Create a bug in Azure DevOps Services using .NET client libraries

Azure DevOps Services | Azure DevOps Server 2022 - Azure DevOps Server 2019

Creating a new bug (or any work item) is pretty straight forward. You just need to set the field values and send a JSON-Patch object to the REST endpoint.

Prerequisites

You must have the following before you can create a work item.

Create a C# project in Visual Studio

To learn about C# programming within Visual Studio, find the Visual Studio C# programming documentation

C# code content

There are a few things happening in the following code sample:

  1. Authentication
    1. Creating credentials using your PAT
    2. Creating a VSSConnection with your Azure DevOps Services URI and the credentials
  2. Retrieving the client using your VSSConnection
  3. Creating the bug
    1. Create an array of objects to set the field values
    2. Convert that array to a serialized json object
    3. Send that serialized json object to the REST endpoint
