I am exploring the features of ASP .NET VNext. In previous versions of .NET, Owin is used for self hosting of applications as well as hosting in any Owin compatible web servers including IIS. As per my understanding, ASP .NET VNext itself is host agnostic and has commands for self hosting of the application. Now, what is the place of Owin in ASP .NET VNext. I have seen many articles taking about Owin and Asp .NET VNext separately but I need to know how to put them together.
I am a beginner.Correct me if I am wrong.
You are right about your confusion. Whatever experience I have with ASP.net vnext (Mainly with VS 2015 Preview and VS 2015 CTP5).
Now let me share something you about OWIN and ASP.net vnext.
As per implementation of ASP.net vnext , OWIN type of pipeline integrated into that. In vnext there is interface called "IApplicationBuilder" and in OWIN "IAppBuilder"
As of now not all component build based on OWIN will not be used in ASP.net vnext but as time goes all component get transfered or have different version for vnext support. As of now in ASP.net vnext you can use Owin component by using IApplicationBuilder extention method UseOWIN.
https://github.com/aspnet/HttpAbstractions/blob/dev/src/Microsoft.AspNet.Owin/OwinExtensions.cs
If you look at Startup.cs file on VS 2015 Preview or CTP5 for ASP.net vnext project then you will get idea then it is somewhat similar concept like Middleware , Register to pipeline.
Surely there is difference between implementation but ASP.net vnext allow to run OWIN component.

As mention below statement from Article link how we can implement in MVC?
Katana allows you to build web based applications, such as MVC or Web API (2) where you can decide which web features to include in the project.
Article link
Katana is no longer being developed. According to their roadmap,
The next major version of Katana is part of the ASP.NET vNext project on GitHub
"ASP.NET vNext" is the early name for what is now ASP.NET Core. The architecture of ASP.NET Core continues (and improves on) the modular architecture that Katana used. You can build an ASP.NET Core MVC project using only the packages you need.
For further reading, check out my answers to Is Owin/Katana supposed to replace Web API? and Does ASP.NET Core still use OWIN?
I can find similar questions, but those answer is not clear or no answer (all answered now) that make me confuse .

Now Visual Studio has 3 Web Project template :
ASP.NET Web Application (.NET Framework) <-- old
ASP.NET Core Web Application (.NET Core) <-- new
ASP.NET Core Web Application (.NET Framework) <-- new
I know the different between .NET Core and .NET Framework.
.Net Core - can cross platform(Windows, OS X, Linux)
.NET Framework - Windows Only
Then, the problem:
If we can use .Net Core in cross platform include Windows,
Why there still need ASP.NET Core Web Application(.NET Framework)(new) ?
If only work on Windows ,
Why don't just use ASP.NET Web Application (.NET Framework)(old)? which much mature and more support.
What is the purpose/usage of ASP.NET Core Web Application (.NET Framework)(new)??
.NET Core does not have all the APIs available in .NET Framework. As a result when running on Windows you may want to target full .NET Framework instead of .NET Core in your Asp.NET Core application.
Asp.NET 4.x is still supported and it's perfectly fine to create new applications using Asp.NET 4.x.
However, the vast majority of innovation goes to Asp.NET Core. Asp.NET Core is also open source so you can actually see the code you are running, debug the code you are running and even contribute back your fixes or new features. Finally, Asp.NET Core is also much more lightweight (everything is a NuGet package and you only include what you need, not coupled to IIS - runs out-of-proces when using IIS) and much faster than ASP.NET.
I am currently checking out asp.net vnext MVC6 in Visual Studio 2015 Preview. I'm pretty new to asp.net in general, but within my company we are going to move towards creating a web api using asp.net for accessing data on our server (currently we only support wcf communication with our own silverlight application). This is the reason I am checking out the new functionalities of MVC 6 to judge whether we should wait before starting our development and use MVC 6 when it is finally released or start development now and create a Web API 2 project.
Anyway, I am looking into auto documenting the web api, which is already integrated into the Visual Studio template for a WebApi 2 project by use of Microsoft.AspNet.WebApi.HelpPage.
Now for my question, is something like this available for MVC 6 aswell? I can import the same package in my project.json in my ASP.NET vNext / MVC6 (whatever you want to call it) project but i can't do app.UseHelpPage(); in my Startup.cs file.
I suspect this is not (yet) integrated in the current release yet. If not, is there anything known about integration of this feature once ASP.NET vNext eventually hits the shelves?
Probably this feature is not available in MVC 6 yet, but you could try Swagger.
Swagger basically is a framework for describing, consuming, and visualizing RESTful APIs.
The nice thing about Swashbuckle that it has no dependency on ASP.NET MVC, so there is no need to include any MVC Nuget packages in order to enable API documentation, as well Swashbuckle contains an embedded version of swagger-ui which will automatically serve up once Swashbuckle is installed.

