使用ASP.NET Web API 2进行外部身份验证-Microsoft现在无法正常工作

Question

I configured External Authentication Services within my ASP.NET Web Api 2 successfully for Facebook, Google, Microsoft & Twitter about a year ago. Revisiting recently I was quickly able to get everything working again for everything besides Microsoft. I originally followed a tutorial similar to this one .

The first error I was getting was below -

/api/Account/ExternalLogin?provider=Microsoft&response_type=token&redirect_uri=https%3A%2F%2Fwww.censored.com%2Fapi%2FAccount%2FAuthComplete&state=PgiSt-woFC7HSvc990RM5RXVdkW_ozDKy3PDpDeyeAU1&client_id=censored& error=access_denied HTTP/1.1" 302 0 " https://login.live.com/oauth20_authorize.srf?client_id=0000000

I deleted the app at https://apps.dev.microsoft.com thinking re-adding it may fix the problem to discover I was unable to re-add it in such a way as to generate a ClientId & Client Secret. Has Microsoft support for OAuth completely changed and what do I have to do now?

Here is part of Startup class that shows how I am configuring Facebook & Microsoft OAuth.

public partial class Startup
{
    public static OAuthAuthorizationServerOptions OAuthOptions { g

    // For more information on configuring authentication, please 
    public void ConfigureAuth(IAppBuilder app)
    {
        // working 
        var fbook = new FacebookAuthenticationOptions
        {
            AppId = "sadfsda",
            AppSecret = "dsfsadf"
        };
        app.UseFacebookAuthentication(fbook);

        // not working
        var msoft = new MicrosoftAccountAuthenticationOptions
        {
            ClientId = "sadf",
            ClientSecret = "zdfsdf",
        };
        app.UseMicrosoftAccountAuthentication(msoft);

Answer 1

I was able to fix this after reading some of the comments from the GitHub link. I created a new App at https://apps.dev.microsoft.com skipping the guided setup. Then I retrieved the password with the Generate New Password button. This and the application Id (a guid) I used for the ClientId and ClientSecret. Added a Redirect URL eg

https://www.sadfsdaf.com/signin-microsoft 

and it worked.
