It covers installing the MiniProfiler.AspNetCore.Mvc NuGet package, wiring it into Startup via UseMiniProfiler and AddMiniProfiler, and defining profiling traces using Step, nested steps, and Inline for async calls. It also explains how to view timing results on the /profiler/results page, tips for getting accurate measurements (Release config, no debugger attached), and notes MiniProfiler supports Entity Framework, Redis, PostgreSQL and works across .NET Framework through .NET 6. The author raises an open question about the meaning of the x-miniprofiler-ids response header and links to a sample GitHub repo and a case study where profiling helped cut an endpoint's response time from 14 seconds to under 3. ## 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 set up MiniProfiler in a .NET 5 API project? Install the MiniProfiler.AspNetCore.Mvc NuGet package, call app.UseMiniProfiler() in the Configure method, and configure it with services.AddMiniProfiler() in ConfigureServices, setting options like RouteBasePath and ColorScheme. Results then appear at the configured path, such as /profiler/results, after you run the app and hit an endpoint. _daily.dev surfaces practical setup walkthroughs like this one for developers adding profiling to .NET APIs._ ### How do I profile nested or async operations with MiniProfiler in C#? Wrap code in a using block with MiniProfiler.Current.Step("name") to create a profiled step, and nest additional Step calls inside it to build a hierarchy of timings. For inline async calls, MiniProfiler.Current.Inline(() => someAsyncCall(), "label") traces the operation and still returns its result. _Developers debugging slow async .NET endpoints can find these tracing patterns on daily.dev._ ### Which .NET versions and dependencies does MiniProfiler support? MiniProfiler works across almost every .NET version, from the older .NET Framework through .NET 6. Beyond core profiling, it offers additional packages for tracing specific dependencies including Entity Framework, Redis, and PostgreSQL. _daily.dev helps teams comparing profiling tool compatibility across .NET Framework and .NET versions._ ## Similar posts on daily.dev - [Today I will… find hidden latency across a distributed .NET application](https://daily.dev/posts/today-i-will-find-hidden-latency-across-a-distributed-net-application-37hqr8by1) · Visual Studio Blog · 8 upvotes · 0 comments - [Enabling the Application Insights Profiler](https://daily.dev/posts/enabling-the-application-insights-profiler-iov3s2yke) · The Art of Simplicity · 0 upvotes · 0 comments - [ASP.NET Core 11 Request Pipeline Performance Deep Dive](https://daily.dev/posts/asp-net-core-11-request-pipeline-performance-deep-dive-y8dxv0kx8) · C\# Corner · 2 upvotes · 0 comments --- Tags: [#performance](https://daily.dev/tags/performance), [#.net](https://daily.dev/tags/.net), [#c#](https://daily.dev/tags/c#), [#aspnet](https://daily.dev/tags/aspnet) [View this post on daily.dev](https://daily.dev/posts/profiling-net-code-with-miniprofiler-jm2wupdwa) ```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":"Profiling .NET code with MiniProfiler","url":"https://daily.dev/posts/profiling-net-code-with-miniprofiler-jm2wupdwa","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/profiling-net-code-with-miniprofiler-jm2wupdwa"},"datePublished":"2026-10-04T13:07:24.348Z","dateModified":"2026-10-04T13:17:03.017Z","description":"A hands-on walkthrough shows how to add MiniProfiler to a .NET 5 API project to find performance bottlenecks.
