问题 I am new to ASP.NET MVC and as of right now I have the basic understanding of how MVC works. I have created a simple mvc website which uses only one project utilizing the pattern Model-View-Controller.

问题 Using VS 2017 with MVC 5 Razor views. When I publish my application, a handful of specific views do not get copied over. I'd discovered several SE questions on this same issue from back in the 2010-2011 timeframe.

问题 Implementing Facebook login in MVC 5 template, had added the app Id and secret code. Initially login was failing as it was returning null public async Task<ActionResult> ExternalLoginCallback(string returnUrl) { // Crashes on this line var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync(); if (loginInfo == null) { return RedirectToAction("Login"); } } After searching came across a solution which says to replace existing ExternalLoginCallback method with this [AllowAnonymous]
