I'm developing an asp.net core 2.2 project and due to hierarchy of menu levels I had to create subareas (Controllers, views, etc.), so I followed a c-sharpcorner article relate with that and it worked succeded, however article doesn't mention about creation of asp-subarea form attribute tag helper, I read about Microsoft author tag helpers but is not very clear for me since asp-subarea depends on other attributes like asp-area and asp-controller to build the final action attribute into the form tag.
I'd appreciate any help about. Thanks

When you add Identity to your ASP.NET Core applications, you can scaffold its Razor pages.
I am looking for a way to extract my views from a referenced RCL just like Identity.
I mean I want to create Area and related files (cshtml) to help developers to customize it (not a specific UI as you see in the above pic).
Do there exist any command-line tools to a way to extract Razor pages (.cshtml)?
I checked inside of a Razor class library with dotpeek there is no HTML resource, everything is class.
Any idea?
When I create a web project using "ASP.NET Core Web Application" / "Web Application" (non-MVC) / "Individual User Accounts"... I get the sample project with Register and Login buttons that show their respective pages when I click on them. HOWEVER... the very weird thing is if I search for "Create a new account" which is on the register page it's not found... and more... there is no AccountController in the Identity area or anywhere... so 1) the pages aren't anywhere in my solution folder and 2) how in the world are these pages showing up?!? I've tried on two different computers now. (using Core 2.1)
As an example this link works:
<a asp-area="Identity" asp-page="/Account/Login">Login</a>
and takes me to:
https://localhost:44300/Identity/Account/Login
and yet my folder structure (both in the solution and on disk) looks like this:
ASP.NET Core 2.1 with Identity automatically includes the "Default UI". It's a Razor Pages class library that's referenced via AddDefaultIdentity in Startup, which under the hood literally calls AddDefaultUI.
If you want the actual files in your project, you need to scaffold them in. Right click your project in the solution explorer and choose Add > New Scaffolded Item... Then, click the Identity listing on the left, and then the Add button. A new window will pop allowing you to select the pages you want included, your context, etc. Configure it how you like and go.
It's also worth noting, that as long as you use AddDefaultIdentity, the default UI is still included, which means you don't actually need all the scaffolded files if you want any of them. They'll essentially function as overrides. Anything specifically included in your project will be used, while anything that's missing will be pulled from the default UI.
This also means that if you want to do something like use standard controller actions and views instead of Razor Pages, the default UI will still be active, and take precedence. You have to use AddIdentity or AddIdentityCore instead of AddDefaultIdentity if you want the default UI off completely.
ASP.NET Core 2.1 introduced Razor UI in class libraries. Identity with it's UI is in nuget package.
The nice thing about this is you can now package UI with your libraries and then expose the UI for overriding.
This post describes how to override the UI. Essentially, you add the pages you want to override to your project to /Areas/Identity/Pages.... the easiest way currently is to run the scaffolder for identity and a visual walkthrough.
I'm attempting to customize the Piranha CMS system. I'm interested in changing the layout, setting up my own styled menu and tweaking where the content on the page shows up.
Is the intent that I modify the _Layout.cshtml file to my liking?
If there's a page in the documentation that covers this, please helpfully provide the link. :)
Piranha CMS is just a framework for content management, not a website template with widgets, themes and stuff like that :) With that said, a basic Piranha CMS project is basically a standard MVC project with two included controllers, one that loads the model for a requested page, and one that loads the model for a requested post.
This means you can do anything that you can do with any normal MVC application when it comes to styling and modification.
There exists some helpers for rendering Menus, Breadcrumbs and so on. Documentation for the helpers can found here:
http://piranhacms.org/docs/api-reference/site-helper
http://piranhacms.org/docs/api-reference/ui-helper
For the helper methods that render html there are hooks for overriding all content rendered so that you can change the standard menu to your own style of html if you need. Documentation for the hooks available can be found here:
http://piranhacms.org/docs/api-reference/hooks
Regarding what can be achieved with Page types and creating templates with different regions you can check the following pages:
http://piranhacms.org/docs/pages/page-types
http://piranhacms.org/docs/pages/page-model
http://piranhacms.org/docs/pages/regions
http://piranhacms.org/docs/extend/extensions
I hope this helps you a bit.

We use DataAnnotations for our viewmodels in our ASP.NET MVC 4 application.
In standard MVC these can be used to generate the markup for jQuery validation.
As we are using DevExpress ASP.NET MVC controls (v13.2), I was wondering if those DataAnnotations attributes can also be generated by the DevExpress controls.
I saw an example where the settings object was used to mark a specific property as required, but that was not with the usage of the DataAnnotations.
All Standard / MVC Validation Modes are supported. Check Docs and Demos.
I'm upgrading from .NET 2.0 to MVC 4. Back in .NET 2.0 webform, we had to inject license information on the fly to the footer of the software by override the "Render" function in .aspx.cs page (using HtmlTextWriter), find a particular spot of the footer and then insert the license text info there.
The reason I don't want to directly put that in the viewstart page or any razor page themselves using HTMLhelper is because I don't want my customers to mess with it. So hard code is not an option.
I use Glimpse and I see Glimpse is enabled by adding a HTTPModule,etc in web.config and magically, an icon appears on my app. Something similar ?
Bottom line is, I need to hijack the finished HTML output, modify it and return the final result to client.
How do you do this in MVC? HttpModule?
Thanks!
Glimpse uses a feature of ASP.NET called a ResponseFilter to change the output HTML on the fly.
The ResponseFilter, in the case of Glimpse, is set inside the HttpModule - but it could be set anywhere.
Four Guys From Rolla has an old but still relevant article on how to create ResonseFilters.
