The major version drops the ASP.NET SiteMapProvider implementation model in favor of a cleaner, fully pluggable architecture with improved dependency injection support, including NuGet packages for Ninject, StructureMap, Unity, Autofac, and Windsor. The sitemap building pipeline now uses a collection of builders and visitors that can be customized or replaced. The Menu() helper was rewritten for better performance. Upgrading from v3 requires uninstalling the old package and installing a version-specific one, since the single NuGet package has been split into multiple packages; a full upgrade guide is provided. ## 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 upgrade MvcSiteMapProvider from v3 to v4? Uninstall the old MvcSiteMapProvider package and install the version-specific package for your ASP.NET MVC version, such as MvcSiteMapProvider.MVC4, MvcSiteMapProvider.MVC3, or MvcSiteMapProvider.MVC2. The single NuGet package was split into multiple packages, including MvcSiteMapProvider.Web for views and web.config changes and a Core package for the library. On MVC4 it is possible to upgrade the old MvcSiteMapProvider package directly, but installing MvcSiteMapProvider.MVC4 separately is recommended instead. _daily.dev keeps developers planning a sitemap library upgrade on top of breaking package changes like this._ ### What changed in MvcSiteMapProvider 4.0 compared to earlier versions? MvcSiteMapProvider 4.0 stepped away from being an ASP.NET SiteMapProvider implementation, requiring a substantial code rewrite. It added pluggable dependency injection with packages for Ninject, StructureMap, Unity, Autofac, and Windsor, introduced a new sitemap building pipeline using replaceable builders and visitors, rewrote the Menu() helper for better performance, and included various stability fixes. _Developers evaluating ASP.NET MVC sitemap tooling can track architecture changes like these via daily.dev._ ## Similar posts on daily.dev - [htmxRazor v1.4.0: SSE Streaming, Multi-step Wizard, and Optimistic UI - Chris Woody Woodruff](https://daily.dev/posts/htmxrazor-v1-4-0-sse-streaming-multi-step-wizard-and-optimistic-ui---chris-woody-woodruff-djatrl3bc) · We Are .NET · 20 upvotes · 0 comments - [How to Upgrade ASP.NET MVC to .NET Step by Step](https://daily.dev/posts/how-to-upgrade-asp-net-mvc-to-net-step-by-step-i3p1uesfs) · C\# Corner · 2 upvotes · 0 comments - [Explore What’s New in SkiaSharp 4.0](https://daily.dev/posts/explore-what-s-new-in-skiasharp-4-0-pbe3w4yhs) · Uno Platform · 17 upvotes · 1 comments - [htmxRazor v2.0.0: Platform and DX - Chris Woody Woodruff](https://daily.dev/posts/htmxrazor-v2-0-0-platform-and-dx---chris-woody-woodruff-gyh7wczzb) · We Are .NET · 0 upvotes · 0 comments - [SkiaSharp 4.0 Establishes Milestone-Aligned Release Cadence](https://daily.dev/posts/skiasharp-4-0-establishes-milestone-aligned-release-cadence-cnqoznuu4) · InfoQ · 4 upvotes · 0 comments --- Tags: [#c#](https://daily.dev/tags/c#), [#dependency-injection](https://daily.dev/tags/dependency-injection), [#nuget](https://daily.dev/tags/nuget) [View this post on daily.dev](https://daily.dev/posts/just-released-mvcsitemapprovider-4-0-evsmuecog) ```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":"Just released: MvcSiteMapProvider 4.0","url":"https://daily.dev/posts/just-released-mvcsitemapprovider-4-0-evsmuecog","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/just-released-mvcsitemapprovider-4-0-evsmuecog"},"datePublished":"2026-10-04T13:04:30.831Z","dateModified":"2026-10-04T13:36:46.797Z","description":"MvcSiteMapProvider 4.0 has shipped as a stable release for ASP.NET MVC after a six-month development cycle and a beta a month prior.
