Why is there no TabControl in my VS2017 toolbox - asp.net

I'm working on an Asp.Net project - why is there no TabControl in my VS2017 toolbox? Every resource I've searched just assumes that the control is there.

Based on my research, there is no default tabcontrol in the Toolbox.
You can refer to the following link to know how to create the tabControl in the asp.net webform project.

Asp.Net Core MVC Movie App - Scaffolding Item not working properly

I am following the tutorial for Creating a Asp.net Core MVC App.
Asp.Net Core MVC Movie App
I am at the point where i am needing to scaffold the movie model.
I am right-clicking on Controllers --> then am going to Add --> New Scaffolded Item...
I click on it and it displays something completely different then what is expected. Here is what it is displaying:
How do i get the display to show what is showing in the tutorial? What am i not understanding? Thanks.
After going through the above suggestions, I still wasn't able to get the proper items to display for me. I then finally decided to uninstall Visual Studio 2017 and do a fresh install. I created my project, added the Entity Framework dependency, and now the proper items are displaying.

ASP.NET 4.5 How do I use an Ajax controls, I can't find them in the Toolbox?

total newbie to AJAX, I got the NuGET an I found the Ajax Control Toolkit
7.1213.0
I ran this PM> Install-Package AjaxControlToolkit
It said successful at the end.
There is nothing to add if I right click a TAB in the toolbox and look in the .NET Framework components.
It says The Ajax Control Toolkit contains more than 40 controls, including... Where do I see them and how do I add them to my WEB page?
I see an 'AJAX Extensions' tab in my Toolbox which was there already, but there are not 40 controls. Just these
Pointer, Scriptmanager, ScriptManagerProxy, Timer, UpdatePanel, UpdatProgress
Are these suppose to be controls I can drag onto my WEB page or how do they work?
First of all you have to take a look at the sample.
Second, you have to download the AJAX-Control-Toolkit and you will find example projects.

ASP.NET Add Razor page in Web Application not Web Site, NO MVC

I just found a strange thing in Visual Studio 2010.
I can add a Razor page into a Web Site project, but I cannot do it in a Web Application project.
I do know I can create a ASP.NET MVC(1-4) project which allows me to add a Razor page into it.
After I checked the differences between Web Site(WS) project and Web Application(WA) project, it seems to me that WA is to trend to be in most cases and has more features than WS.
So my question is:
Visual Studio 2010 allows us to add a Razor page into a WS project(you can find it when adding a new page in the list of templates), but why it does not provide the Razor page in the template in the WA project?
I'm curious about it. Waiting for your answers :)
Cheers
I had the same problem when creating a new, Empty web application. I wanted to use MVC. Despite adding the references required, it still won't let me create files by right clicking on a folder.
However, if you have SP1 installed on Visual Studio 2010, you can:
Right Click > Add > New from Template> Razor MVC View
Hope this helps.

WPF DataGrid not appear in Toolbox?

I am working with Visual studio 2008. I want to work on WPF DataGrid control.
I downloaded WPF toolkit and install it, and then added toolkit reference in my project, but it does not recognize Datagrid control, and does not show it in Toolbox, I even try to add it in toolbox through choose Item.. but when I click WPFToolkit.dll, it gives the error. And even if I write code in XAML it does not recognize dataGrid.
Ensure you have selected the WPF Components tab before pressing browse. You are telling it to look for WinForms controls in your screenshot.
