It uses Stopwatch.GetTimestamp wrapped in try/finally and writes to Trace by default, but supports a custom static MethodTimeLogger class to route timings to Serilog, Application Insights, or other loggers. A format string on the attribute can include parameter values or {this} in the logged message. It's recommended for development diagnostics rather than rigorous benchmarking, where BenchmarkDotNet is suggested instead. ## 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 measure method execution time in .NET without writing Stopwatch code in every method? MethodTimer.Fody weaves timing code into methods at compile time when you decorate them with a [Time] attribute, so no manual Stopwatch calls are needed in the source. It uses Stopwatch.GetTimestamp wrapped in a try/finally block and writes the elapsed time to Trace by default, with the attribute itself removed from the compiled assembly. _daily.dev surfaces practical .NET performance patterns like this for developers cleaning up timing boilerplate._ ### How do I send MethodTimer.Fody timing output to Serilog instead of Trace.WriteLine? Define a static MethodTimeLogger class with a Log method, and MethodTimer.Fody calls it instead of writing to Trace. Two signatures are supported: Log(MethodBase, TimeSpan, string) or Log(MethodBase, long, string), with the TimeSpan overload preferred when both exist; from there the elapsed time can be routed into Serilog, Application Insights, or any logging pipeline. _developers wiring custom loggers into timing libraries can find walkthroughs like this on daily.dev._ ### Can I include method parameter values in MethodTimer.Fody timing logs? Yes, MethodTimer.Fody supports a format string on the [Time] attribute, such as [Time("Days: {days}")], which includes parameter values in the logged message. Allowed placeholders are parameter names and {this} for the instance's ToString() value, though sub-properties are not supported, and this requires a MethodTimeLogger.Log overload that accepts a message parameter or the build fails. _daily.dev helps developers track configuration details like these when adopting a new timing library._ ## Similar posts on daily.dev - [sebastienros/comptime: Comptime brings meta-programming capabilities to C\#, enabling compile-time code generation and evaluation.](https://daily.dev/posts/sebastienros-comptime-comptime-brings-meta-programming-capabilities-to-c-enabling-compile-time-co-l1shyzlio) · Hacker News · 11 upvotes · 0 comments - [Stop Pretending TimeProvider Doesn't Exist — Daily DevOps & .NET](https://daily.dev/posts/stop-pretending-timeprovider-doesn-t-exist-daily-devops-net-8lez0ga1i) · We Are .NET · 21 upvotes · 1 comments - [Tracking Time Without Clock](https://daily.dev/posts/tracking-time-without-clock-x7gtqv6gr) · Lobsters · 0 upvotes · 0 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 --- Tags: [#performance](https://daily.dev/tags/performance), [#.net](https://daily.dev/tags/.net), [#logging](https://daily.dev/tags/logging), [#c#](https://daily.dev/tags/c#) [View this post on daily.dev](https://daily.dev/posts/methodtimer-by-fody-in-net-yerk6dyvm) ```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":"MethodTimer by Fody in .NET","url":"https://daily.dev/posts/methodtimer-by-fody-in-net-yerk6dyvm","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/methodtimer-by-fody-in-net-yerk6dyvm"},"datePublished":"2026-10-04T13:07:03.169Z","dateModified":"2026-10-04T13:12:06.075Z","description":"MethodTimer.Fody is a compile-time weaver that injects method timing code via a [Time] attribute, eliminating manual Stopwatch boilerplate.
