问题 I'm currently creating a multi-tenant web app using .NET Core. And is facing a problem: 1) The Web App serves different views and logics based on a set of domain names . 2) The views are MVC views and stored in Azure Blob Storage 3) The multiples sites share the same .NET Core MVC controllers therefore only the Razor views are different with small logics. Questions.... A) Is that possible? I created a MiddleWare to manipulate however I couldn't assign FileProviders on context level properly

ASP Net Core - Mixing External Identity Provider with Individual User Accounts for Audit Tracking

阅读更多关于 ASP Net Core - Mixing External Identity Provider with Individual User Accounts for Audit Tracking

I have created a default ASP Net Core MVC web app with Individual User Accounts. I added a custom UserID INT field to the AspNetUsers table and linked this as a foreign key to all my other custom tables so I can track what users inserted/updated records in my database. I did this as I prefer using INT fields for primary keys. In this scenario everything is working fine. I am now thinking of using an external identity provider such as Azure Active Directory however I cannot work out how I would link a user in Azure AD (or any other identity provider) to my local database tables to maintain the

阅读更多关于 In MVC6 how can I block direct access to a folder in wwwroot?

问题 We're developing an application in the latest MVC framework and everything so far has been great. In our application we have decided to embed an angular application in the project under wwwroot/app. I created an app controller and view and prohibited access to the app unless users are authorized. This works great when unauthorized users try to go to localhost/app - it kicks them back to the C# application login page. I want to take it a step further and also prohibit access to direct files in

Is there a session start equivalent in .Net Core MVC 2.1?

阅读更多关于 Is there a session start equivalent in .Net Core MVC 2.1?

In MVC 5 you could assign a value to session in global.asx when the session started. Is there a way you can do this in .Net Core MVC? I have session configured but in the middleware it seems to get called on every request. nercan's solution will work, but I think I found a solution that requires less code and may have other advantages. First, wrap DistributedSessionStore like this: using System; using Microsoft.AspNetCore.Http; using Microsoft.AspNetCore.Session; using Microsoft.Extensions.Caching.Distributed; using Microsoft.Extensions.Logging; public interface IStartSession { void

How to self-host ASP.NET 5 MVC6 application

阅读更多关于 How to self-host ASP.NET 5 MVC6 application

Just started learning ASP.NET 5 / MVC 6 I'm curious about self-hosting such an app outside of IIS - as a Windows service. Should I be using TopShelf for that, like it was the case with OWIN/Katana apps, or does ASP.NET 5 provide some built-in self-hosting (as a service) options via a NuGet package? You can use the Kestrel library for self-hosting. Add dependency to the library in the project.json file: "dependencies": { "EntityFramework.Commands": "7.0.0-rc1-final", // Dependencies deleted for brevity. "Microsoft.AspNet.Server.Kestrel": "1.0.0-rc1-final" } Then scecify this command for Kestrel

问题 I am developing an API with ASP.NET Core and I am struggling with the exception handling. When any exception occurs, or in any controller where I want to return custom errors with different status codes, I want to return JSON-formatted exception reports.

How should I return JSON exceptions in an ASP.NET Core API? 回答1: An exception filter (either as an attribute, or a global

问题 I am trying to use cookie authentication in an Asp.net core app (dnx 4.5). Note that because I have a custom authentication mechanism (radius), I am not using the out-of-the-box mechanism provided by core Authentication. When the user is not authenticated I want to redirect to a login page. I have added in Startup.cs the following code. The idea is to be redirected to the Login Controller when the user has not been authenticated: app.UseCookieAuthentication(options => { options.LoginPath =
