ASP .NET Core Telegram Bot, how to run bot locally?

Question

ASP.NET

Hello everyone, I'm trying to create a Telegram bot on ASP .NET Core, I created a Web Api application, I have the code:

public static string Url { get; set; } = "???";
public static string Name { get; set; } = "тут название бота";
public static string Key { get; set; } = "тут токен";

but I don't know what to do to start the bot and test it locally, what should I specify in the Url field?
