.Net Tips – tools to help you find a new Guid string

Ever needed to get your hands on a new Guid without having to start up a new project and all of that? Well, there are two easy ways to go about it:

1. use LinqPad

LinqPad is a FREE code snippet editor for C#, developed by Joe Albahari (one of the authors of the C# in a Nutshell books), and can be installed or run as a standalone executable. You can easily write a few lines of code like this and just grab the new Guid from the output window:

var newGuid = Guid.NewGuid();
newGuid.Dump();

2. use Visual Studio’s build-in tool

There’s a little build-in tool in Visual Studio which you can use to create a new Guid, go to Tools -> Create GUID.

In the new window, just copy your new 32 digit Guid from the Result box, and if you don’t like it for whatever, you have the option to create another one by clicking the ‘New GUID’ button.
