What’s the main difference between using the options Guid.Parse() or new Guid() to convert a string in a Guid?

And which of the two approaches would be best used?

var usuarioId = new Guid(User.Identity.GetUserId())

Or

var usuarioId = Guid.Parse(User.Identity.GetUserId())

c# .net guid

Essentially none except for the fact that one is a builder and the other is a manufacturing method.

Builder’s source.

Source of the Factory Method (this is called from the original just above its source, only checking whether the string is valid). Note that the code already uses C# 7.x optimizations

In both those who do the parse is the intern TryParseGuid().
