We are migrating our project from ASP.NET Web API to ASP.NET Core 6.0 Web API as part of that we having following below lines of code.
DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
config.DependencyResolver = new AutofacWebApiDependencyResolver(container);
The config is a HTTPConfiguration but while migrating to .NET 6.0 I was not able to access HTTpConfiguration from WebApplicationBuilder or WebApplication.
Please let me know how to access HttpConfiguration in .NET 6.0 and assign the DependencyResolver.
In .NET Core you don't explicitly set the dependency resolver and there's no HttpConfiguration. It's a whole different application and hosting model. I'd recommend following some of the tutorials about ASP.NET Core - it's similar, but different enough that the answer to this question would basically be to replicate all the existing migration docs and tutorials already on the Microsoft doc site.

We have implemented OWIN Authorization to our Web Api's in .Net framework project. Now we are migrating this to .Net6. It seems in .net6/.net core owin authentication is not supported.
I don't find any documentation around this.
It seems Microsoft.Owin.OwinMiddleware is not exits in .net core.Also I don't find any Microsoft.Owin.Security.Infrastructure.AuthenticationTokenProvider corresponding nuget packages in .net core.
How can we use OWIN Authorization in .Net core(.net6)? If it is not supported what is alternative to this in .net core
ASP.NET Core using a new authentication middleware which could work like OWIN.
So you could directly using this middleware instead of using owin inside the asp.net core.
For example, if you want to include the MSFT, Goolge, facebook or else, you could refer to this article.
In .NET framework we have support of Creating Help Page for Web API.
https://learn.microsoft.com/en-us/aspnet/web-api/overview/getting-started-with-aspnet-web-api/creating-api-help-pages
Does this feature supported in .NET 6. We are migrating our legacy ASP.NET framework application to .NET6.
How to migrate this feature to .NET6? If it is not supported in .Net6(.net core) how can we achieve the similar functionality in .Net core
I am trying to migrate this feature to .net core but I am facing issues on how to load the app data, register HelpdataConfig in .net core.

As you can see in ASP.NET help page for ASP.NET Core Web API, the Microsoft.AspNet.WebApi.HelpPage is for ASP.NET and does not for ASP.NET CORE or .NET 6, so you have to migrate this library to some popular Web API documentation libraries like Swagger
As you can see in ASP.NET Core web API documentation with Swagger / OpenAPI, you can use below documentation
By Christoph Nienaber and Rico Suter
Swagger (OpenAPI) is a language-agnostic specification for describing REST APIs. It allows both computers and humans to understand the capabilities of a REST API without direct access to the source code. Its main goals are to:
Minimize the amount of work needed to connect decoupled services.
Reduce the amount of time needed to accurately document a service.
The two main OpenAPI implementations for .NET are Swashbuckle and NSwag, see:

We have a SignalR service that runs as a self-hosted OWIN app with Web API 2. It is configured like
resolver.Register(typeof(JsonSerializer), () => JsonSerializer.Create(serializerSettings));
app.MapSignalR(new HubConfiguration { EnableDetailedErrors = true, Resolver = resolver});
We want to replace our JsonSerializer with MessagePack. The obvious examples all configure it from a AspNet.Core web application context. I can't seem to find any examples with Owin self hosting.
EDIT: It looks like MessagePack is a new ASP.NET Core feature. We are running the older ASP.NET version and so I guess the real question is how to do binary formatting over ASP.NET SignalR.
It's not possible. I am migrating my solution to the AspNetCore version of SignalR.
Our app is based on ASP.NET Core 2.0. It works fine in development environment but we see an oauth error when published to production.
All the documentation on asp.net core seems to point to using ILoggingxxx interfaces. The examples I found typically call logging.AddConsole() method so that the log lines can be viewed in VIsual Studio debug window. I am wondering if the good old trace.axd is still available under asp.net core. If so, I would appreciate the steps to enable tracing. Regards.
trace.axd is exclusive to applications based on .NET Framework and ASP.NET 4.x. It is not available in ASP.NET Core applications at all.
Is there an MVC6 compatible version of WebTelemetryInitializerBase that would work with ASP.NET Core (on the full .NET Framework)?
See my question here where I asked how to get HttpContext in my temeletry initializers. Unfortunately I didn't specify that I was using MVC 6 and thus no System.Web.HttpContext.
Yes, there is a version of this for aspnetcore. Check out the Microsoft Application Insights for ASP.NET Core applications repo.
There is an implementation of getting the WebUser found in /src/Microsoft.ApplicationInsights.AspNetCore/TelemetryInitializers/WebUserTelemetryInitializer.cs which you can use as a guide.
The TelemetryInitializerBase class is the one that consumes the IHttpContextAccessor which is used to get the HttpContext.
From there you can get the Microsoft.AspNetCore.Http.HttpContext.User which is they type of System.Security.Claims.ClaimsPrincipal
