e.g., OS version string handling).

This PR continues the repo-wide effort to replace fixed buffers with C# InlineArray-based representations, reducing unsafe usage while keeping the same native layouts for interop-heavy structs.
Changes:
- Replace multiple
fixedbuffer fields in interop structs withInlineArray*<T>or[InlineArray(N)]buffer structs (often under#if NET). - Update call sites to use span casts / slicing instead of pointer-based span construction or
Buffer.MemoryCopy. - Remove some

Pull request overview
This PR continues the effort to reduce unsafe fixed buffers by replacing them with C# inline arrays (InlineArrayN<T> or [InlineArray(N)] buffers), primarily in interop structs and related call sites, so the code can rely more on spans and less on raw pointers.
Changes:
- Replace multiple fixed-size buffers in interop structs with inline arrays (including
InlineArray2/3/4/8/16<T>and custom[InlineArray(N)]buffers). - Update consumers to use span-based access patterns (casts to
Span<T>/ReadOnlySpan<T>, slicing) rather thanfixed+ pointer arithmetic. - Adjust a few APIs to no longer require
unsafeat the method level when it’s no longer needed.

Pull request overview
This PR continues the repo-wide modernization effort to remove fixed buffers in favor of C# InlineArray patterns, reducing unsafe usage and simplifying buffer access across tasks, libraries, and interop layers.
Changes:
- Replaced multiple
fixedbuffers withInlineArray(or[InlineArray(N)]-annotated buffers) in interop structs and internal helpers. - Updated call sites to use span-based indexing/slicing for these buffers (e.g.,
ReadOnlySpan<T>/Span<T>conversions and range slicing). - Simplified some Windows string extraction from inline buffers by using
ReadOnlySpan<char>+ null-terminator search rather than pointer-basednew string(char*).

Pull request overview
This PR continues the repo-wide migration away from fixed buffers, replacing remaining fixed-size buffers with C# inline arrays (either the built-in InlineArrayN<T> types or [InlineArray(N)]-annotated buffers) and updating call sites to use span-based access patterns.
Changes:
- Replace fixed buffers in several interop / header structs with inline array buffers under
#if NET(keepingfixedbuffers for non-NET targets where needed). - Update consumers to use span indexing / slicing for inline-array-backed buffers (e.g., MAC addresses, IP addresses, SOCKADDR storage, OS version strings).
- Minor safety / clarity adjustments related to definite assignment and null-terminated string extraction.
