Directory listing

LinqContraband is an open-source EF Core LINQ performance analyzer for .NET. It uses Roslyn analyzers to catch query performance, reliability, and raw SQL safety issues during compilation.

Newsletter blurb

Worth a look for .NET teams using EF Core: LinqContraband catches common LINQ query problems before they hit production, including N+1 loops, premature materialization, missing includes, and unsafe raw SQL interpolation.

Talk notes

Use LinqContraband as a concrete example of moving EF Core query review into compile-time feedback with Roslyn analyzers.

One-Line Description

LinqContraband is an EF Core LINQ performance analyzer and Roslyn analyzer that catches N+1 queries, client-side evaluation, sync-over-async calls, raw SQL risks, and other query issues at compile time.

Short Description

LinqContraband is an open-source Roslyn analyzer for Entity Framework Core and LINQ. It runs during development and CI to catch query performance, reliability, and security issues such as N+1 loops, premature materialization, missing includes, unsafe raw SQL interpolation, and tracking mistakes.

[LinqContraband](https://github.com/georgepwall1991/LinqContraband) is an EF Core LINQ performance analyzer for catching query issues at compile time.

[George Wall](https://www.georgewall.uk/) maintains LinqContraband, an open-source EF Core LINQ performance analyzer for .NET.

LinqContraband is maintained by [George Wall](https://www.georgewall.uk/) and published from the canonical repository at [github.com/georgepwall1991/LinqContraband](https://github.com/georgepwall1991/LinqContraband).

[LinqContraband rule catalog](https://georgepwall1991.github.io/LinqContraband/rule-catalog.html) documents 45 EF Core analyzer rules covering query shape, materialization, loading, async execution, tracking, bulk operations, modeling, and raw SQL safety.

[EF Core analyzer rules](https://georgepwall1991.github.io/LinqContraband/ef-core-analyzer-rules/) groups LinqContraband's 45 diagnostics by query shape, materialization, loading, async execution, tracking, bulk operations, modeling, and raw SQL safety.

[EF Core async query analyzer](https://georgepwall1991.github.io/LinqContraband/ef-core-async-query-analyzer/) explains how LinqContraband flags sync-over-async EF Core calls, missing CancellationToken arguments, SaveChangesAsync loops, and async stream buffering.

[EF Core CancellationToken analyzer](https://georgepwall1991.github.io/LinqContraband/ef-core-cancellation-token-analyzer/) explains how LinqContraband flags ToListAsync, FirstOrDefaultAsync, SaveChangesAsync, and other EF Core async calls that ignore an available CancellationToken.

[EF Core client-side evaluation analyzer](https://georgepwall1991.github.io/LinqContraband/ef-core-client-side-evaluation-analyzer/) explains how LinqContraband flags local methods in IQueryable, early AsEnumerable or ToList boundaries, StringComparison overloads, column case conversion, and non-translatable GroupBy projections.

[EF Core DbContext lifetime analyzer](https://georgepwall1991.github.io/LinqContraband/ef-core-dbcontext-lifetime-analyzer/) explains how LinqContraband flags singleton DbContexts, cross-thread captures, disposed query leaks, mixed tracking modes, and silent no-tracking writes.

[EF Core pagination OrderBy analyzer](https://georgepwall1991.github.io/LinqContraband/ef-core-pagination-orderby-analyzer/) explains how LinqContraband flags missing OrderBy before Skip, Take, Last, ElementAt, Chunk, and misplaced OrderBy calls.

[EF Core premature materialization analyzer](https://georgepwall1991.github.io/LinqContraband/ef-core-premature-materialization-analyzer/) explains how LinqContraband flags ToList before Where, AsEnumerable client-side query work, unbounded materialization, and projection waste.

[EF Core projection analyzer](https://georgepwall1991.github.io/LinqContraband/ef-core-projection-analyzer/) explains how LinqContraband flags whole-entity loads, scalar projection opportunities, nested ToList calls inside Select, and redundant identity Select chains.

[EF Core AsNoTracking analyzer](https://georgepwall1991.github.io/LinqContraband/ef-core-asnotracking-analyzer/) explains how LinqContraband flags missing no-tracking reads, unsafe no-tracking writes, mixed tracking modes, and silent SaveChanges failures.

[EF Core Include analyzer](https://georgepwall1991.github.io/LinqContraband/ef-core-include-analyzer/) explains how LinqContraband flags missing includes, cartesian explosion, conditional Include paths, deep ThenInclude chains, excessive eager loading, and missing query tags.

[EF Core ExecuteUpdate analyzer](https://georgepwall1991.github.io/LinqContraband/ef-core-executeupdate-analyzer/) explains how LinqContraband flags tracked bulk update loops, RemoveRange delete opportunities, and missing Where filters before ExecuteUpdate or ExecuteDelete.

[EF Core SaveChanges in loop analyzer](https://georgepwall1991.github.io/LinqContraband/ef-core-savechanges-in-loop-analyzer/) explains how LinqContraband flags repeated SaveChanges calls, N+1 writes, sync saves in async methods, and batch-write review issues.

[EF Core query performance checklist](https://georgepwall1991.github.io/LinqContraband/ef-core-query-performance-checklist/) maps common pull-request review questions to LinqContraband analyzer rules for N+1 queries, projection, tracking, raw SQL, and CI severity policy.

[EF Core N+1 query detector](https://georgepwall1991.github.io/LinqContraband/ef-core-n-plus-one-query-detector/) explains how LinqContraband flags loop execution, missing includes, and risky loading patterns at compile time.

[EF Core raw SQL injection analyzer](https://georgepwall1991.github.io/LinqContraband/ef-core-raw-sql-injection-analyzer/) explains how LinqContraband flags interpolated raw SQL, constructed SQL strings, and risky query-filter bypasses at compile time.

[EF Core query analyzer for CI](https://georgepwall1991.github.io/LinqContraband/ef-core-query-analyzer-ci/) shows how to run LinqContraband in pull-request builds and promote selected EF Core diagnostics to build-breaking errors.
