I have read many articles about the OWIN and Katana projects, but I could not get the whole picture of it. For a normal web developer who uses ASP.NET: What exactly is OWIN and what problems does it solve (in simple words). What is its relation to IIS? Does OWIN replace IIS? if not, in what situations does OWIN best fit? How could OWIN help me in my daily work projects? How could OWIN help me in a self-improvement projects? Admir Tuzović Regarding the comment above, OWIN is not a framework. OWIN is a specification on how web servers and web applications should be built in order to decouple

Microsoft recently introduced new ASP.NET Identity - replacement for old (Simple)Membership. Unfortunately, I can't use this new membership system in my old project because it throws System.InvalidOperationException: No owin.Environment item was found in the context. This is a known bug , but Microsoft keeps silence about this issue. The easiest way to reproduce this bug - it's to create a new web application (MVC, WebForms or WebApi - doesn't matter) in VS 2013 (with Web Tools 2013 Preview Refresh) and then go to the login page. It will work. Then change namespace in your application to

When I setup an OAuth Authorization Server in asp.net webapi 2 how can I set the token endpoint to accept json rather then a form encoded post? Using the sample http://www.asp.net/web-api/overview/security/individual-accounts-in-web-api I tried to send application/json with { "grant_type":"password", "username":"Alice", "password":"password123" } I receive the response 400 Bad Request { "error" : "unsupported_grant_type" } where as a content type of application/x-www-form-urlencoded and body of grant_type=password&username=Alice&password=password123 works as expected. 200 OK { "access_token" :

I decided to give the new Google Oauth2 middleware a try and it has pretty much broken everything. Here is my provider config from startup.auth.cs.. When turned on, all of the providers including the google provider get a 500 internal server on Challenge. However the details of the internal server error are not available and I cant figure out how to turn on any debugging or tracing for the Katana middleware. Seems to me like they were in a rush to get the google Oauth middleware out the door. //// GOOGLE var googleOptions = new GoogleOAuth2AuthenticationOptions { ClientId = "228", ClientSecret

In my application i am using web api with token based authentication with CORS support, but when client request for the token, an error occured due to CORS (Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at (my site name) . This can be fixed by moving the resource to the same domain or enabling CORS.) I had configured everything required for CORS support ( i think so). here my configuration Owin start up class public class Startup { public void Configuration(IAppBuilder app) { var config = new HttpConfiguration { DependencyResolver = new

I'm trying to create a unified error handling/reporting in ASP.NET Web API 2.1 Project built on top of OWIN middleware (IIS HOST using Owin.Host.SystemWeb). Currently I used a custom exception logger which inherits from System.Web.Http.ExceptionHandling.ExceptionLogger and uses NLog to log all exceptions as the code below: public class NLogExceptionLogger : ExceptionLogger { private static readonly Logger Nlog = LogManager.GetCurrentClassLogger(); public override void Log(ExceptionLoggerContext context) { //Log using NLog } } The I want to change the response body for all API exceptions to a
