src/X.PagedList.EntityFramework/README.md (1)
13-17: Tighten wording and add a short “EF6 is legacy” note
- Small grammar tweak.
- Since the PR positions EF6 as deprecated/legacy, add a brief note to set expectations and point EF Core users to the alternative.

3-9: Consider silencing EF6 deprecation warning locally (optional)EF6 NuGet may emit NU1903 (deprecated). If your CI treats warnings as errors (now or in the future), builds can break. It’s reasonable to suppress this warning in this EF6-only project.
Optional addition:
<PropertyGroup> <Title>X.PagedList.EntityFramework</Title> <Description>Entity Framework 6 (legacy) extensions for X.PagedList library</Description> <LangVersion>default</LangVersion> <TargetFrameworks>net481;netstandard2.1</TargetFrameworks> <PackageTags>paging pagedlist paged list entity framework ef6</PackageTags> + <NoWarn>$(NoWarn);NU1903</NoWarn> </PropertyGroup>src/X.PagedList.EntityFramework/PagedListExtensions.cs (8)
39-47: Prefer ArgumentOutOfRangeException overloads with paramName and actual valuePassing only a message omits param metadata. Use the overloads that include paramName and actual value for better diagnostics.
Apply this diff:
- throw new ArgumentOutOfRangeException($"pageNumber = {pageNumber}. PageNumber cannot be below 1."); + throw new ArgumentOutOfRangeException(nameof(pageNumber), pageNumber, "PageNumber must be greater than or equal to 1."); - throw new ArgumentOutOfRangeException($"pageSize = {pageSize}. PageSize cannot be less than 1."); + throw new ArgumentOutOfRangeException(nameof(pageSize), pageSize, "PageSize must be greater than or equal to 1.");
52-56: Validate provided total count is non-negativeIf callers pass a negative totalSetCount, you’ll propagate an invalid count into StaticPagedList metadata. Guard against this.
- if (totalSetCount.HasValue) - { - totalCount = totalSetCount.Value; - } + if (totalSetCount.HasValue) + { + if (totalSetCount.Value < 0) + throw new ArgumentOutOfRangeException(nameof(totalSetCount), totalSetCount, "Total item count cannot be negative."); + totalCount = totalSetCount.Value; + }
63-76: Avoid round-trip when page is beyond range; use Array.Empty for empty subsetWhen skip >= totalCount, a Skip/Take call does an unnecessary DB query. Also, prefer Array.Empty() for the empty case to avoid a list allocation.
- if (totalCount > 0) - { - int skip = (pageNumber - 1) * pageSize; - - subset = await superset - .Skip(skip) - .Take(pageSize) - .ToListAsync(cancellationToken) - .ConfigureAwait(false); - } - else - { - subset = new List<T>(); - } + int skip = (pageNumber - 1) * pageSize; + if (totalCount <= 0 || skip >= totalCount) + { + subset = Array.Empty<T>(); + } + else + { + subset = await superset + .Skip(skip) + .Take(pageSize) + .ToListAsync(cancellationToken) + .ConfigureAwait(false); + }
11-16: Fix XML doc to reference the actual public surfaceDocs say PagedList but this API returns IPagedList backed by StaticPagedList. Also minor wording.
-/// EntityFramework extension methods designed to simplify the creation of instances of <see cref="PagedList{T}"/>. +/// Entity Framework 6 extension methods that help create instances of <see cref="IPagedList{T}"/> (backed by <see cref="StaticPagedList{T}"/>).
22-27: Tighten parameter XML docs and fill missing cancellation token descriptionClarify that the source must be an EF6 IQueryable and recommend explicit ordering; add a description for cancellationToken.
-/// <param name="superset">The collection of objects to be divided into subsets. If the collection implements <see cref="IQueryable{T}"/>, it will be treated as such.</param> +/// <param name="superset">The EF6 <see cref="IQueryable{T}"/> query to page. Ensure a deterministic ordering (e.g., via <c>OrderBy</c>) for stable paging.</param> /// <param name="pageNumber">The one-based index of the subset of objects to be contained by this instance.</param> /// <param name="pageSize">The maximum size of any individual subset.</param> -/// <param name="totalSetCount">The total size of set</param> -/// <param name="cancellationToken"></param> +/// <param name="totalSetCount">Optional total item count for the full set, when known. If omitted, a <c>CountAsync</c> query will be executed.</param> +/// <param name="cancellationToken">Cancellation token to cancel the underlying database operations.</param>
31-32: Update see-also to match usage/return typesThe implementation returns StaticPagedList as IPagedList; update the reference accordingly.
-/// <seealso cref="PagedList{T}"/> +/// <seealso cref="StaticPagedList{T}"/>
25-25: Consider renaming totalSetCount to totalItemCount for consistency with X.PagedList terminologyX.PagedList commonly uses “totalItemCount.” Since this is a new public API, aligning now avoids future breaking changes.
-/// <param name="totalSetCount">Optional total item count for the full set, when known. If omitted, a <c>CountAsync</c> query will be executed.</param> +/// <param name="totalItemCount">Optional total item count for the full set, when known. If omitted, a <c>CountAsync</c> query will be executed.</param> @@ - public static async Task<IPagedList<T>> ToPagedListAsync<T>(this IQueryable<T> superset, int pageNumber, int pageSize, int? totalSetCount, CancellationToken cancellationToken) + public static async Task<IPagedList<T>> ToPagedListAsync<T>(this IQueryable<T> superset, int pageNumber, int pageSize, int? totalItemCount, CancellationToken cancellationToken) @@ - if (totalSetCount.HasValue) + if (totalItemCount.HasValue) { - if (totalSetCount.Value < 0) - throw new ArgumentOutOfRangeException(nameof(totalSetCount), totalSetCount, "Total item count cannot be negative."); - totalCount = totalSetCount.Value; + if (totalItemCount.Value < 0) + throw new ArgumentOutOfRangeException(nameof(totalItemCount), totalItemCount, "Total item count cannot be negative."); + totalCount = totalItemCount.Value; } @@ -/// <param name="totalSetCount">The total size of set</param> +/// <param name="totalItemCount">The total number of items in the full set.</param> @@ - public static Task<IPagedList<T>> ToPagedListAsync<T>(this IQueryable<T> superset, int pageNumber, int pageSize, int? totalSetCount = null) + public static Task<IPagedList<T>> ToPagedListAsync<T>(this IQueryable<T> superset, int pageNumber, int pageSize, int? totalItemCount = null) { - return ToPagedListAsync(superset, pageNumber, pageSize, totalSetCount, CancellationToken.None); + return ToPagedListAsync(superset, pageNumber, pageSize, totalItemCount, CancellationToken.None); }Also applies to: 32-32, 52-56, 89-89, 95-97
67-71: Reminder: ensure upstream queries apply ordering before Skip/TakeEF does not guarantee ordering unless specified. Without OrderBy, paging is nondeterministic. Consider documenting this in README and examples for this new package.
I can open a follow-up PR to update README.md with an ordering note and example if you’d like.

