.NET Web API Build Pipeline

Repository with Azure Pipelines setup example

Navigate to Azure Pipelines Dashboard
Log in and create a new pipeline.
Go to Pipelines -> Builds -> New Build Pipeline
Go through the wizard: Connect to GitHub Yaml -> Select Repo -> ASP.NET Core Project -> Review
On Review stage, refer to the Yaml below for how to approach creating a build artifact for a .NET app

The artifact produced is placed into myArtifacts directory.

Steps at a glance:

Next step is attaching the created artifact in the Build stage to Releases pipeline.

Below is an example release stage configuration, deploying to Pivotal Platform:

The screenshot assumes you’ve placed your artifacts into drop directory in the PublishBuildArtifacts step
