Project migration from WindowsForms to .NET Core. Where to look?

Question

.NET

Hello everyone, I have developed an application in C# using WinForms. The main functionality of the application is the administration of ActiveDirectory users.
And the idea came - to implement all this in the browser. I read about new technologies and decided to do it on .NET Core. At the moment, cross-platform itself is not needed, the server will be on Windows. But anything can happen, and the technology is kind of cool. I have no experience in web application development. And as a beginner, I have a question - which UI Framework should I use to display the user interface? Beautiful interface. With WinForms everything was easy, drag a comboBox or DataGridView and start working, but on the web it's not so easy. Thousands of different controls are not needed, basically standard comboBox, dataGridView, tabControl are required, and further down the list. Some controls have been changed, for example, to draw custom elements in the tabControl header, multi-select in comboBox, filtering in dataGridView, etc.
In general, please advise in the direction of what to look.

Answer 1

This is a paragraph. You have a lot to learn, I'll tell you.
Firstly, to implement "in the browser" - do you even understand what you basically need to do and what components to write on? "frontend development", "backend development" mean something to you?
You need to look towards understanding what application logic should be performed on the server (and you can write it under .Net Core), and which one - on the client (and .Net Core, in general, has nothing to do with it).
Well, yes, I hope you understand that .NET Core and ASP.NET Core are not the same thing, and "make a web application on .NET Core" is a very vague statement. What does it even mean to you?

Answer 2

.Net Core does not know how to work with ActiveDirectory (or rather, at the time of the beta, it was possible to run ASP.Net Core under full .Net, not now). Just use ASP.Net.