src/Directory.Build.props (1)
13-16: Version bump to 10.5.7 looks consistent and scoped correctlyAll four version fields are aligned. No issues spotted.
src/X.PagedList/X.PagedList.csproj (1)
8-8: Add net481 target — LGTMThe expanded TFM set aligns with EF6 compatibility requirements. No other changes needed.
src/X.PagedList.EntityFramework/X.PagedList.EntityFramework.csproj (2)
20-21: Dependency choice and range look correct
- EF pinned to [6.5.1,7.0.0) ensures latest EF6 without accidentally flowing into EF Core.
- JetBrains.Annotations is private — good.
No changes requested.
25-25: EF6 async extensions verified
src/X.PagedList.EntityFramework/PagedListExtensions.csincludesusing System.Data.Entity;- Uses
await superset.CountAsync(cancellationToken).ConfigureAwait(false)- Uses
await superset.Skip(skip).Take(pageSize).ToListAsync(cancellationToken).ConfigureAwait(false)All EF6 async methods are correctly used.
X.PagedList.slnx (1)
1-16: No CI/docs references to .sln – .slnx-only solution is safe
A search across all YAML, XML, Markdown and shell scripts for “.sln” ordotnet build *.slnreturned no hits. There are no CI workflows or docs depending on an old.sln, so you can proceed with the.slnxfile alone.
Optional: if you have contributors who rely on Visual Studio’s classic solution format, you may still include a legacy.slnor document how to open the.slnx.src/X.PagedList.EntityFramework/PagedListExtensions.cs (3)
32-79: EF6 async paging implementation is solidCountAsync/ToListAsync with ConfigureAwait(false), null/arg validation, and returning StaticPagedList look correct. This should integrate well with EF6.
58-61: Good use of ConfigureAwait(false) in library codeUsing ConfigureAwait(false) on EF6 async calls is the right choice for a library.
Also applies to: 70-71
9-9: File-scoped namespace is supported under your SDK-style setupI’ve confirmed that
X.PagedList.EntityFramework.csprojis an SDK-style project with<LangVersion>default</LangVersion>. When built with the .NET SDK (v6+), “default” maps to C# 10+, so file-scoped namespaces will compile as expected. No changes needed here.

Fix package name in title and use HTTPS for badges
- Title says “X.Extensions.PagedList.EF6” but the project/package is X.PagedList.EntityFramework. This will confuse users.
- The NuGet badge uses http; prefer https to avoid mixed-content warnings.
Apply:
-# X.Extensions.PagedList.EF6

In src/X.PagedList.EntityFramework/README.md around lines 1 to 5, the README
title incorrectly says "X.Extensions.PagedList.EF6" and the NuGet badge uses an
http URL; change the title to "X.PagedList.EntityFramework" to match the
project/package name and update the NuGet badge URL to use https
