The idea is after making the registration, send the user an email containing a link, where he can actually confirm the registration and only release the permission to log in. Just to have a little more security and prevent any email from being registered. How to do?

Using an attribute called [EmailAddress] in your email field. It validates perfectly if the string is a valid email or not.
[EmailAddress]
public String MeuEnderecoDeEmail { get; set; }
For this, you need to create a default for the confirmation. For example, a token in base64. Follow two methods to generate a token:
public static string Base64Encode(string minhaString) {
var bytes = System.Text.Encoding.UTF8.GetBytes(minhaString);
return System.Convert.ToBase64String(bytes);
}
public static string Base64Decode(string stringCriptografada) {
var bytes = System.Convert.FromBase64String(stringCriptografada);
return System.Text.Encoding.UTF8.GetString(bytes);
}
Make a method that generates a token like this (the input string you define) and save it to yours Model.
To set up an email, you can use a service like the Sendgrid that already has a good solution ready to be used. Here they teach how to assemble and send an email through their application.
Got it. But my doubt remains on how to send this email. I have seen some code using asynchronous controllers. You would have some example or more concrete tutorial?
@Ryansantos I updated my answer.
