Core.AspNet.Web.Http

ASP.NET Web API on .NET 10 — ApiController, routing, content negotiation, model binding, filters and HttpResponseException.

<PackageReference Include="Core.AspNet.Web.Http" Version="1.0.0" />
<PackageReference Include="Core.AspNet.Web.Http.WebHost" Version="1.0.0" />

Both are needed: this package is the framework, .WebHost is what plugs it into the System.Web pipeline. Core.AspNet.Net.Http.Formatting arrives with it.

Assembly vs package name. The package is Core.AspNet.Web.Http; the assembly inside it is Core.Web.Http. .NET ships an empty System.Web.dll facade in Microsoft.NETCore.App and the host gives the shared framework precedence, so an app-local System.Web.dll is never loaded — the port therefore cannot use the original assembly names. Namespaces are unchanged, so your code and Inherits= attributes are unaffected; only web.config entries that name an assembly need updating.

Registration

Unchanged, in Global.asax:

GlobalConfiguration.Configuration.Routes.MapHttpRoute (
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = System.Web.Http.RouteParameter.Optional });

RouteParameter is deliberately fully qualified: Global.asax imports System.Web.UI.WebControls by default, which has a RouteParameter of its own, and the bare name is ambiguous between the two.

What works

  • ApiController, verb and route-based action selection
  • Content negotiation to JSON and XML, and request-body model binding from both
  • HttpResponseMessage, IHttpActionResult, HttpResponseException mapped to its status
  • Action filters, exception filters, HttpConfiguration and dependency resolution

Version

Web API 1, the generation matching MVC 4. Attribute routing ([Route] on an ApiController) is a Web API 2 feature and is not included — the port supplies attribute routing for MVC only. Use conventional MapHttpRoute templates here.

PORTING-GUIDE.md (step-by-step migration from IIS) and LIMITATIONS.md (what differs from ASP.NET on .NET Framework, and why) ship in the repository.

Licence

Apache-2.0 AND MIT. Microsoft released the ASP.NET Web Stack - the sources this is built from - under the Apache License 2.0. Mono's AssemblyInfo.cs and the code written for this port are MIT. Both are permissive and compatible; the compound expression means the assembly contains code under both, not that you may pick one. THIRD-PARTY-NOTICES.md ships in the package and says which part is which.
