AttributeRouting | routes using attributes on actions in ASP.NET MVC | Model View Controller library

I have an Asp.net 4.5 MVC5 app using SimpleMembership for Authentication and Authorization in App. Now I need to integrate to use external IdentityServer4 for Authentication. I tried to add OWIN Startup file into the project and turn off standard IIS authentication in web.config. Now I could be redirected to IDServer for Login and Consent.

Issue occured when it get to the view:

Error message:

No user found was found that has the name "". Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: No user found was found that has the name "".

My IdentityServer is the clone of IdentityServer4 quickstart sample. My MVC5 App is old and use SimpleMembership for Authentication and role Authorization. I manually added the OWIN Startup.cs see below code.

I tried to use IdentityServer https://demo.identityserver.io as IDServer and got same issue. This proved my IDServer has no problem.

I tried to created a simple separate Asp.net 4.5 MVC5 project without SimpleMembership, it doesn't get the error.

I have a project with Attribute routing like:

I have been searching a lot, both online, and debugging, re-read docs for dryioc and took a look at the samples. I don't think my issues lies with dryioc, or maybe I'm overlooking a silly mistake.

Project setup => service => owin + webapi2 Using attributerouting, swagger and apiversioning

This is how I setup my container

On MVC, I added top the َAdmincontroller [Authorize] to check if it was not logged in redirect to the loginpage. When you want to enter the Adminpage, it redirect to Loginpage.if you enter the correct information Send it to the admin page if you enter the wrong Then enter the correct password it redirect to HomePage I do not know what the problem is

Controller Login

I can't get a catch all route to work in MVC. I have tried to implement what is shown in this question, but it does not work. I have a controller called OnlineController with an Index action. My RouteConfig.cs is set up like this:

I just put my website created on visual studio on a window server (1and1) and I am getting an error

In case you can't read it, it says

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.

It seems like there is something wrong with the web.config.

Here is my web.config

i have a loop like this in my view that generates the list of student`s names

Below is the controller which has following actions.