Can anybody tell me what is ASP.NET vNext?
Every new version on .Net is something like .NET 1.0, .NET 2.0, .NET 3.0, .NET 3.5, .NET 4.0 then why this version is not something like ASP.NET 6.0?
vNext is just the name given to product in the pre-release mode, like c# vNext which will apparently be released as C# 6.0, maybe ASP.NET vNext will have a numbering when it releases.
What is ASP.NET vNext?
Microsoft ASP.NET vNext is a smaller and efficient framework as a result of rebuilding the libraries from ground up.
What's new in vNext
Cloud-optimized versions of MVC, Web API, Web Pages, SignalR, and Entity Framework.
MVC, Web API, and Web Pages will be merged into one framework, called MVC 6.
MVC 6 has no dependency on System.Web. The result is a leaner framework, with faster startup time and lower memory consumption.
vNext is host agnostic. You can host your app in IIS, or self-host in a custom process.
Dependency injection is built into the framework. Use your preferred IoC container to register dependencies.
vNext uses the Roslyn compiler to compile code dynamically. You will be able to edit a code file, refresh the browser, and see the changes without rebuilding the project.
vNext is open source and cross platform.

Sample ASP.NET vNext applications
ASP.NET vNext is the next version of ASP.NET, but it hasn't shipped yet, so it is not an official version. "vNext" is just a working title.
ASP.NET vNext was the code-name for the next generation of ASP.NET, whose official name is ASP.NET 5. As of now ASP.NET 5 is not yet finished and documentation about can be found at http://asp.net/vnext.
ASP.NET 5 is not just an evolution of the previous version(s), it is rebuilt from the ground. Existing ASP.NET applications will run on ASP.NET 5 without modifications, but to take advantage of the new features, such applications will have to be ported to the new version.
Here's a little excerpt of what http://asp.net has to say about ASP.NET 5:
ASP.NET 5 is a lean .NET stack for building modern web apps. We built it from the ground up to provide an optimized development framework for apps that are either deployed to the cloud or run on-premises. It consists of modular components with minimal overhead, so you retain flexibility while constructing your solutions.
ASP.NET 5 includes the following features:
New flexible and cross-platform runtime
New modular HTTP request pipeline
Cloud-ready environment configuration
Unified programming model that combines MVC, Web API, and Web Pages
Ability to see changes without re-building the project
Side-by-side versioning of the .NET Framework
Ability to self-host or host on IIS
New tools in Visual Studio 2015
Open source in GitHub
The changes we made for ASP.NET 5 were based on customer requests and feedback. These changes simplify development, hosting, and maintenance, and are targeted to modern web apps.
Your legacy apps will run on the new version of the ASP.NET without any modifications. However, to take advantage of the new features in ASP.NET 5, you will need to port your existing code to the new framework. You will find many similarities between ASP.NET 5 and earlier versions of ASP.NET, so porting code involves fixing particular issues rather than re-writing the app.
Microsoft is encouraging developers to use asp.net web api for creating Restful services. I have done some googling
http://www.matlus.com/asp-net-web-api-with-webforms/
it seems to me that i can use it with .net 4.5 but not with 4.0. In .net 4.0 what are my options for creating Restful service. is it only wcf web api or something else that should be used?
You can create asp.net web api service without installing .net 4.5, you only need to install asp.net mvc 4 for VS2010 and normally use for .net 4.0. Alternative, you can use WCF service or asp.net mvc controllers for REST architecture, see this example with asp.net mvc
A small mistake of yours, there is no WCF Web Api anymore. That was the original name, then it was renamed ASP.NET Web Api.
You can use it with .NET 4.0. Just install ASP.NET MVC 4 and you get Web Api. But it's still in Beta...
