using System; class Program { static void Main(string[] args) { Guid uuid = Guid.NewGuid(); Console.WriteLine(uuid.ToString()); } }In this example, we have imported the System namespace and use the Guid.NewGuid() method to generate a new UUID and store it in a Guid object. We then use the ToString() method to convert the Guid to a string and print it to the console. To use the UUID library in C#, we do not need to install any additional package. The System.Guid class is a built-in class provided by .NET framework. In summary, UUID is an important identifier for objects in a distributed system. C# provides easy ways to generate UUID using the System.Guid class. There is no need for any package/library to use the UUID functionality in C#.
