Why this GUID generator for Microsoft workflows?
- Built for GUID-heavy engineering tasks in the Microsoft ecosystem.
- Works as a quick source of test IDs for C# and .NET development.
- Supports v7, v4, v1, v6, and v5 modes so you can choose random, time-based, or deterministic generation.
- Developer Copy Mode outputs ready-to-paste formats for plain, quoted, SQL, JSON, JavaScript, and Python snippets.
If you prefer the standards-first naming style, use the sibling UUID Generator.
Common GUID scenarios in Microsoft stack
- C# domain models and DTO identifiers.
- Entity Framework keys and seeded records.
- Windows Registry identifiers for software settings.
- COM class/interface IDs and integration configuration.
- App configuration files, environment variables, and deployment templates.
How to use this tool with C# / .NET
- Pick a version (v7 default, or v4/v1/v6/v5).
- Set quantity and formatting options.
- Generate and copy the output.
- Paste into your C# code, config, or test data.
using System;
var fromTool = Guid.Parse("d85b1407-351d-4694-9392-03acc5870eb1");
var newGuid = Guid.NewGuid();
Console.WriteLine(fromTool.ToString("D"));
Console.WriteLine(newGuid);
FAQ
What is a GUID in C#?
In C#, a GUID is a 128-bit identifier represented by System.Guid. It is commonly used when IDs must stay unique across databases, services, and distributed systems.
GUID vs UUID
They refer to the same 128-bit identifier format in practice. GUID is the Microsoft naming convention, while UUID is the standards-oriented term.
How do I create a GUID in .NET?
Use Guid.NewGuid() in .NET to generate a new GUID value. You can then format it with ToString() or parse it later with Guid.Parse().
Can I use this GUID in C#?
Yes. The generated values use the standard GUID/UUID string format, so you can paste them directly into C# code, config files, database rows, and API payloads.
