It covers adding ILogger to a controller, logging at different levels, and using structured logging with named placeholders so properties become queryable in Seq. The piece closes by comparing Seq with the author's earlier Serilog-based setup and recommending Seq for local development and quick production debugging. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I send ASP.NET 8 logs to Seq using the built-in ILogger instead of Serilog? Install the Seq.Extensions.Logging NuGet package, then call builder.Services.AddLogging(lb => lb.AddSeq()) during startup. Seq runs locally via Docker on port 5341 by default. Once configured, any ILogger injected into a controller automatically sends its logs to the Seq server, where they can be viewed and queried in the dashboard. _daily.dev surfaces practical setup guides like this for developers wiring up logging pipelines._ ### How do I create structured logs with named properties using ILogger? Use message templates with named placeholders, such as LogInformation("Looking for ID {SearchedId} among {TotalBooksCount} books", id, count). ILogger replaces the placeholders in the output string while also capturing SearchedId and TotalBooksCount as separate structured properties, which sinks like Seq can then use for querying and filtering logs. _developers refining structured logging workflows can find similar deep dives on daily.dev._ ## Similar posts on daily.dev - [Serilog Sinks: Console, File, Seq, and More](https://daily.dev/posts/serilog-sinks-console-file-seq-and-more-k2dux4zvo) · We Are .NET · 2 upvotes · 0 comments - [Structured Logging Patterns That Actually Survive Production — Daily DevOps & .NET](https://daily.dev/posts/structured-logging-patterns-that-actually-survive-production-daily-devops-net-lphiux5cy) · Daily DevOps & .NET · 6 upvotes · 0 comments - [Structured Logging in .NET with Serilog and ClickHouse](https://daily.dev/posts/structured-logging-in-net-with-serilog-and-clickhouse-xwwes1xel) · ClickHouse · 12 upvotes · 1 comments - [Beyond Console.WriteLine: Mastering Structured Logging in .NET](https://daily.dev/posts/beyond-console-writeline-mastering-structured-logging-in-net-hgcoz2ses) · ITNEXT · 10 upvotes · 0 comments - [OpenTelemetry Logging .NET: ILogger Integration and Structured Log Export](https://daily.dev/posts/opentelemetry-logging-net-ilogger-integration-and-structured-log-export-5b3h28qfa) · We Are .NET · 1 upvotes · 0 comments --- Tags: [#logging](https://daily.dev/tags/logging), [#c#](https://daily.dev/tags/c#) [View this post on daily.dev](https://daily.dev/posts/easy-logging-management-with-seq-and-ilogger-in-asp-net-rx9x5hd4g) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Easy logging management with Seq and ILogger in ASP.NET","url":"https://daily.dev/posts/easy-logging-management-with-seq-and-ilogger-in-asp-net-rx9x5hd4g","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/easy-logging-management-with-seq-and-ilogger-in-asp-net-rx9x5hd4g"},"datePublished":"2026-10-04T13:07:01.702Z","dateModified":"2026-10-04T13:15:09.265Z","description":"A walkthrough shows how to install Seq, a free log sink and dashboard, using Docker or a local installer, then wire it into an ASP.NET 8 API via the...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/4643099cebd01c68343461a2ec15555c?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/4643099cebd01c68343461a2ec15555c?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Code4IT","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Code4IT","logo":"https://media.daily.dev/image/upload/s--OaaG4G10--/f_auto,q_auto/v1791119049/logos/code4it?_a=BAMAMicg0","url":"https://daily.dev/sources/code4it"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/easy-logging-management-with-seq-and-ilogger-in-asp-net-rx9x5hd4g","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"logging,c#","timeRequired":"PT8M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Code4IT","item":"https://daily.dev/sources/code4it"},{"@type":"ListItem","position":3,"name":"Easy logging management with Seq and ILogger in ASP.NET"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/easy-logging-management-with-seq-and-ilogger-in-asp-net-rx9x5hd4g#faq","mainEntity":[{"@type":"Question","name":"How do I send ASP.NET 8 logs to Seq using the built-in ILogger instead of Serilog?","acceptedAnswer":{"@type":"Answer","text":"Install the Seq.Extensions.Logging NuGet package, then call builder.Services.AddLogging(lb => lb.AddSeq()) during startup.
