This problem is not related to Visual Studio, rather ASP.NET, and specifically MVC framework of ASP.NET—and I am sure the non-.NET Core version.

Can someone give me a document on how to create MVC app in visual studio 22019
The problem is same in both the IDEs, they are not much different. Make sure that you have downloaded and installed the Web development stack for Visual Studio 2019—yes, Visual Studio 2019 focuses on the stacks, and not the SDKs only.
See here for more on that,
Modern Web Tooling | Visual Studio - Visual Studio[
^]
Creating the ASP.NET MVC based project is also possible, as long as you download the .NET framework as well as the web development SDKs, and next steps are same; File → New Project → ASP.NET MVC.

I was able to find bootstrap.css file somehow.
Linking any CSS file is done the same way as you would add any CSS file,
<link>: The External Resource Link element - HTML: Hypertext Markup Language | MDN[

I would highly recommend since you are learning, that you start with .NET Core, as that provides a more control on the development, as well as the deployment for your application. Bootstrap and other front-end technologies are integrated right out of box, and many samples are provided that provide Angular or React samples that you can start with.
You can also use the
CDN based instance of Bootswatch[
^] and use the CDN alternatives, rather than downloading the files to your machine—which might decrease the development experience as the resources would not be available for development if network goes down.
